PC Troubleshooting No Post Diagnosis (NCIX Tech Tips #54)

[ChrisArnol9010]

I took a look on my motherboard and I looked at the CLR CMOS pins and there wasn't a jumper on them. Do I need a jumper, and if i do, will that be the cause of my no post/no signal problem?

[shazyriver]

my problem is quite same.

I get no display no beep

no power led

the fan runs psu runs.

still no beep no display. I dont have a card either.

Please HELP ME

[Bey0ndKha0s1825]

make sure your processor has dedicated graphics. if not, thats why

[shazyriver]

@Bey0ndKha0s1825 Can u plzz

Clarify ?/?

[Bey0ndKha0s1825]

@shazyriver Well if you have a CPU that doesn't support on-board video, it won't work. The fans will turn on, but you won't have a display on your monitor. If you're using a Sandy Bridge processor, then you need a card, because it doesn't support on-board video. Let me know what you're using and if this is not the case, I'll still try to help out.

[Bey0ndKha0s1825]

@shazyriver Sorry, I made a mistake on my last comment. The processor itself DOES support video, BUT if you have a P67 motherboard, you NEED a card. Sorry for any confusion.

[shazyriver]

@Bey0ndKha0s1825 my board do support on board video. Its an old board. msi d865. It was working perfectly..

[Bey0ndKha0s1825]

@shazyriver Just double check all your cables are plugged in/ PSU switch is on. If not then maybe you have a bad CPU or RAM. :/ sorry if I couldn't help out.

[shazyriver]

@Bey0ndKha0s1825 I have tried it all

i think by board is dead

the only option i me left with is to replace it

what would u recommend me 2 buy

should be economical ??

[Bey0ndKha0s1825]

@shazyriver Yeah, it must be a dead board. What processor are you using? Also, do you want to overclock/want features on-board/etc.

[shazyriver]

@Bey0ndKha0s1825 its 2.8GHz pro no Overclocking needed

just a normal pc 2 play cs and nfs...

[Bey0ndKha0s1825]

@shazyriver Intel/AMD?

[shazyriver]

@Bey0ndKha0s1825 Intel

[Bey0ndKha0s1825]

@shazyriver What processor exactly. Do u know?

[shazyriver]

@Bey0ndKha0s1825 Intel Pentium 4 2.8GHZ

[Mergh06]

You saved my life too. I want your earrings now;)

[billonicle]

an easier way of clearing the bios is to take the battery out and hold the on button for a sec or 2

[ninjadude991]

Actually there wasnt anything wrong except the ram he kept the tv off

[DisTrictXProductions]

lol all this trouble, and now we have Dr Debug :D gotta love it

[adobo777]

Clearing cmos works %99 of the time.

[ethanalex102]

@adobo777 whats happing the other 1% of the time???

[adobo777]

@ethanalex102 damaged CPU/mobo pins.

[WeakGuy]

Clearing the CMOS worked for me - many thanks!

[TheSSLPowa]

I have encountered 3 long beeps. I just unplug the system, wait for a bit, turn it on and it works nicely.

[zpezza]

oh btw for my last comment if thats your problem you won't get any beeps and it will run fine just without display

[zpezza]

one other thing no one seems to mention is if you have your vga or dvi or whatever your using for display in your motherboards slot and you have a graphics card installed the motherboards slot may not work seeing as some boards happen to do that im not sure why. mine did and the board is a M4A88T-V-EVO/USB3 so if you have that board and dont get display that may be th problem.

[AngelOnez]

LOL, paper and metal can hold static charge, he puts the motherboard on cartoon and the ram on the PSU, even if the PSU is grounded you can't be really sure it has no static, very bad working conditions.

[mehmot97]

I once shifted my Rams and then ended up with from 3gb ram to 4,5 gb ram WTF does that mean?

[commentheory]

Linus plz help....I have a evga motherboard and I'm getting 18+ beebs on start up wich has progressed from about eight? Is it my ram cards what ima bit freaked cause this is a expensive custom built computer I don't want to mess my baby up?

