There are no error messages, no blue screen, just locks up. I have to reboot.Is it just locking up that you can't move your mouse etc, but no error message?
Or do you get a big blue screen or something similar?
Also how does it "unfreeze" - do you have to reboot, or does it just unlock itself after some time?
