i have been having this problem for a month now. Mostly whenever i power on my computer, it shows the screen and then goes blank and it keeps on doing this again and again. everything is functioning fine in the background except the screen. To resolve the problem, i keep on shutting it off and starting it again until the blank screens are gone. but i was wondering if there could be another way to fix this problem? also i use windows xp and dell. (PC). oh and also the computer use to function well before this problem came.
