Troubleshooting PC That Will Not Power Up

[ramste10]

reset the motherboard and sorry i haven't responded back in a while

[baxer182]

Thanks it did work!

[rossdaboss1959]

I have a hp dv7-1245dx. When i push power button, it lights up the fan comes on for about 2 sec, then goes off, n black screen. I took out rams n hard drive n put back, still nothing. The keys don't work to wake it up. I can't even play disc or get to bios. Is there anyway to restart the computer from a full shut down? When i hold the power button, it shuts off, but when i press again, it comes back to the same thing. I just need to get the screen back on. It seems sleep n won't wake up.

[samhuang1999]

@rossdaboss1959 i have the same problem, i think its a failing powersupply or processor

[rossdaboss1959]

@samhuang1999 Yea a lot of people are telling me it's the processor. It's no power going to the screen or key board. I'm going to get a processor. My computer don't cut off. I disconnect everything n put it back, n nothing.

[samhuang1999]

@rossdaboss1959 ikr, Im going to test the power supply with a DMM before I buy a new processor....

[l4dxpert1]

help! i built mine myself and it booted up but i didnt have any usb wires pluged in from the case to the motherboard. i dont know whether it is the power lead i use because i only used it as a test before i bought one. anyway after i tested it i switched it off and plugged them into the motherboard. i thought it might have been wrong so i unpluged it from the motherboard and when i went to retest it, it wont work. does the wrong cables have something to do with it or is it my power supply

[l4dxpert1]

@l4dxpert1 also the motherboard doesnt work with them in or out. have i damaged the motherboard

[TheMightOfDeath]

@l4dxpert1 If the motherboard is broken the colour changes to show it, i'm not an expert so i don't know which colour

[l4dxpert1]

@TheMightOfDeath ive made it now but thanks anyway ill think of that when i make my next one

[Gilly714]

Hey I just want to thank host definitely saved me shit loads of $ . Best Buy wouldn't even take it ...madthumbs to you pal.

[CougarBait654321]

The power switch? Really? I have repaired dozens of power supplies and never had to replace a power switch. The FIRST thing to check for this symptom is the CMOS battery. When the PC is OFF it uses energy from the battery to get things going.

[zXJulianXz]

@CougarBait654321 The power switch on my pc has gone before...

[lukesixtynineuk]

Hi,

I have a constant yellow lamp on (the motherboard) and a flashing green lamp but nothing else.

Completely dead.

Any ideas?

Thanks in advance.

[scotter2k9]

I turned my comupter off then in 5 minutes time i turned it back on again, it starts to boot up for 2-4 seconds AS i put the power plug in but then it just goes off, i can see through my case that the motherboard light (the power button on my mother board) is still alight but when i press that or the acuall power button on my comupter nothing happens; but yet if i unplug my computer and wait 2 mins then do it again it just does the same HELP!

[willfahmy1]

@scotter2k9 i have the same problem HELP

[Arthur5141]

how much would a motherboard cost

[xXconnorminton12Xx]

@Arthur5141 depends on where you shop and what kind of laptop you have,my laptop motherboard...im pretty sure.. is fried, but no signs, but i have a acer aspire 5517 and i got on ebay and there prices ranged anywhere from 100 dollars to 160 or 170, like i said, depends on were you shop..

[midrange18]

I've been having a start up issue for over 2 years now. As long as my computer is on, its fine.. if i restart it, its fine, but if i shut it down, it won't turn on. right away. All my lights light up, light on mother board, ethernet light, power button light, but nothing starts, no fans, no hard drive.. nothing. I keep trying and trying, and eventually it starts up like nothing was wrong. I recently learned that if i unplug it, hold the button, then plug it in, it will boot up fine.

[KJEboys]

I have an HP m8530f, had it a couple years now from BB. Lately its been freezing and bsod. Tonight it froze.. I powered down... then hit the button to turn on. I can see the light... but nothing on the the monitor... I shut off/on the monitor..it reads "no signal input."... again the pc light turns on.. but no signal to the monitor. What would cause this?? thanks.

[09052889735]

When i on my pc, their is a sound that i heard maybe twice or trice or something like that can't on..What is the problem on that?



