I have an Asus GeForce (V6600 to be exact) and it comes with a program called Smart Doctor. BTW people, I figured out what the problem was. Only some of my hard drives (I have 4, don''t even ask why ) were being detected when I had the card plugged in. Thanks to all who responded. Anyway, Smart Doctor detects an error. Here it is: "Your VGA card voltage 3.3 is out of safe bound, which means your motherboard doesn''t supply with reliable 3.3 voltage" (it is at 2.61V). How can I fix this problem because I think it is the reason my card does not work with any 3D games. Can I just buy a new power supply, or do I have to buy a new motherboard? Thanks. -e

What is your power supply rated at (250 Watts, 300 Watts, etc.)?

The early GeForce 256 cards are known as voltage-hungry boards and if your power supply is too weak to feed your whole computer (4 hard drives!), then that could be a problem.

If you''re really having a hard time my suggestion would be to strip the system down to a minimum (e.g. 1 hard drive, no sound card, no DVD player, etc.) and try this bare-bones setup with your GeForce. At the very least, SmartDoctor will give you a different error. If it works, add one device back at a time until you get an error.

Good Luck.

Graylien: I tried that and it only raised the 3.3V by .2V, still way below the safe threshold. Here is my question: Is this problem caused by a faulty power supply, or a faulty motherboard.

I believe this lack of power is what is causing my computer to crash in 3D games. Actually, the card works in these games up until the 3D graphics get intensive. For example: It works with the title screen in Quake 3: Arena, but crashes when I try to start a game. It works with simple OpenGL 3D apps, but when I run TreeMark, it crashes.

Again, any help would be appreciated. Thanks.

Oh, BTW, my power supply is 250W.

You can buy a guage that could see if the power supply is operating correctly.
