Solved Computer..Crash(kind of) while playing world of tanks. (troubleshoot)

Hey
So I just played world of tanks.
I load in and the game starts, i move around for about for a minute as usual, suddenly sound to my USB Headphones is cut and my monitor says "No connection found, entering sleep mode". THen i tought what the hell and restarted my monitor (didn't notice the absense of sound yet) Still the same. I waited for a little bit, then looked at the lights on my PC, none of them were showing a sign of life. (Power & HDD Activity lights) altrought my fans were still spinning. Then I restarted my PC by holding the power button down and booted into windows right away, no error logs or anything that i can see. No BSOD. Just like a death.
I suspect motherboard/PSU error, what do you think?

Yeah, that sounds like PSU failing... I would swap in a better quality PSU, ASAP.
I guess I'd a little bit higher on the watts too, 550/600w one.

Visit jonnyguru.com for some good info and reviews of PSUs so you have a reasonable idea what to buy.

If it was motherboard it wouldn't have rebooted .

My last major failure: My last motherboard broke in the middle of playing a stressful MMO, on release day of Rift, and I was playing a different MMO during Rift update, LOL! [my bad luck]

Initially thought it was PSU, but it was the motherboard, was 7 hrs later when I was finally back up running, I had bought all the parts at a local Fry's, but was 2 round trips to get the right diagnosis/parts complete.
Fond memories... :sarc:
