Do you hear anything during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better. It is starting to sound like 1 of 3 things, Power supply, Video card or motherboard.
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #2: If you get sounds and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, Try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat try that.
Also take the time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The caps will need replacing to fix (not a job for an amatuer). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.

If your dell machine is recognizing the keyboard properly and installing its own built in drivers properly then the USB ports are working and it a problem with your keyboard

If you look closely at the motherboard the pinouts are there. I have always had to play with the reset and power pins and by this I mean that if they don't work right then turn them around. I have also had to put the cable marked reset on the pins marked power. The others are marked (hdd led). I have found this to be true with all dell machines.

OK the first step is to remove the side of the case and check that all the leads are firmly inplace. - If this does not fix it post a comment.
