Hello, i'm experiencing a problem with my monitor or pc, probably pc. So my screen sometimes goes black for 2-3 sec.
it's actually not so annoying since it doesn't happen often but would be cool to fix it finally. Also very rarely my monitor freezes and i have to restart my pc, i think it's something to do with my os since this problem started occurring when i upgraded from wind xp to wind 7, havent tried reinstalling wind but will probably do it soon.
I thought it maybe is a video card problem but it's not, cuz when the problem started appearing i used my integrated video card, so i bought an
dedicated video card 1 month ago and still i get this black screen, so i'm thinking it's the os problem cuz when i had wind xp, it was all fine
