Working on a friends HP Model# G60-8200mg, having a problem with video drivers. Can get system to work just fine with standard vga drivers. The minute I install Nvidia drivers from Hp, Microsoft, and Nvidia, I tried all because they all recommend different versions. None work, system starts, then desktop, then freeze. Checked and found there is always a problem with memory at memory range C0000000-C0FFFFFF conflict. The Nvidia drivers all use that range. VGA drivers use a different range. I am stumped at this point.
