Your thermaltake psu doesnt cut it. DC OUTPUT +3.3V +5V +12V1 +12V2 -12V +5VSB
Max Output Current 30A 28A 14A 15A 0.8A 3A
Thats only 14 and 15 amps per rail, not enuff for your gfx card. I have a 1900xt 512 and a 8800GTS, and they need around 20 amps per rail and at least 30 combined. Thats your problem. Id get a new psu or it could take out your whole system

agree with the above, don't risk it, turn your computer off and order a new psu, get a hiper type m 580W, simple, cheap, effective, can also power and 8800gts if you ever want to upgrade, simple do it and you problem will be solved, end of. It probably only showed up now because the psu can't handle full stress anymore.

im not a big fan of hiper. but still the 580 watt version would get you moving along just fine.

Im more of a tagan and silverstone person :roll: :lol:

I basically agree with the other posters that your psu is too small, though I would recommend something in the 600wt class; Silverstone, Enermax, Thermaltake, etc.

One other possibility is that the video card is failing. I say this because I have a Sapphire 1900 XTX that failed and produced similar problems. I had tried upgrading my psu, but that didn't help. The Vram on the card had cooked. So, first try a bigger psu, but if that doesn't help, try to RMA the video card.

I am currently having about the same problem so I will piggyback this post. I have an Asus A8N5X motherboard and an Nvidia GeForce 7900GS. My computer black screens while playing BF2. Purchased a new power supply (Enermax Liberty 500 watt) with no help. Tried different ram, tried new hard drives, new cables, reformatted twice, ram memtest, ran WD diagnostic tools, different video card drivers, nothing helped. Temps are all good, CPU not over 65c and video card not over 65c. Usually shuts off after an hour or so. Sometimes three times a day, and sometimes not for two days. I am confused. Running a slight overclock with CPU and video card, but have set everything to default and still black screens.

Maybe motherboard, cpu, or video card going bad? Possible still a bad power supply?
