Did you forget something?

"WARNING! CMOS BATTERY IS LOW!"

[mbrock5532]

@HoneycombAgent Nope, it wasn't the CMOS battery. The voltage was fine.

Well Before anything else or what I mentioned Just read what other said under your post! None of them said "Button issue". I'm a certified Tech and I know that It can't be button at all. But Please don't take anything personally I just said silly but doesn't mean that way! You did a wonderful job and at least tried to help others which I really admire!

[mbrock5532]

@sa2010ism No problem... I learned long ago that just because I never observed something, or something didn't make sense to me, didn't mean it doesn't happen! As soon as we think we've seen it all, we get stumped. The only reason this wasn't fixable was only because of the way the Shuttle integrates the reset button to where replacing it requires a board to be replaced that is expensive and when you add the labor expense, it doesn't make financial sense for the customer to have it fixed.

I really don't like this video. The reset signal is on as to avoid supply to CPU. It happens When your Bios is not detecting CPU. Sometimes it happens when you have unplugged the Jumper for clear Cmos. I have seen the same thing when CPU is not getting Vcore. I have never seen that buttons cause such issue in any PC. They just fail to work. Oh you're so silly!

[mbrock5532]

@sa2010ism Well, silly though you may think I am, it was the problem and none of what you mentioned was the problem. I guess the lesson is that just because YOU haven't seen it doesn't mean it doesn't exist.

might want to check the mainboard 3v battery if its dead no bios right?

This video really helped me to understand the post test card. and i like how u had an issue that didnt allow the post numbers to come up. i would have been lost if i was in that situation so it was good to learn this. Thanks for this video.

Hello There have More tools can help us find problems like the card

[mbrock5532]

@theleMBeleht I'm very familiar the null method, but in less time than it takes to strip everything down, I can insert the card without removing everything. It works both ways, but I like the speed increase the card gives and it keeps the cost down for my clients. I can also do it at their site and get an idea on the spot. The card is just another tool and some people will like it (me, and others won't (you)!

[mbrock5532]

@theleMBeleht Well, I suppose if you're fortunate to have every type of CPU in stock, every type of RAM, video card, hard drive, BIOS and anything else that could go wrong on the computer on hand that you can pull things out, you're right. How about if one component took out another and when you replace the zapped component, it gets taken out too? Most people don't have that many parts around in order to do the trial and error method. I'm glad you do - I'm envious!!!

hey i had this too, but the problem was my Bios is failed.. so i buyed a new motherboard and it worked fine!

[mbrock5532]

@Marfprojects The card actually will detect and let you know if the BIOS is the problem, so it helps in that respect as well.

[Marfprojects]

@mbrock5532 I did not have that card ... in the Netherlands because they are not everywhere for SALE. and there was a shop there but I have over 230 Killometer (142.92 miles) and I had no feel for it all to drive. Well the motherboard was very pretty old so I had just bought a new one!

[susanhtinha]

Hey guy, it's a helpful and explained video.

[mikeyw8187]

i actually just ran into a computer with this problem. all that was wrong was the power/reset plug wasn't all the way in.

[MrBettertimes]

Thank you.I am new to IT and I use these videos on this site to help me understand those concepts which are essential to becoming a good tech.Before discovering your video, I reviewed many nonsense videos without any dialogue, or comments so thank you again for providing a thorough instructive well done video about PC cards as a diagnostic aid to troubleshooting computers.

Help me I have the same card I got this code 0d01

[rstrickland20]

Just seems odd that you would have to replace the ENTIRE motherboard versus changing components :/ Not judging just wondering for my own experience.

[mbrock5532]

@rstrickland20 - It ended up being a defective CPU socket. Never had THAT one before! They sent me a new one, and everything was fine, using all the same components.

[trufflemonsterify]

@mbrock5532 they sent a new motherboard and everything then worked fine?

[mbrock5532]

@rstrickland20 It depends on the motherboard - some have so much onboard that you can't replace the part without replacing the motherboard. Other times, it may be less expensive to replace the motherboard than fixing something. As a hobbyist, you can take the time to determine the exact component that is causing the problem, and then take the time to fix it. If you're charging someone for your work, your charge to find the exact problem is more expensive than replacing something.

Have you tried resetting the BIOS?