[MsSasuSakuLove]

I was playing the sims 2 games right? well idk i was downloading all the sims 2 games i was finally donee :) right? well i was playing and all but then it crashed the screen was black black but it was abit black like covering from seeing the screen like when you turn it on its like that black well that black didnt go away until after a few seconds of taking out the battery. When I try turning it on these 2 mini lights in the bottom turn on and thats pretty much it. help please

[shrockerharder]

man first, u look gay, and next, speak louder!

[xmonkeyzpawx]

@shrockerharder man ur just a troll he is helping people like me fix my computer he is speaking loud u must be def?

[Darkcatcher19]

hi for some reason i left my power cable unpluged all day now it turns on agine weird what could of been the cause for it not to be on?

[MerlinProductionzzz]

my computer doesnt turn on... when i press the power button.. it lights up and theres 3 beeps and me mouse's laser light is on but nothing apears on the screen.. help please?

[shrockerharder]

@MerlinProductionzzz It might be your ram's problem. Try taking it out, then clean it. After that, Put it back on and start it up. Monitor issues mostly occurs on rams...

[Darkcatcher19]

i got the same prob my hp pc quad core wont turn on it's only 2 weeks old it worked normal last night so why would today be diffrent? plz send mail to me on here explaining diffrent stuff i can do to fix it cause i have no means of transport to the bestbuy store where i got it and i know geeksquad wont fix your pc at your house they'll say gotta take it in bah for 125 bucks to come out they can do it right at my house

[dell11700]

how do we check the psu for defects?.....for free?

[damian15006]

my computer is on but it does start up. i can hear my computer on and the light in front isnt on and my screen is blank ?

what you think is the problem ?

[Dr3aDnAuGhTz]

@damian15006 I would check your ram, ram is usually the issue to this problem also a graphic card that is bad or isnt in properley will do the same thing ---- hey from australian Network engineer and hardware technician ----

[Celltypewhatkind]

what if a smell came out of motherboard

[mikpau32]

I have a Pavilion N5240 which wouold not turn on at all ..nothing worked...All I did to fix this problem was to resolder the power jack connector socket on the mother board and that fixed the problem...

[kurdishusa]

Does a laptop turn on if the harddrive is off?

[fukingfaggotfukfuk]

i have a problem with the cpu, i changed my voltage from normal setting (im unsure what the voltage was set at, and i changed the cpu voltage to 200. i assume the numbers dont matter, all that does is i changed the voltage. im not too good with computers. now my computer boots, the fans turn on the LED lights go on and 5 seconds later, it shuts down. i did this about 20 times, im afraid if that if i try to boot it more it might melt or fry my psu. what do i do? get a new power cable? psu?

[TechieSal]

@fukingfaggotfukfuk Put everything back to Default settings... but since you did that.. im guessing if im not mistaken the changes actually happend on the mother board... so trying to make the motherboard back to default settting back would help.. if not then buying a new motherboard would be your choice

[fukingfaggotfukfuk]

@TechieSal thanks, but i havent set everything back to default since it wont boot up, i will try clear my CMOS memory so that i can reset my BIOS and cpu voltage especially, ill have to take out the battery and jumpstart my motherboard, somehow, ill put some research into it now. hopefully my motherboard isnt fried or melted..

thanks again :)

[Darklancy]

damn! Maybe i have to go check inside and what seems the problem okay

[ramste10]

you can't puch your computer that will mess it up more. I uesed to do that to mine and i would pay 900 $ every time i did that.

[ramste10]

it the power supply.

[Darklancy]

All i did to my computer is a weak punch then it turned off i on'd it then it wont on.. i know im stupid for punching the pc , please reply :(((

[damienlamy]

or try briging the green and Grey together with a piece  of wire duhh/h

[ranma6899]

ny pc turns on then it shuts off then i get a flashing orange light then turns green

[ihatelols]

I put the screwdiver somewhere white connector place and now my motherboard wont start the computer :Dit is something like pe2 , how to fix this ? :D

Doesnt even matter , i have now 5 times better computer ;)

With 4.5 ghz processor 6gb memory and 1 gb graphics ;)

Old one was 2.8 ghz , 256 mb graphic and 512 mb memory :D

[jamo387]

This guy is absolutely right . Cheapest thing to do is try another power supply and short the power on pins. I also like to switch out the memory and take out all peripheral cards. If it posts but won't boot it is likely a peripheral device - HDD, Add on Card, etc. or software - new driver, etc. Go back to last good menu in that case or just boot into safe mode.

