Yesterday Flash updated automatically to 10.1. Since then, every first-third youtube video i watch, the screen gets completely grey, and then eiter
a) it gets back to normal after 2-3 seconds
b) the grey screen stays for about 15 seconds, and then i get a bluescreen
c) the grey screen stays for about 30 seconds, and the the computer reboots
disabling hardware acceleration didn't help.
OS is windows 7 ultimate.
Hardware: ATI HD4850, Intel E8400, P5Q Pro Motherboard.
When you write "bluescreen", do you mean BSOD (blue screen of death)? If so, what is the error code?
Have you tried updating the device drivers for your graphics/video/display adapter?
Have you tried disabling hardware acceleration?
If you use Firefox, have you tried to update to 3.6.6?
Seems that a Driver update for the GPU helped.
