Ok, I have had my ABIT board for over a year, and was running an older GeForce 5200 without problems. I wanted to upgrade, but ever since I have installed the new card, the system will go to a black screen, and sometimes will reboot. (this usually happens when playing WoW, but has happened once or twice on the system itself). I have reinstalled WinXP, replaced the power supply, replaced hard drive, updated CMOS, downloaded the new driver dated 9-2-05 for the 6600, and even tried a new VT7 motherboard... nothing. I have done several virus scans (using Norton 2005) and spyware scans (using Spybot) but no dice. I have 1G of RAM, and a Pentium 4 2.4 Ghz CPU, with VIA chipset. This is about to make me go crazy. Is the VT7 just too old for the 6600?
