My computer restarts when I play 3D games

[Zeroxoz]

Ok so I have a new computer that i built and it worked fine before my PSU 750 watt cooler master 700B "blew up" then i got this new Ultra X3 850 watt PSU and now when i play games after like 1-3 min of play my comp just restarts i tried turning off SLI but that wasn't it so now im stuck im quite computer savvy so ive tried everything i know to fix it on the software side but i don't know if it could be a hardware problem i know the prob is not overheating it could be some f-d up driver problem that i don't know about but any way here are my specs

u have 1 or 2 vga ? that seems like a crappy psu to be honest. u should have gone with corsair or cooler master again. try with another psu.

what do u mean 1 or two vga? but to answer u my gfx cards sulply me with 4 seperate dvi and the last cooler master i got sucked as i explained and after it blew up i started to have these probs

The only thing that you haven't added is; cpu, gfx and chipset temps.

This sounds like hardware running hot and therefore unstable.

Seeing that it's an Intel cpu - I would look at cpu-temperature first.

*EDIT* I just read your post again - sorry didn't see your remark on temps. not being the the problem. Are you absolutely sure on this?

 

[Zeroxoz]

ya ive dLd like all possible programs and put a thermometer in there just to be absolutly shure

btw i read this other post with same prob this guy had his GPUs on 6-pin to 6-pin PCI-E then he swaped that for a 6-pin PCI-E to split 4-pin molex and that fixed it so i tried that and it no longer shutdown and restarted it just froze. there are like two evenly spaced flickers 5 secs apart then small freze then perma freze if i close the game before the big freze there is no big freze which is interesting but other games still do the shutdown such as TF2 and LOL and HON lol and hon take a while to do that tho like say 5 min after a game is joined
(the game that im using for the bench mark for this problem is demigod )

 

[Zeroxoz]

OK this has gone way too far i just opened up Windows Mediacenter and it did the shutdown and restart after like 1 min this is no longer just a game prob what the F is going on?!?!?!

A reboot during 3D games sounds like PSU problems.

not just games media center did it too

If it was my own machine 1st thing I would try would be a new PSU, the problem you are having seems concurrent with not having enough ampage output to the pci-e rails connected to the VGA cards.

Other than that try testing / replacing your ram maybe, have had a few machines I have fixed with similar issues and that was always the 2 main problems.

 

[Zeroxoz]

i just got this so i dont know ill try at my friends

 

[pcworm]

try taking one of the GFX's out,then the other,see if the problom presists,see if the problom is solved..
it was'nt really clear,how are your graphic cards connected to the PSU again?
