I have unpluged all extra boards and drives, etc. I also have verifyed correct voltages coming out of the power supply. The power supply fan and cpu fan run but that's about all it does. No boot screen, no bios screen etc. When I opened the case the cpu fan was unplugged!

hard drive is missing from the system. Or, just does not recognize it.
obvious - Remove any USB devices like drives and any media from disc player.
Its trying to load, but can't find bootable hard drive, CD, or USB...
the hard drive and re-seat (reconnect). Check BIOS by pressing an F key
during boot. Look on the screen for correct Function key. Might be F2 key.
Verify BIOS recognizes the drive. It must be listed! There is no going
forward if it's not. Check boot order and make internal hard drive first.
Save and restart.
You might not have your voltage set properly in your bios and/or your power supply is either insufficient or going bad on you. Have someone test all the leads and be sure the voltage produced is as it should be. Also evaluate your system as a whole and compare the wattage -vs- the power supply you have. (i.e. running a powered vid card.. tv tuner.. two hard drives.. extra ram AND a beefy cpu on a 150watt supply is highly unlikely.)
If its forcing a shutdown of the entire machine, I think it may be protecting itself from a voltage issue. What do you have plugged into your USB ports? It sounds like it has detected a voltage problem coming from one of the devices connected to one of its USB ports or something near it and to ensure that the motherboard doesn't get fried its shutting the computer down.
The message is telling you that its detected a device that is over the allowable amount of electrical current and is protecting itself from electrical failure. It could be a problem with the USB jumpers on the motherboard that connect the front usb ports. You might try unplugging these connectors and try to boot up the machine. Leave them unplugged and boot up the machine, if you still get the error after that, it may be a grounding issue with the motherboard mounts that anchor the motherboard to your computer case. If you have any extra mounts underneath the board that you aren't actually using but are coming in contact with the board, you may have to remove them, which would probably involve removing the motherboard from the case.
install the flat cables coming from the hard disk drive, optical
units and floppy disk drive. If you didn't install these devices to the
case yet now it is a good time to do so.
The cable from the hard disk drive must be installed on the IDE1
(primary) port and the cable from the optical unit must be installed on
the IDE2 (secondary) port. The floppy cable should be installed on the
floppy port. To install the cable, just pay attention on the red wire,
it should be installed facing the "pin 1" marking on the motherboard.
This marking is usually a number "1" or "2" painted on one of the sides
of the connector (the opposite side should be marked "40" or "39", or
"33" or "34" in the case of the floppy port).

The next step is connecting the power supply. The power supply has
one 20-pin connector and your motherboard can have an extra 4-pin
connector called ATX12V, which should also be installed (not all
motherboards have this extra connector). You may need to lift the
motherboard in a 45º angle with the table you are using to assemble your
PC, since usually the wires from the power supply aren't long enough to
reach the motherboard while it is on the table outside the case.

You either have a dead CPU or a dead motherboard or a partially-dead power-supply -- the power-supply should supply different voltages to different computers, i.e., one voltage to spin fans, and a different voltage to power the RAM, and a different voltage to power the motherboard. So, it can be "partially" dead.
Borrow a power-supply, and try that first.
If all else fails, take the computer to a qualified technician.
First off, please use proper case. All upper case makes it look like you are shouting. Thanks.
Try removing everything you can possibly remove from the outside other than the monitor. Remove any cards inside not needed to boot (sound, NIC, modem, etc.).
Disconnect mouse and keyboard, too if it will boot without a keyboard. Some systems will halt at the BIOS screen without a keyboard.
When you have a minimum config for booting, boot and see if it stays on. If so, one of the items disconnected is the culprit.
If not, reconnect keyboard (if disconnected) and boot into Safe mode by tapping F8 after BIOS screen. See if it will stay on in safe mode. If it will stay on in safe mode, problem is O/S.
If it won't stay on in safe mode, see how long it will stay on at the BIOS screen. If it will stay on indefinitely, you could have flaky RAM or possibly hard drive. Power off, unplug power cable, remove hard drive and see if you can boot to the Windows CD. If it will boot up to Starting Windows and stay on, probably not RAM although that is not a definitive test. At that point, I'd try another hard drive and see if the O/S will install or try wiping and reloading the original hard drive.
Hi infofreak, Try to follow these steps one by one. 1. Remove the power supply cable from the hard disk, CD/DVD, floppy drive or any other device you might have. 2. Check the wires that go to your front panel ;pwr sw, reset, hdd led, pwr led, speaker etc. Make sure there are at the correct position. 3. Now turn on your computer, if ok you should see some info on your monitor screen. 4. If ok, you can put back the power cable to hard disk only left the others open. Turn on the computer , if ok then proceed with other device one by one. If something wrong in between then maybe your power supply isn't deliver enough power to your system. Get a larger rating power supply. 5. If step 3 is not ok, then take out the power cable on the motherboard from the power supply. Wait a few seconf and place it back to the connector. Make sure it is securely fit, you should hear a click sound once it is fitted in. Turn on your computer. If Ok repeat step 4. 6. If still not ok, as step 5 this time take out the CPU.
Try the above steps and see whether they can solve your problem. Good Luck