[TheKahanex]

i have a problem when i boot up where i have to go to the bios and then back out to get it to boot up and if i dont it freezez up in the middle of loading up windows xp please help

[SOSLICK22]

lol, check if it's plugged in...Reminds me of the IT crowd.

[DatMasta96]

Thank you so much!!! it was my 4 pin connector that wasnt plugged in!!!! it was plugged into the Main motherboard power but not into the little 4 pin connector!!! I love you!!!!!!!

[DatMasta96]

lol this video is amazing cause i switched all my stuff from an old case to a new one and this problem happened to me...i think i broke the pci slot or my video card pins or both...

[Jdwill1014]

got a question im getting a msi p67s-c43 but i dont know were the case power button on the motherboard is someone help if they can i havent gotten my board yet or i would know by reading the mobo thingy thanks if anyone can help

[TechUpdateViewer91]

wt's up? I have Acer AS M3100 Desktop with AMD Athlon 641x2 4400+ cpu and motherboard is F690GVM. when i shut down/ restart my computer, their is no post and just Fan running, but no beep sound i am trying to find the jumper near the Battery, but not finding 1. any help please...

[cast390]

@TechUpdateViewer91 Try popping out the battery and reseat it.

[TheBestNewMusic2011]

Wow very nice you saved my life ;D

My pc works now :-)

[MegaGT93]

please help!i have a problem,when i turn on my pc,a screen appears saying "start windows normaly",i wait for the countdown to finish and then my pc restarts,and the whole thing goes on and on and on.................please help!!! :/

[tavi921]

@MegaGT93 select last known good configuration

[marky11789]

@MegaGT93 Reformat or restore ur OS . . .

[jrchurchman13]

if the tv isn't on until you change the video card, it's not going to work...

[pauloperez21]

or buy a new one lol!

[Mrkimtail]

Now that simple Simon has watched the video maybe he'll remember a little of the video to have an idea where to start or like John Q Public you can take it to the Geek Boys at BB and they can watch the video and fix your computer

[gentel916]

my pc shows the mother board logo and freeze ... any help ?

[qingqingyep]

@gentel916 Try update your bios....maybe your bios corrupt.

[gentel916]

@qingqingyep  how .... and it dont show the bios thingy like press F12 for bios

[qingqingyep]

@gentel916 Could't it be you graphic card problem?

[gentel916]

@qingqingyep i tried the on board graphics but same thing

[qingqingyep]

@gentel916 Well.Thats a big problem.maybe something is shorten out your motherboard and pls give more details about your pc build.

[gentel916]

@qingqingyep lol 1 of the worst build ever -,- ... intel i3 .. 16GB ram .. GT9800 .. and an intel media board

[qingqingyep]

@gentel916 All right.maybe thats the motherboard or RAM problem. try swap the motherboard and boot with 1 stick of RAM.BTW. the graphic card and the ram will bottleneck your entire system.

[gentel916]

@qingqingyep ik ... i am goning to buy a GTX560 ti ... and i5

[qingqingyep]

@gentel916 same motherboard?

[gentel916]

@qingqingyep depends on what i make ... if its enough ill buy a new motherboard

[Andrew123108]

my roommate was moving his pc into a new case using still his old old psu, when he turned the switch on the thing blew up. swapped the psu and it still wouldnt boot. after about four hours the problem was tracked down to the hard drive! the hard drive had blown and was shorting the system. so just bear in mind its not always what you would think.

[qingqingyep]

@artglidden There is the button to change the video singal input.try to find it and change to HDMi input.

[qingqingyep]

One more tips:Older boards don have cmos reset button . removing cmos battery can clear cmos 

[scott93257]

@qingqingyep

many of them don't...What sucks is this: On the much older boards the CMOS battery was soldered in...Thank God for clip in battery cradles..

[NorCalZepeda]

awesome



[262kk]

you can see camra man in the reflection of the tv!

[unstoppable5044]

@Amy01223

You will see a higher performance if you buy the second card. ie. higher frame rates (faster and higher res for games). Might also give you an advantage for faster rendering. (not sure about this) Go for it if you still have the extra money, but I think one card will be sufficient for gaming and other computer stuff..

