The problem is suddenly without warning my screen will freeze then pixels will become out of place so the majority of the screen has patches of chess board squares with what ever was no the screen. Then rapidly after that the screen blinks rapidly and the computer makes noises beep beep beep. After I restart the patches a usually still there and I will go to safe mode where eventually the desktop image is restored and the system is back to normal. This only happens maybe about 1 a month or shorter for at most 2 days in a row or once in a day ,but I wonder encounter it again and unable to replicate the problem. I have left my video card running at 100% all the time ,but this does not seem to change the problem. Recently it was quite hot outside and my video card got very hot ,but today is quite cool and the problem occurred randomly though the video card is much cooler than usual. I don't think it is the video card since my whole computer freezes and I have to do a hard reboot.
