So I was playing a game on my computer last night, and the moniter starts to flicker, then turns off. I then exit out of the game and everythings fine, so I leave the computer to brush my teeth come back, and the moniter's blank again. I turned it off, then replugged the moniters power plug and video wire back, turned the computer on, got picture for 5 minutes before it blinked, then went blank. I know its not my monitor because I tried 2 other monitors and I got the same problem. My video card is a Nvidia GeForce 5700LE. I took it out, and plugged the cord from the monitor to use the integrated video card on my motherboard, and now I have picture. Does anybody know what the problem is? Thanks.