[Deadlybrit]

I have the same problem...i go to turn it on and NOTHING......then suddenly 10 mins later it will just turn itself on?....but this doesn't happen all the time...i have to unplug both plugs and wait for about 5 mins...then plug them back in and still have to wait for about 10 mins....any possible answers???...i have done everything you said i the vid...

[alishariefm]

Hi,

Do check by opening the Power Supply to find out any capacitors are not blown this happens due to power supply of your computer.

[qx125365]

this guy kinda sounds like Ray Romano.... :D

[patricknedz]

hers what mine does, I have a laptop so its a little different, when i press the power button the power light comes on then fan spins for a few seconds and stops, I get no Bios, no dell logo no nothing, I tried using another monitor but it didnt help

[aminhama]

Hi

so all i need to do is find a screw in my mother board, or have to space it out

[650038haig]

i have a old computer that will not power on but when i wiggle the cord from the power supply that plugs into the motherboard the fans turns on for a split monument then they turn off

[cooptruman41]

if the light on motherboard is on do the motherboard work?

[jamo387]

@cooptruman41 no

[singhdeolji]

Every time i turn on the power button the cpu fan move a bit and nothing happens. the power supply and the mother board lights are on. I have already try to connect it to a new power supply SAME PROBLEM. thx.

[Marcos11754]

this is my story: i was using my computer, windows vista gateway, you know i was going on facebook talking to people. but i when i got bored i turned it off while the internet explorer web page was running. so i left it there untill it turned off.two to three hours later i went to go turn it on and nothing. Nothing!.... no power light, no fan running, no power at all like if it was dead! knocked out. i tried everything, unblugging it and plugging back on. help what should i do?!

[LeleKeOpala]

My mother board is working when I push the button but all the external plugins like the monitor and keyboard aren't turning on....they do work on other computers so everything works well....but why is it that they don't get a signal from the mother board when it is on

[StealthBumblebee]

i have a gaming rig, and, is it ok for it to go to sleep mode without any long term problems?

[hallal55]

hey bro i had vista and sleep mode worked perfect...now i upgraded to 7, 64bit when i go to sleep mode and resume the pc.....it starts up but nothing goes on display...so the only way to reboot is to shut it off through the power button which somtimes i have to press like 10 times...help?

[183729jiffy]

Helpful video. This issue just happened to me. I went out and bought a new PSU (what better excuse to upgrade =P) and that didn't do much. But I will try your tips. Thanks for the vid.

[weed219]

my computer turns on but their is no picture or screen,mouse or keybored but the CPU fan works and the other fans work to plz help.

[mwmethos]

Dang. Wish I saw this vid a couple of weeks ago before I lent the non functioning computer to a bonehead to fix, and who never returned it. Now i know why.

[johndinky]

my problem is when i turn on my pc, the psu fan, heat sink fan and casing fan are working, there is a light in motherboard, a red light press the power button but it's only blank screen, i don't know what's the problem, i already check everything, pls help....

[gogeta20]

@johndinky

Hi

When I was building my PC I intended to use my brother's motherboard. What I did was a Motherboard 'POST' test. So I had the motherboard out on a cardboard box with CPU+Heatsink, Graphics Card, Ram,Powersupply and Monitor connected. Then I jumped the 2 pin PowerConnector on the motherboard front header with a screw driver. Then I had exactly the same problem as you mentioned with fans running and motherboard LED on but the monitor screen being blank

[gogeta20]

@johndinky

I took out the graphics card and jumped the power connector again to see if the motherboard bios would detect lack of graphics card and beep but nothing happened. Then I took out the RAM and repeated the same method but nothing happened.

I then took out the CMOS battery for about 1 minute to reset the bios and place the CMOS battery back again in the motherboard. I then placed graphics card and ram again and jumped the powerconnector but again nothing happened.

[gogeta20]

@johndinky

By this time I was pretty sure that the Motherboard was 'DEAD' as all my other parts including powersupply were brand new. So I bought a brand new motherboard and repeated the POST test and it worked absolutely fine.The screen turned on and the POST screen was displayed.

