After a couple hours of use I get strange issue. The start menu jumps up to the top of the screen (but is not really there). Parts of background programs jump over foreground programs. The right click menu goes all black. Control panel will not open etc etc.

Tried 3 different sets of graphics drivers
Two different graphics cards (one Nvidia Geforce 6800, the other a Geforce 2 GTS)
A different older copy of XP on a different partition
Did a mem test

Problem still present

Are you overclocking anything? Check the BIOS for any manual settings. Or try a default setting to make sure.
What does DXdiag show?

Thanks for the suggestions people. I have done a little more testing to help rule things out.

Its not a monitor issue (I did suspect it once). The reason I say this is that its not just a graphics issue. An example is when I try to shut the machine down, the shutdown button does not appear properly. All I see is its outline. If I click where it should be the machine does nothing. So its more than just not showing things properly.

I believe I have traced the issue down to an accessibility control I am using. Its called "mousekeys" and is an in built control in Windows XP that allows you to use the keypad as your mouse. I am having to use this due to RSI in my fingers that prevent me from clicking a lot. I have no issue moving the mouse with my right hand, I just use my left hand to press the '5' button on the keypad for a left click.

It would appear that after a few hours use of mousekeys I get this issue. The issue is present on two different XP installations on this machine. Anyone know of a replacement for the program, or a bug fix? I've searched the web but I'm not getting anything so far.
