X1900XTX NOT WORKING?

[Animebando]

I have a problem. I just recently bought an X1900XTX and installed it in my system. Problem #1... I had to run windows in safe mode to install the drivers. After that, I had VPU crashes in Oblivion, but it worked fine on all other games. Problem #2... one day I turned on the computer and the Ati utility said that there was no valid driver installed... so I attempted to reinstall it (both in normal and in safe modes), but it constantly came up with an error. Something like "No valid driver found".
So... If anyone knows what is wrong PLEASE help me. Reinstalling Windows is the only other thing I can think of to possibly fix this.

My system:
ASRock 939 Dual
Athlon 64 3700+
1GB PC3200
Radeon X1900XTX
Windows XP Pro

What's the power supply?

 

[waylander]

Yep that would be my question too... those GTX (NVidia) and XTX (ATI) are power hogs...

A ThermalTake 430 W TruePower.... That is just a temporary though, Ill be getting an Antec 500W soon. Would that really explain the driver issue though?

Okay, I'm getting my new power supply tomorrow. The Antec SmartPower 2.0 500 Watt. If this doesnt fix things, does anyone have another suggestion?

Thermaltake doesn't make TruePower PSUs; those are made by Antec. Are you, by any chance, talking about the TR2 430W? I own that PSU, and it only has like 19 amps on the 12V rail, which is not enough for an X1900XTX. I suggest that you get an Antec TruePower TPII 550W PSU.
