    Hi, I am using XP pro. when I boot up I get a message saying


    Error loading C:\windows\system32\NvCpl.dll
    Invalid access to memory location

    I thought this may have been a video card problem, so I downloaded the newest drivers from Nvidia for my geforce4 420 pci card. but I still get the same error. my system is also rebooting while playing some different online games that I and other's in my family play.

    Some other info that may help you help me is that I had a virus a week ago, it deleted some windows files on win98se. I tried reinstalling windows and it said the same files were missing, so I was going to do a low level format on the hard drive, but it would not complete because it said my hard drive was messed up and I needed to replace it... I bought a new HD and am getting the same errors with Win98se, and the above stated error with WinXP. a friend told me it may be a CMOS virus, how would I get rid of it if that is the trouble?

    NvCpl.dll intializes the clock and memory settings on nVidia based graphics cards. Disable if you overclock your card. That's all I know.
