Hi

A customer of mine have random and rare shutdown on his PC. The PC shutdown instantly, do not restart and do not have BSOD. The other equipment in his house do not lose power, light did not dim at all. It happen 2 to 3 time a month. I have changed his PSU but the problem still happen. Have you already experienced "invisible micro outage" that would make a PC to shutdown ?

I have also done a panoply of test, including hardware test (prime95, memtest, hitachi fitness, pcmark05), virus check, system file check, bios update. The box have enough ventilation too (2 x 120mm front/back).

I would pull the motherboard out, and make sure nothing is coming in contact with the motherboard back and the backplate and causing a short.

Thanks. It was finally BSOD. He first told me the computer was staying off, then he just changed his version and told me it was restarting. Looked at minidumps and it's probably caused by Avast.

For the replacement of Avast, you should try Microsoft Security Essentials.

glad you got it figured out. BSODs are weird sometimes, often Ive had them where it will BSOD, but the computer will crash before the BSOD actually appear, while the next time it does. It drives me crazy when stuff like that happens, makes diagnosis extremely difficult and time consuming because you have to convince the computer to crash more then once, and if its not your computer well lol.
