I have some free time so if possible I will see if I can find anything with my capture card. I'm not hugely hopeful, as my desktops don't seem to be affected, but I do have a range of hardware available to test.
Could you list the hardware, drivers and windows version which caused you the problem? If its a laptop, does using an external monitor help? how is the external monitor connected? How long does it take for symptoms to appear?
I know a lot this information is already out there, but its scattered across a lot of threads and may be out of date.
