No problem Jayson. Everything I'm writing is just that - input. I'm no computer technician. But computer problems are the worst and I hate to go through them, so I know your pain. When problems arise, it makes you realize how much we rely on our electronics.

Disks and fans can spin up simply because they have power. Depending on the Mobo some will regulate the fan speeds even before POST based simply on some analog control circuitry. Once the advanced thermal management takes over (BIOS) then it's under fine control.
The beep is really, really important...
Have you tried a different video card? Does it have a video card or is it on-board video?
We bought a bunch of those small form factor Dells about 4 years ago and they're all beginning to drop like flies. Those small cases just don't allow enough airflow to cool adequately. We've gone back to mini-towers.

Regarding the power supply, I did try to check and clean the pins. Then I purchased another power supply for the thing and that didn't work either.
I believe the video card is on board on this one. I don't see any place where there is a detachable card unless I am missing something. I didn't think of the airflow problem until I actually had it in hand and was thinking the same thing. Seemed to get hot very quickly when using it to most of it's potential.
Sounds like the motherboard to me. My mobo fried last month and had the same symptoms. REplaced that (and the processor too, while I was at it) and everything else works fine.
Problem is, you can generally only tell if your mobo is toast by ruleing out everything else....

Had a similar situation with my son's computer. For Christmas he received a new graphics card and power supply. The first time there was a problem all it took was unplugging the PSU connector to the motherboard. Worked fine, for a couple of days. Second time around, I popped out the pins from the connector and cleaned them with rubbing alcohol, as well as the pins on the MoBo. There was some resin flux residue left inside the female pins. Haven't had a problem since.
Worth a try anyways.
@JRW good point. If the voltage regulators don't get up to proper voltage the mobo won't beep. It's worth putting a Fluke on the pins if you've got one. Replacement power supplies are cheaper than a new computer.
If the vid card is on-board (on the motherboard), you might want to check with a local computer shop and see if they can lend you a cheapo PCI vid card. It'll have to be a low profile one for that machine, but it's one way to check if your I/O board (the section of the motherboard with the external connections) is shot. They do tend to die in those machines. They're not too pricey to replace, either. Do you know of any local computer stores you can trust?
