I have been having a major problem with my pc. I thought it was my video card but I swapped it and still have the problems. The screen flickers alot, everything is real bright on the monitor. I played with display settings, no help. I hooked the monitor up to another computer and it worked fine. All this started after a lightning storm, I have a surge protector but the storm knocked out power. Its not the monitor or video card what the heck can be causing the flicker and brightness?
