Hello. This is my first time on this forum so please let me know if i'm doing anything wrong. My screen normally flickers on and off on start up, but today its been going all day! I cant play minecraft with out my monitor spazing out. but if I go away for a few minutes, it stops. Its like my pc "knows" i'm there. and it starts flickering again just to piss me off... I had tried to install a new graphics card, but it wouldn't read! Please help!