[Amy01223]

Ook.. i need help with some think. i have a crossfire ready pc and i have got a ATI Radeon 6850 1028MB GDDR5 card. i want to get a 2nd card so i can crossfire them.. will i see any performance in my games if i do get a 2nd card or will it be the same performance as one card ?

i have a Asus M4A88T-V EVO/USB3 880G Socket AM3 ONboard 128MB Memory Crossfirex DVI VGA HDMI Out ATX Motherboard

thx amy :) xx

[NOLIMIT69NOLIMIT2000]

Can you get to post without any memory installed?

[MediaMocker]

@NOLIMIT69NOLIMIT2000 no

[qingqingyep]

@NOLIMIT69NOLIMIT2000 no...



[shafnet]

Get a PCI POST Diagnostic card for 5 bucks

[n1bingoplayer]

I also had this problem, i just called killslow for free. And they helped me, it's now fixed. Check my channel video.

[akoaymaganda11]

Guys Visit techyv.com ... I can always relay all my pc problems, forum , questions can be answered.

- just to share :)

[Grippen98]

Check and clean the Cmos.... that doesn't really sound right my friend.......

[Arthedes]

step one: turn display on

[enigma2213322133]

THANK YOU! I had no idea there were two places to plug up the motherboard

[Lenninct]

Thank you, this really helped me out get my comp back to normal.

[StreetLogistic]

Changed the ram, changed the HDD, changed the graphics card, changed the PSU, changed the motherboard, changed the processor, changed the case and still no post, all brand new parts and still nothing, spent about £2,000 on trlying to get this crappy heap of junk to work, Biostar motherboard, 16GB DDR3 ram, 4 2TB HDD's, AMD Phenom II X4 3.4GHz black edition processor, 2 GT 440 Gigabyte graphics cards and a 1000W PSU by coolmasters, any help would be of some sort of help to me but this SUCKS!!!!!!

[Vaclover1]

@StreetLogistic Gt 440 cant go in SLI mode try taking one away

[StreetLogistic]

@Vaclover1 Yeah I didn't say there was 2 in there though, I needa learn to type, lol! I got it working, turned out to be shorting out on the power swich, so now I'm using the on board one!

[JosephMorganFPS]

This Video Probably isnt that helpful to people cause they cant get on their computer to see it.

[ChillieDog7thStreet]

@JosephMorganFPS smatphone..........



[Tzeny15]

@NCIXcom I know what you did. At first the monitor behind you was turned off because it didn't show the insert a cable thingy, then, WITHOUT swapping the GPU you just turned on the monitor ;) Clever Linus....

[Tzeny15]

At 3:33 the DVI cable is in the lower part of the board and at 1:00 he plugs it in the top part. O.o

[whiskeyify]

lucky him he can just pull another card and put it in..this cracks me up...better to explain what we could do at home to fix this problem, we can't just walk into the warehouse and pull another card off the shelf. We could listen to the beep code and find out what it means...

[chronofusion]

um about clearning " cmos" or reseting the bios' you gotta leave it on the other two jumping pins longer than one measley second. best to leave it on there for at least 20. count to 15 slowly. I have PROVEN this with more than 5 different motherboards, 5 different brands spanning the past 3 years. cheers

[MasterAnzio]

hey i can see the cameraman in the tv reflection!

[MasterAnzio]

dude this guy is so fucking cool!

[urmean26]

The tv was off?

Nice vid tho

[MrIliff]

so did he test the motherboard then with just the -motherboard, ram, graphics card and a power supply, that was it, no hard drives?, just checking?, cause I got a new motherboard, ram and a graphic card I wanna check, I have power supply, so I can test my motherboard then?. (I have an Intel system but am in the process of building an AMD system but don't have all the stuff yet like hard drive and O/S for the new build). Just wanna check my new mobo works, can someone advise me, many thanks.

[TheMaristBoy]

What was that card anyway?

