Hi there.

I'm an IT technician, and through all my 7 years in this profession, I always had the worst problems happening with my own computers. And this time it wasn't different.

Last week I got a complete Desktop, and I proceeded as I always do:
I cleaned it, checked all the voltages and temperatures, and runned several tests, including memory, CPU, chipset, and graphic card tests. Everything was ok.

Then, out of nothing, it stopped booting. Right when I was using it. It suffered no physical impact of electrical surge. The USB ports are not being energized anymore, the video output gives no signal, nothing. It had no problems before, it worked fine during this week. It also never stopped working before I got it.

I cleaned the CMOS memory, but it didn't come back. I tested changing the memory on the slots, testing all the combinations, and also tried with two CPU's, the original and a Pentium 4 I have here. Nothing works.

I checked all the voltages on the pins with it running, everything is normal. No chip on the motherboard is either cold or overheating, everything is getting just as warm as it should get, but nothing works.

I checked for blown capacitors, damages on the circuits, loose solder joints, nothing is wrong at all.

So, any ideas?

Computer information:

Intel Desktop Board DG31PR motherboard
Core 2 Duo processor
Two 1GB Kingston DDR2 667Mhz RAM memory sticks
500W 24-pin ATX power supply

Hi, what were you doing when it failed? anything intensive?
Did the whole system turn off or did it keep going without outputting anything?

How old is the system and where did you get it from (second hand?)
