X1800XT Problems

[Yohan_The_Brave]

Ok I just put together this system last night. Everything boots up and seems to run fine. I installed oblivion (excited to see it with all the stuff turned on) and it was great for about 20 seconds then a bunch of weird artifacts started to appear. If I exited right away they stop and windows looks fine. If I keep going my screen goes black and the monitor gets no signal until I restart. I'll be updating the drivers tonight, but something tells me that's not going to fix my problem. I know I can try more cooling on the card but it just doesn't seem to be that hot. Maybe the power supply isn't enough? I've included the specs for it too. Maybe someone can tell me if it's ok or has some other ideas I can try.

Thanks.

What drivers did you use for the gcard?

I'm using the newest ones 6.4 I think. Last night I tried putting a pci fan right under the card. It seemed to last a little longer before the artifacts showed up but in the end I'm still having problems. Anyone have any ideas?
