Display goes blank
Hi.
The display always goes blank for about 3 seconds when I:
plug in a usb stick
add a second monitor - by switching a kvm attached to the second video card output
The display sometimes goes blank for about 3 seconds when I:
start a movie playing from a virtual drive or change which iso is mounted on a virtual drive.
This problem started when I installed the 64 bit version of win7 to be able to use all of my 4 gb memory, with a view to adding some more on top of that in the future. Wtih the 32 bit version there was never a problem.
I have reinstalled the driver for the video card - nvidia 7600gt - downloading the latest version, but this does not change the problem.
When I remove the video card and use the onboard vga there is no problem.
I found this quite old thread about the same kind of problem
Screen Goes Blank
but I have swapped out the memory for different memory with no change in the symptoms, and besides, the problem occured exactly when I changed from 32 to 64, so the 64 bit driver for the nvidia card seems the prime suspect.
I've done a lot of googling but I can't find anything about this kind of problem with this symptom so I don't know what to do next.
