Hi, I'm having problems with my Dell Dimenison 8400 Computer. It is about 4 years old and has always ran great. I upgraded to a larger C drive about 5 months ago and it worked until today.
When I go to turn it on, there is no input to the monitor. The keyboard keys don't light up and the only thing that happens is the fan starts going at a high rate of speed. It sounds like a jet engine about to take off. The power supply fan is turning. In the front, the harddrive indicator light remains off.
Does anyone have any ideas as to what the problem is before I start taking the thing apart? Should I replace the power supply? The C drive?
Thanks for any input.
