I updated the video card drivers, nforce 4 chipset drivers and i see no difference. I wasnt able to update the bios cuz when i use Asus update to do it, it doesnt do anything and my cpu usage goes 100% for like 15 min and doesnt do anything. Some winflash.exe uses it but it never finishes, it seems to be running in the background. Anyways im doing 3dmark 05 right now. We'll see. How do u know if you have bad memory?