[skipper124]

lol nice guide but there is nothing wrong whit the system he just turn of the monitor and tell about the thinks that could go wrong and then after he came back he just turn the monitor on lol if you look close to the tv you see the blue light is on after he said that he replace the video kaart :D

[OneEyedJack1970]

Back in the AGP days, it wasn't at all uncommon for AGP cards to rock loose, due to the socket connector being placed almost in the exact middle of the card. I don't think I've ever had an AGP card work the first time I plugged it in.

[PauliusSmile]

4:39 Look at the 24pin connector :D

[Films4You]

Look for bulging capicitors, a sign of fail

[BassPounderX]

i think the camera man is like his little brother or somethign assumng he has a little brother

[Reconciliasion]

LOOK CAREFULLY U CAN SEE THE CAMERAMAN IN THE TELLE :D

[TheZenoid]

Isn't there an electrical hazard using that method to start the motherboard (screwdriver)? I tensed up each time you did it, lol.

I'm trying to fix a friend's computer, which we believe to be his motherboard (and/or processor). I currently don't know how to troubleshoot a processor, but, what's happening is, he turns on his PC, the fans race, but no POST, no picture.

Thanks for these tips as I'll be able to rule out ram sticks and test for a beep code at least.

[xArnthorx]

@TheZenoid Do you really thnk the motherboard would be able to pull that much power through itself to kill linus? No. Also comeon man the screwdriver obviously has a plastic handle.

I had this problem recently, first make sure the ram is seated properly then you'll need to find another mobo or compatable cpu unfortunately to test.

[langyman20]

didnt work

[RyanReding100]

No POST. Can you help me?

Motherboard = Asus Sabertooth X58

Memory = Corsair XMS3 6GB (3 x 2GB) CMX6GX3M3A1600C9

Power Supply = Thermaltake TR2-600W

Graphics Card = EVGA GTS 450 1GB

[Discoman400]

cant get past the bios step. i cant find it on my mother board

[soulassssns]

I have a pc that wont even power up at all. No lights no spinning fans nothing! I know or assume the psu still works because it will spin up the fans on another mobo. Any ideas?

[Jailbroken671]

unclear view of CAMERAMAN!!!!

in the first 30 secs of the video

[zen699]

hey everyone! I fixed my PC with dental floss, no joke!

[Unasigad]

@NCIXcom I have an acer travelmate 2414 nlci and I cant get it to power up. P.S The chargers light also blinks when I connect the jack into the power connector. Is there any way to fix this problem?

Thanks!

[altec122]

be sure to check if your monitor/lcd is on..

[MW2mostwanted]

Im studying comptia a+, Great advice, thank you,

[HeyMarkedOne8]

Hahahaha I can see man's reflection on monitor!XD

Is that so famous cameraman or some other guy?!XD

[nsoldiac]

THANKS!!!! I was about to return a whole motherboard until I saw your video and realized a missing 4-pin connection. Thank you so much!

[Tuscopa]

Lol. Funny stuff right at the end. Sometimes small things like that can REALLY put people to the test :)

[grooveclubhouse]

a lot of hate in here. Linus is following everything covered in the CompTIA manual. Love all the un-certified pc techies giving him gripe. lol

[MiniExtreme]

you should do an update of this =)

[smiletogreet]

very good and concise clear explaination ! thank you very much ! smarty young man !

[tazykills]

Linus, can a BIOS reset while the computer is on damage anything? Thanks

[Fallacy99]

Ok Linus, now take it a bit further. The GPU is faulty, how and what can be done to repair it?

If the Mainboard has failed, what can be done to repair it?

My PC didn't POST

I replaced my Mobo and now it works fine. But I still have a board that I would like to get going again.

Performed open bench, cleared BIOS/CMOS all other components work. It's just the mainboard thats faulty, it powers up but doesn't POST.

It's a Biostar TA780G M2+ used for just over a year at stock settings.

Thanks

[justmymage]

No post/no signal problems must be the 1 of the most annoying 1´s, since i have had it over 5 times (in like 2 years, ARGH!)

There should be a own shop for ´´no signal/no post`` problems since they can have many reasons and you wont waste extra €£$ on trying to find problem (i wasted over 300€ and still did not find da problem >(. )

But if some1 would make make that i bet many people would go there (or atleast i would)

[lulutzkeloo]

I need a tip :D

I know that the Mother Board or the CPU is the problem

But how do i know witch ???