So johndinky I think most probably your motherboard is 'dead'. Also is your powersupply in good shape. If not, then that could also the reason for the fault. I hope my experience has been of help to you.

[milsyambao]

I did the same things you said up to the point of restarting using metallic pin. Nothing happened. It did not even start both fans on PS and CPU. Replace motherboard. Fans are running but PC wont start... The next step, replaced the CPU. It did not start it. Will it be the memory?

[sexyred720]

computer come on but wont go pass the boot page...looked inside and everything seemed to be just fine....so what could be the problem?!

[asillynoob]

if you hit the power button an nothing happens, yet power is delievered, the motherboard is dead, nuff said

[NYballer11725]

my pc was shutting down on random 2day, due to bad ventilation, i had to clean all my fans, and the inside of my computer, and the power supply vents

[faint255]

My Pc briefly turn and turns off as soon as it starts. And do you need standoffs for a mini-itx board?

[FinalFantasyLover117]

heres something, on mine i took it apart, it there someting suspose to be touching the power button? i didnt see anything, then agian, when i push my button sometimes my keyboard buttons light up, then stops, but... not my mouse light, idk if thats any help, but message me for any ideas yea you thanks.

[SuperGameSpot]

[TheRealKittyboo]

hey, i've got a problem, i've got a vid about it.

i'd like some help possibly!!!!

[stab2killnecks]

i'm working on a hp that makes a loud beeping noise when you try turning it on. when you try turning it off it just keeps beeping. also its not booting up. any thoughts? thanks!

[liquidbook]

What was the solution? Was the problem the PSU or MB?

[sapensisback]

remove the rams 1 by 1

and try to start on your pc

[AoNiC101]

SOMEONE HELP ME PLEASE!!!

i just bought a new graphic card and new power supply, after i installed it all, i have to press the power button a few times before it turns on and when it finally turns on(Fans on, led's on) the monitor does not respond!!!! The monitor is on but the monitor DOES NOT SHOW ANYTHING!!

Help PLease, its left me scratching my head all day and night

[Johnflugelhorn]

I find it safer to remove the black lead and red lead from the power switch on the case and short those leads together,rather than mess with the motherboard terminal. I shorted the black and red leads together and the computer started. The problem was with the switch.

[bradzdestroyer]

I took a pc that had a loose heat sink to best buy, simply because it was under warrenty, i caused the problem and knew how to solve it, and it was free. They said my motherboard would have to be replaced, i should consider a new pc. I acted to browse around, then ask if they checked the cpu.. "yeah we did, but no luck" I ask if i should just buy a new motherboard "It might be cheaper to buy a new setup, motherboards are real tricky to shop for and install" they say. I took my pc and left.

[bradzdestroyer]

That was all for a report in college.

[kevingp12]

wow i should try that one day, ill secretly film it too lol!

[bradzdestroyer]

This happen to me, the problem was i had the power button wire running to the wrong pins. Im not sure of correct term.

[popoyjay09]

just reattached your wires in your disdrive xD

[adsc19876]

help my pc turns on but it doesnt display anything and makes a loud beep help pls

[bradzdestroyer]

Look up the make of your motherboard, find the beep codes.. Is it a looong beep or short? Could be loose ram, have you messed in the bios? You could try resetting the cmos? Keyboard and mouse plugged in? Graphics card burnt out? It could be alot of things, something simple or major.

[adsc19876]

fixed it now its to late :P

[technodj13]

my pc turns on but on my screen nothing appears its all connected ...

help

[ASUSM2VMXSE]

sometimes my pc wont on, more not, and now it no longer turns on... WTF

my motherboard has only light when plugged but when i hit the power SW, NOTHING HAPPENS no beep, monitor light beeps only..... ?????

[JTD19881369]

Hmmm.. My PC turns on... the fans fun but I have to manually spin the power supply fan.. as soon as I get that going the moniter flickers a white frame about every five seconds :(

[lowlux1]

i found a dell 170l 2.8 in a ditch 2 feet under water... been out there 2 to 3 weeks/

after a few hours cleaning... the power switch was not working right so i cleaned it with a spary... now i have no issues with it. there was mud in the damn CPU... looked like shit!

