Is this a graphics card issue?

When I start up my P.C. it runs fine for awhile then the mouse stops working and then everything gets choppy (sound and display) then freezes. If I restart it, it then works fine (just doesnt crash again). What does that sound like? Also, it seems to think I want to enable multi-displays but I was pretty sure that's only if you actually have more than one monitor... Help!

maybe your system file corrupted so you might want to use restore point or simply reformat the disk. have you installed any program before this problem occur?

other possible problem might come from overheating issue since you're running SLI (since SLI setup produce more heat than single setup).

I'm pretty sure I've tried running each individually before and had the same problem, so I dont think its overheating, but It was like 6 months ago. If I didn't have to leave for work I'd try it again right now. Oh well I'll just do it when I return, but I appreciate the prompt response, I think this is my new favorite forum :p

I just read from one source that you need 400w for ONE 7900... can you reccommend any cheap but ofc awesome PSU's? Think ebay would be a good bet? Darn I gtg to work I'll try and log on from there, but again ty all for the help
 
i have a friend running single 7900GS. from his experience even cheap 500w psu are not up to the task. so get some good quality psu and save yourself from trouble. since you're running on SLI setup you may want to consider 600w and above psu.

you also may want to check your card individually to make sure your card is not faulty.
 
Ouch, that's an Apevia Turbolink PSU.
Depending on your budget, a single HD4670 may offer better performance than your pair of 7900GS cards in SLI (it's five tiers higher than just one). It will also sip power (no PCIE connector needed), and lower the heat in your case.
You could run up to a HD4850 on an Antec Earthwatts 380 PSU. Assuming your instability does not continue (likely due to damage from that PSU sending who-knows-what sort of voltages through each time as it overloaded), check out the Antec Truepower New 550W PSU for the two cards you have.

So I just grabbed a TX850 from corsair for $99 bucks not too bad, installed it and now i realized there is no connector for the smaller four pin conncection on the motherboard, (i think its the 12v auxillory connector).
Gonna see if it powers on w/o the blue light flashing on front of case, And w/o the four pin connector.
So, ya it powers on, but monitor not showing any picture...
Am I blind does it have the 4 pin connector???

Haha you are right mousemonkey, I just returned to post that it appears to be an eight pin.
Good news, SLI enabled w/o a hitch!
Now to do some further testing via BF2's Project Reality. Very demanding app this game is, so it should be a decent test. Be back in a few hours w/ results.

Well graphics look great like they should w/ SLI properly enabled, but I think I now have an overheating issue. Ran for about an hour and then everything powered off, had to wait a few minutes to restart, ran for about 15 seconds then powered off again. I'm afraid to boot up again. Is this an overheating issue now w/ the dual GPU's and new PSU?
