Nothing wrong with the card. This is a known issue with XP. Instead of
hacking through the registry, what I suggest is you download a program
called "Reforce" (
http://www.pagehosting.co.uk/rf/) which will allow you to
modify your monitor's profile. What the program does is fool the computer
into thinking that the lowest refresh rate your monitor will run is the one
you want it to run at - be it 75Hz, 85Hz, 100Hz, etc.
When you load it up the program displays a list of all possible resolutions
and the maximum refresh rate supported by your monitor profile. Just change
any that are too high to a lower value (like if it says 150Hz at 640x480 you
might want to make that 100Hz instead) then apply and reboot. Another tip -
go to Display Properties - Settings - Advanced - Monitor and make sure the
"Hide modes that this monitor cannot display" option is ticked, otherwise
this may not work.
This forces your refresh rate in all 2D and 3D applications. Note that the
number you enter has to be supported by the video driver - so don't enter
odd numbers like "96Hz", stick with what you know is an option like 85Hz,
90Hz, 100Hz, etc.
This has worked well for me for over a year...