[Th33mporor]

it might be the power supply

my power supply died and it did just that now i ordered a new one

[mamman93]

I've just built a computer and it all works but for some reason it doesn't start up some times. So every time I have to open it to check everythings plug in even tough it is.

I think that the power switches are set wrong in the motherboard. When I turn of the computer it restarts again. When I go in sleeping mode it shuts of. lol.

[tylermoore]

Power switch cables are faulty. The switch was not designed properly. Look into getting a new starter switch. =]

[mamman93]

Don't worry I figured it out a long time ago. :)

The power LED switches was in wrong places, I checked the motherboard manual.

[angelsplayguitars]

i have a similar problem. but my comp will "turn on" but it just stays in the phase where it is booting up (fan running and such) but nothing ever comes on the monitor, AND i never hear the "BEEP" had it repaired like 3 times, and motherboard and powersuply just got replaced a few months ago. any ideas?

[mrdbzfreak]

same if u get a solution pleeezz tell me pleeez

[pikeybot]

mine the same it take 2 attempts to boot up when i click on button the fans work but no bleep when i press the button it switches off then when i press it again it boots up and bleeps...

hmmmm it only been doing this for a week..

[ManuelEscobar360]

My computer dont power on, i only change my hard drive and then when i connected the hard drive and i press the power button the pc dont turn on, i changed my power supply the an old one and the problem still...help!!!!

[818lyeannea]

ok well my pc wont turn on...i press the power button only the fan and the disc drive works and the monitor dosent show anyhting..... help

[ManuelEscobar360]

If you turn on the pc and everything turn on and the system dont boot , check if your ram memories are correctly connected or your video card is not working or the processor.

[4NEOFEAR]

Here's the thing - i changed my power supply that worked before and changed my old m.board that worked before + cpu and ram. Thing is that mother board shows power led is on and green so it's all fine with m.board and power supply. i tryed to pin power connectors but nothing, could it be that this happens becouse of hdd led not working or something? Thanks!

[slayercoolsnake]

Same here dude how do you fix it ?

[malechubby]

before my pc is just hang at no reasons at all... then suddenly it didn't work like there's no showing on my monitor, but i can hear my pc is runnnig but nothing showing on my monitor? ... please help!!

[lostsoldier1967]

Just disconnect the PSU jumper the power good lead green I think om the mother board connector and the PSU should start if not plug the HD in then try again if nothing check everything is turned on (like power bar ) or PSU switch like you said if nothing check the mother board for burnt components first if none then and only then swap PSU's cause if you don't you can fry your spare PSU bad thing to do ! note: the PSU I had worked with no load and just jumper ps-on not all PSU's can do this !

[teagobenir]

i have a problem help my pc was working perfect bu the other day ay plug mi phone in to load stuff an i got a ms that sed divice exides power limit and then frose y manualy tun my pc of and on and all i got was my fans were runing nothing else it wont star what can i do????????? plese help

[Testivaginacles]

I have a problem, I turn my computer on, the fans spin for about 3 seconds, then stop. Nothing else. What could this be? Please, I need help badly.

[sonicrushfan1]

Everything is good about my PC, but when i boot up it does not show anything on the monitor and starts beeping very hard after 10 seconds orso. Could this be the RAM? Please help PCmedianet!

[bmbbmx]

yes...either that(the RAM)the powersupply, or the motherboard, when we were testing Computers at school, the computer would beep and not show video, but after we changed the PSU, then it worked

[jamil1066]

ok well what happened with me is i was on my pc nd it crashed for 5 mins and wouldn't even restart. in the end i turned off the switch. the next day when i tried to turn it on the here the fan (i tink it is the fan) spin round but there is nothing on the screen. i no the monitor works because i tried it on my other pc. could it be my hardrive?

[utiuburself]

then how to determine the mobo is the 1 prob??is any device to make sure that mobo is completely unuseble?

[swakeem1]

would a corrupt hard drive play a roll in this too?

[tracer1024]

it would still turn on if it was yr hd

[darkwhisperdc]

by the way.... u forgot about cheking the memory modules... and it could be the cpu overheated and burned.... this are 2 major cases to when u're pc isnt booting....
