David,
You most likely have problem in driver for your video acquisiton card or problem with hardware itself.
Since you neeed more that 5, 30, 60 minutes time for problem to reocur then it is hardly related to any MS driver or BIOS settings
for that matter, sorry :-(
My wild guess about your problem is that this is IRQ related problem. Since your driver relly on IRQ to grab each frame or even part
of line, in case that this IRQ is not handled for some reason and you do not have some timer event in driver to handle this
sitruation then you will be frozen untill next IRQ arive. Depending on your card settings this IRQ might never arrive.
When you use keyboard or mouse there is a chance that IRQ is shared between then and your card so this could kick you driver so
start working again.
One things to make sure though that might cause yu a lot of time effort to diagnose. Make sure that your card do not share IRQ with
graphic card. You must do that from running XPe not from BIOS.
This is one of major reasaons why you might see this behaviour.
Regards,
Slobodan
