I have a 2-year-old card. Every time I turn the computer on after being off for 4 hours or more the 32" LG monitor flickers, the screen changes size and speaker sound. This goes on for about 5 minutes. After the computer go to sleep for over 4 hours the same thing happens. If the computer is restarted no problem. I have updated the drivers with no change. This problem stared about two and half months ago.
Any suggestions?
