i just got a new monitor and its kinda doing the same thing as my old one. it will turn black for 1 sec then come up again. for my old monitor i knew it was doing that b/c it was old and etc. But I don';t know why my new one is doing it? ( BTW its running @ 1024 x 768 @ 72hz) It said it recommended 800x600 @ 80mhz but w/e. I hope I didn't put the refresh rate too high, im 99% sure i didn't so i think the problem is the graphics card or mobo? probably the mobo b/c its really gay and has been doing freaky things lately!!! as you know from my other thread i will be definitely geting a new mobo soon!!! Give me any info if you know any.
