Alright, so i'm facing this problem for a while now probably 3 weeks or so, whenever I press the power button of my system unit, the light shows up, all the fans start spinning, no error beeps, but there is no video on the monitor. However, i do hear the "ting tong" sound of windows 7 via the speakers which means that the windows boots up but there is no video on the monitor. I checked the monitor on another good working computer and it seemed to work fine. However, if i power the system unit ON and OFF for 2 to 3 times, the video comes up on screen when the boot process initiates. Once the video comes onto the monitor, it works flawlessly. I tried cleaning all the peripherals of the system unit but it didn't help resolve the problem. I'm using a Radeon ATI HD 4850 graphic card. Please help.
