Installing SP2 completely screwed up my video drivers. I have an Asus A7N8X 2.0 Deluxe motherboard with an Asus brand Geforce4 Ti 4200 AGP8x. At first, only minutes after installing SP2, I received a blue screen error with the affected file being nv4_disp.dll. I quickly checked Asus and Nvidia website for updated drivers. After installing updated video driver, my display has deteriorated with pixel dots all over. I reverted back to my original video driver version which helped reduce the numerous pixel dots but problem persists. I even upgraded the nForce driver set for the motherboard as well as the Bios version to no avail. Finally, I completely rebuilt my system with Windows XP including SP2 and to my disbelief, the problem remains. Even during bootup POST, the screen has messed up display with colored vertical bars obscuring the text. I refuse to believe that my hardware is failing since this appears to be driver related. Anyone experience anything like this?
