Computer random restarts while playing games, is it PSU?

post #1 of 6
Thread Starter 
So, this pc is pretty new and its working fine when im not gaming, however when i play some games the pc just restarts, no BSOD, its kind of random, it mostly depends on game, sometimes it takes only 5 minutes to restart, but it can take like 1 hour to restart too.

I've replaced memory sticks and HDD, but its still restarting.

PC info:

i5 3570 (non-K version, so no OC)
Radeon HD 7850 1gb
GA-B75M-D3H
2x 4gb ram
1TB HDD Seagate
Corsair 430CX v2 (its the old version, it provides 28A on 12v rail)

Also, i've ran furmark and the pc restarted in less than 5 minutes.

though you replaced the memory i'd suggest running memtest just to make sure. but even since you are only drawing < 250 watts max that PSU may not be handling a full load, which is a bummer, you wouldn't be able to swap it out with anything else before you buy another one?

The Corsair CX is not all that great of a PSU its not very well made

Yeah it might be the PSU i think its the OCP that kicks in ort he PSU could be broken

Or something in your system could be overheating

A few days ago another user reported his CX600 got hot as all hell so you may have the same problem

I've already ran memtest and there is no errors.

I dont think its an heat issue because when i ran furmark the vga was 52 and 66C when restarted (i've ran furmark twice).

So that only leaves the PSU or maybe a faulty mobo, i dont know =/... by the way, what PSU would you recommend for this system?

Thanks for the help guys.

I had a similar problem a couple months ago. I fixed the issue by cleaning my case out with compressed air and I haven't had a problem since. It was most likely dust causing a short in one of the parts. (most likely the psu)
