I get Stop (BSOD) errors with reference to the video card drivers, three so far in relation to the main driver, one in relation to the Mini VDD driver, and 1 with no driver listed. 5 errors are as follows: nv4_disp.dll address BFA6AE83 base at BF9D4000 Date stamp 44dd4897.

Processor Type and Speed: Athlon X2 dual core 3800+ (CPU AMD|A64 X2 3800+ AM2 2x512K) System Ram: 1Gx2 CORSAIR TWIN2X2048-6400 System Bios Version: m55sli-s4_f4 Driver Version: Forceware 91.47 (6.14.0010.9147) Operating System: Windows XP Power Supply: PSU ENERMAX | ELT500AWT 500W RT (22 Amps on the 12 volt rail) Comments: If I leave my computer on during the night seems like 8 hours+ of the computer being on is when I get my blue screen Stop errors. Seems like I only get blue screen stop errors when I am running a game using the video card. When I am not running the game and leave the computer on for extended periods my computer just simply freezes and gives me no blue error. My dxdiag says that the approx. total memory is 512 MB. I thought my video card was supposed to be 1 Gig. Does this mean my motherboard cannot handle my video card because it is top of the line? Also I read in the manual for the video card that it requires a minimum of 450W. My power supply is 500W (22 Amps on the 12 volt rail). Could that be a problem? The memory that I have is on my current motherboard's list of compatibility, but it is not the recommended memory. I ran memory scans on my memory for more than 8 hours straight. No errors. If it is a motherboard problem, which I assume it is, I am going to buy a different one. Are there any motherboards you could recommend for my setup? If not maybe more change is needed. I just want to have a stable computer.
