problem with the asus A7M266

Hi, I am having a problem with either my video adapter, my power supply and or my motherboard .I already e-mailed AMD and Asus about this and AMD said that I should try out a new power supply. Asus said that I need to install the latest drivers. The problem that I am having, is that every time I go to a game(Microsoft Midtown Madness, while loading) or something that has 3-dimensional rendering(screen saver after 2 min or so) in it will lockup and it will, sometimes, but rarely, restart automatically. It only started happening after I installed that driver for the AMD 761 chipset and it never did that before. I can understand why it is the power supply because the driver is utilizing the full power of the chipset, processor, memory bus and AGP. The processor itself uses 110 watts peak! 70w constant. The driver that I used was the "Windows ME AGP driver", and I believe that driver is for the "AMD 761- CPU to AGP controller". My processor is not overclocked, neither is my video card. My processor is running at 92 degrees F (1.5 volts, tested@1.3v and passed) so that isn't the problem. if I leave the driver out will it affect my system performance, does anyone have the same problem If so have you fixed it yet and can you tell me how to fix it
thanks,

Marc
