8800gt Crashing

Hey everyone, I just wanted to ask for your opinion before I go ahead and RMA my graphics card.

I have a PNY 8800Gt and it crashes when I run any 3d applications. I discovered this yesterday when trying to load the first level of Unreal Tournament III. It also crashes every time within two seconds when I scan for artifacts in ATITool; although when I just show the 3d cube it seems to handle itself ok. Also, by crash I mean it completely freezes up my computer, giving an occasional screen blink.

Anyway, this is happening just two days after I put together my new system, though I think it's just coincidence. I've got a Q6600, OCZ Titanium Ram (4gb), and a Biostar Tpower I45 motherboard for the record. I've run Prime95 for a few hours and the processor and ram seem to be alright. I've also done memtest and that checked out fine as well. I have an Ultra 600W power supply so I don't think that's the problem either.

I have also done numerous restores and driver reinstallations with the card. When the card freezes the temp is usually around 63 C so I don't think it's overheating.

So I guess my final question is, do you think it's time to RMA? And is there anything else I could try? And also, is there any possibility that something could just be wrong with the motherboard?

Thanks,
Alex

I'll give it a try. I only run Avira and it gives a notification when it comes across anything it doesn't like, but maybe it didn't tell me about something? It is always on though, so perhaps. It worked for a day or so after I installed the new drivers which is why I'm a little confused.

Thanks for the suggestion.

AlexLastName what is the 12 volt rail of the ultra psu the 8800gt takes 26 amps.if you suff internet or any thing else does it work ok.

Oh, and also, I did try the antivirus thing and that didn't do it. And now that I think about it, the card could have gotten messed up somewhere in the building process. The only game I've really been playing in the past few days was Black and White 2 until I got Unreal Tournament. So perhaps that game just wasn't pushing the card hard enough to make it crash. Just a thought though.