[lulutzkeloo]

hi i need a tip

I know is the Mother Board or the CPU

how do know witch ???

[forlatagate]

hi guys,need some help.pc was working,then

pc wont p.o.s..t .cpu fans spins,motherboard light is green,pci-e card fan spins.but no p.o.s.t

asus p5n e sli or

intel core 2 duo

kingston compatible ram kvr 6670

asus graphics card or i use bfg 7800 (test).

cleared cmos,messed around with jumpers,took out battery .

no beeps,nothing!help!

[forlatagate]

@forlatagate i dont get beeps as well

[jordanash84]

Linus FTW!!!

[cokefan3]

OMG!!! THANK U NCIX!!! This video helped to get my new build up and running. I am Happy ^^

[Weeman353]

On my first build i put the HSF on backwards causing no post, after 4 hours of freaking out i fanaly got it to work(AMD Phenom II X 4 945 HSF on MSI N750-G55 Mobo)

[voltjutsu]

Thanks for the tip, i built a pc for the first time and when i turned it on there was no POST. but the fans connected to the board, the gpu fans and hdd were spinning. the hsf fan was not spinning though. also the dram led and boot device led were lighted ( asus q-led feature indicating a problem ). can you give me an advice? it will be highly appreciated, thank you.

[DFFAS2009]

ha you have Ati 3870 LOL I have the same

[TheWoWRevelation]

why and when do you clear CMOS?

[Alex148710]

@TheWoWRevelation If the settings in your BIOS are wrong or corrupt (e.g. Overclock failure) then clearing the CMOS will bring everything back to stock values which will make you post again.

[ANGamingCommunity]

Hey, I'm aware of the chances of someone replying to this are slim but its another thing im just gona try.

Ok So I'm having a problem with my PC. When everything is connected, the computer will power-up, then abount 5 seconds after that restart. I'm getting no beeps or anything from the system, it just immediately shuts down.

At first i though it was the ram, so when i removed the ram, the computer posts that there is no ram, however it remains powered up fully, anyone have an insight to this?

[Mistiestblue]

<3 Thanks :)

[traction517]

hey, so if it beeps at startup then it means defective ram? because when i turn on my comp it gives me two beeps.

amd phenom ii x4

nevidia geforce 9800gtx+

4gb corsair ddr2

msi k9a2 main board

[mohsun123]

i recently changed the motherboard on my htpc and the new motherboard wont post. i have replaced it 2 times and still no post. i think it is just a driver issue with windows 7 ultimate 32 bit, but any suggestions?

[Alex148710]

@mohsun123 If you change your motherboard you have to reinstall Windows

[Scousar]

Hi

Here is a small improvement you can make to your video. Please mention the 110/220v setting switch that is on the back of most PSUs.

I just shipped some hardware (a web server PC) from UK to US and it wasn't booting, I had box open, swapped graphics cards etc.

I watched your vid and then remembered the 110/220v setting!

Although very few people will have this as the cause of a prob, some will and it will be very helpful to mention this. (It could even get moved by mistake).

Hugh

[lineriderSTi]

lol the tv was off the whole time

[uut0]

my pc once had a bsod for no reason. i was just watching vids on yt and studdenly bsod.

[iUseToBeDonovantys]

what happen if my system turn off/shut itself down for a few second and reboot normally to window whenever I start the system for the first time... this only happen when I overclock my CPU.. I can run stress test without problem

[smashdudez]

m4a79t-Deluxe juste dont post because its random and crappy, Never gonna buy asus again... i sent it because the audio controller was defective, i they send me a crappy mobo with post problems..

[MmmCouchPotato]

Hey Linus, can you do a No Post Diagnosis on notebooks?

