Everytime I go on my computer the screen goes black for like 2 seconds and goes back to normal and it does it agen like every 5 minutes to an hour! Sometimes when Im playing an RPG game or when I talk to friends on AIM. It goes black constantly! And on some days it wouldnt go black at all but then it would do it again the next day! Blinking black on and off! I dont know why it does this! And I have tried rebooting the computer....that didnt work....so I tried to unplug the monitor and plug it back and it STILL does it! Is it because of my internet connection or does it hav nothing to do with it because i use a wireless router thing and i have a flat screen monitor n i use a dell O.o I dont know! Someone please help me on what I should do to stop it! Thank you!
