With the old HD installed, when I power up the PC, immediately (no Dell Logo appears) it goes to a black screen with a flashing cursor at the top left. No keystrokes can be made. I just bought a new HD thinking it was my HD that crapped out...Still the same symptoms with the new HD installed. I can't even run the BIOS. A guy from work told me to remove the battery from the mother board to reset the logic on the mother board and put it back after about 3 minutes. So I did so. Now when I press the power on, the monitor won't come on (stays in standby) and the fans run really fast. Cleaned all the dust out of the tower actually. :lol: Also before all this started, as I stated before, when the old HD was in the system before all this started to happen I would get a blue screen sporadically. Before the total blackness, it got to the point where every time I would start up, I'd have about 3 minutes before the blue screen of death...I'm hoping its the mother board, because I just ordered a replacement. Thanks for your help.