[UmairNaeemKhan]

i can see the camera man at 2:26,......hehe

[pcfix411]

I watched and enjoyed the video

[vHellover]

Hi, Ok, i have o problem with a mobo GIGABYTE GA-7VA. I'd verified the CPU, Video Card and RAM on another mobo and they are ok. But when i put them on the GA-7VA mobo it dosen't post, it starts for about 4 seconds and after that it shutdown. I'd verified for short circuit or loose pin on the mobo and i found one capacitor with a loose pin (the + one) i soldered back and still nothing. What can i do more? Do you think the mobo is toast?

Thank you.

[MoonLightCoCo]

i just smack my computer with my cock and it starts working lol

[calcalownz]

that is funny

[The25Dudeman]

It's ATI that explains all your troubles...

[XLR84SPEED]

what card is that??? i know a lot about nvidia but i'm thinking about building a amd+ati rig plz msg me with this make an model thnx

[gravexx]

i do have the 8800GTS if you have any better card please send it for me and i will pay for the delevery !

[radwiimp]

Sometimes the ram isn't dead, you just have to fiddle with the volt settings with one stick in and then add back the other one. Mobos can be pretty picky when it comes to that.

[tripmatt1]

I turn on my homebuilt Pc and I get this error message that tells me settings have changed and to push F1 to continue.

[Bob8673]

I think your CMOS battery died

[testdirver]

hi if the mother has video and dont post to put another video card in the pci express the bios reconize inmediatly or not because already do all you do and nothing

[briskandpepsi]

lol nice blooper at the end. i don't know how many times i've done that myself... i'm like omg could it be the power supply? lol...

[TikiShootah]

what the hell. who on earth would have a "spair "400-500 dollar video card on hand to test if thier current one is deffective?

[WESTSIEEDE]

@TikiShootah rofl any video card will do smartass

[TikiShootah]

@WESTSIEEDE

wow did your retarded ass actually reply to a comment nearly a year old? get a life

[WESTSIEEDE]

@TikiShootah -_- think about what u just said for a second, then you will realise your the retard

[topazsin12]

@TikiShootah where did he say it have to be an expensive card?

[RyanReding100]

I Know right. I make minimum wage, which is 7 dollars an hour

[Trillios]

@TikiShootah who sed it had to be a 400-500 one?

[hiddindragon08]

@TikiShootah lol, it's not a spare that's identical to the one you're using. Many of us who've built a system or at least upgraded a video card, have that old video card laying around somewhere. If not, honestly, it's never a bad idea to spend 30$ on a cheap video card to have laying around when things go wrong, which as any computer geek knows, they will. You're testing the slot of the mobo to see if the slot is bad. If the other vid card works, then most likely your current video card = dead.

[blueovalfan23]

@TikiShootah not that it would matter but most boards have onboard video. some don't though. in which case you wouldn't need a high end card, just something to slop in there for testing/ temp use. maybe even barrow a card from a friend. personally i hold on to cards i upgrade from just in case. something else, i wouldn't want to use a high dollar card for testing. who knows, it could fry something.

[Ptro001]

@TikiShootah any cheapo WORKING card will work, you can buy your 500 dollar card afterwards as a replacement

[onebulletisit]

@TikiShootah you dont need to test it with the exact card you can use a $30 card..

[pitzaboyful]

@TikiShootah

Why dont you get like a 30 dollar cheap card in case this happens and you only use it if there is something wrong.

[MultiIPwnage]

I wish I saw this video before I spent 300$ to fix it (: c)

[arkuatic]

Theres a chip in the gold contacts of your first video card.

[galuple]

Its sad that the ad I'm seeing right now is for relationship advice.

[iheart707]

Very informative, one error that I had was setting the memory freq too high when I went out to go buy new ram. I had to find a stick at that freq to make it load even the BIOS so I could change it back. Like alot of people have already said, don't change crap if you aren't 100% sure what your doing in the BIOS! Great video by the way....

[Bayngan]

And the Camera man is visible through the reflection...wearing black T-Shirt ... :P

[fermixx]

you gotta be REALLY unlucky to have a wrong ram + wrong gpu

if they got out of warranty, feel free to jump from a bridge

[gonzo191]

i hate when there are computer errors u hafta take into account every little detail

[dale456654]

There is still something wrong with your computer :)
