Dead computer (Possibly due to overheating)

[ddperez]

Hi everyone,

I already have my computer for about a year now. It normally works when I have it run continuously for about 2 days because I am running several simulation tasks. I normally just let the computer run without interruption until it finishes its task. Before I send another computer simulation, I give it a rest for about 12 hours (the computer is turned off). However, a day ago, I discovered that my computer just turned off without me sending it for a shut down. Unfortunately, I can no longer turn it on... No response from the PSU, its fan not running, CPU fan does not work, the switch does not light up!

I have Intel for my processor and Asrock for my motherboard. I replaced the PSU but I can't seem to make the computer system work. I removed the RAM, HD, DVD and tested the PSU/CPU/Motherboard system, still it does not work. I forgot to remove the Video card so its actually the PSU/CPU/Motherboard/Videocard that I have tested. I suspect that Video card should not be blamed since the tasks (numerical computations) are not video-intensive nor did I call any routines that involve the video.

The CPU fan is not moving and I read somewhere that if this is the case for a "dead" desktop then it is a problem with the motherboard. Is this true? I hope so because the CPU is expensive. Are there other ways I can pin down whether the CPU or the motherboard is the problem? Thanks.

try removing the motherboard battery,leave it out overnight then put back in and try,if that fails it could be faulty motherboard

It can be any of the mb/psu/cpu parts. Did you save your old psu? You can test it with a paper clip. Just jumper the green wire (there should only be one) to a black wire and it should turn on. Test your new one as well.

as for the motherboard/cpu. the only way I know of is to try it on another compatible system. Otherwise it is a gamble on what is wrong. Maybe a local shop can test your cpu for you on a known working mb. Just pop out the cpu and take it down.

if you verify the old PSU is bad, it could have taken out everything, even the ram.

I actually had the exact same issue happen to me a few years back and it turned out to be the CPU.

btw. what cpu/mb do you have exactly?

Luck

ps, what makes you think it overheated? Did it always run hot? What it very dusty and dirty when you opened the case?
