My secondary computer, a Dell Dimension 5100, 2.8ghz, 160 G HD, 4G ram, 305 watt power supply, mfg 2005, win 7 OS, has a black screen at startup. Monitor good, has monitor logo at initial power up when power strip turned on, not computer, then goes to standby mode, and then black. I tried a second monitor also, still dark. I replaced video card, and tried onboard video, still no good. Fans run, hard drive spinning, power light lit on mother board, CD and DVD drives spin up. I have 4 sicks of 1G ram, which I removed one at a time, still no joy. I removed battery to reset BIOS, still nothing. I tried the F8 key, with no effect. The power light on the front of the computer stays amber. I tried control-alt-delete also.
Where should I go from here. Could it be a virus? How can I trouble shoot this?
