I have a xfx 7900 gt video card that was causing video problems with my computer. I RMA'd it for another one but it is giving me the same problem I was wondering if it could be my power suppy not putting out enough power.
Here is my set-up Athlonxp 3500 wd 10,00rpm hd, wd 7200rpm hd, sony dvd
burner, sony cd recorder, asus sli premium motherboard, 2 gigs memory. My power supply is a Thermeltake 480 watt ps ( It is about 2 years old) It has 2 fans on it, one for colling the ps and not sure what the other fan does maybe
cools the cpu. I know this is long winded but Im getting ready to rma my 3rd xfx7900gt video card. Is it the card or not enough power. ?

If you have only one video card and don't plan on getting a second anytime soon, a PSU with 28A on the +12v will do fine. My 7900GTX runs on a 500W Ultra with this rating and it runs perfectly stable 24/7.

Could be anything, that cpu is really outdatted and could be bottlenecking the system. It could be power, but many users are even able to run 4 video csrds off a 480 psu. I think that psu is more then enough power for your system. Make sure your mboard bios are up to date as well as all other system drivers.

Exactly what kind of problems? Artifacting, crashes? Know any one with a psu laying around you could try? Before you go throught that hassle again?

Thx for all the help, I will look into getting another power supply. I can't believe that my second video card is bad, but I have been reading alot about the 7900gt cards crashing and texture problems...

It is very possable that your power supply is causeing your problems ,I would get a bigger power supply that puts out more amps on the 12v rail before I would rma. it.

No it's all the 7900's, and I think it's his psu not meeting the ampage.
