Hi,

I got a problem with my PC I got 1 year ago. Though it worked very well for like 3 months, it then started to have strange random behaviours :

- it first started not to boot (pressing the power button simply had no effect although the lights inside de case was all green (GPU/MOBO/...)), until i unplug the alim cable, wait for all lights turns off and plug it again.

- a few time later, it sometimes shutdown and reboot for apparently no reason (error message in windows event was only "kernel shutdown")

- finally at about 7 months, it brutally shutdown and the GPU was dead as well as the MOBO (according to the assembler who made the PC).

Both GPU and MOBO been replaced but now, about 4 months after they replaced it, the same behaviour started again.

I ran OCCT, for 8 hours without any trouble, also checked for problems (like conflicts or something) but i found absolutely nothing.

The PC is protected by UPS and do not show any sign of problem on use (like brutal fps drop or blackscreen or anything).

What could be the problem ? I have no idea.

You could check if there's an update for the bios/uefi and apply it or otherwise,

Well, for additional informations :

My Pc shut down brutally while playing a game (Diablo 3), then it automatically tried to reboot but get locked in the bios with an error message i don't exactly remember implying a power surge.

I checked values in the bios and my 3.3V was in red (at 3.6XX) which then dropped to 3.4/3.3.

Is it possible that my PSU is kinda bad (it's supposed to be only 1 year old) and causes a surge which trigger a mobo security ?


Then should i really change my PSU or is it beacuse of a bad setup in the mobo (i actually never tried to overclocked anything).

Thanks.
