Question about Northgate PC Desktops
With no more information that what you have provided I would start by reseating the memory and video card if you're not using onboard video. Then I would check the hard drive via chkdsk, run it from a command prompt. If the drive seems ok the next thing I would do is reinstall the OS. If it still gives you trouble after that you have a faulty component (memory, processor, power supply, video card, or mother board) and I would start swapping in known good components.

For those who have this problem:
I just had the SAME problem. In fact, prior to my power outage last night, my comp was shutting down after sleep mode on its own.
It is your POWER SOURCE UNIT. I am not a computer guy, and, until today, had never opened up a computer before. After several posts like this hinted at the power source as the culprit, I took the shell off my computer and figured out what the power source was. (it's the little box in the back of your computer that sends power to the different parts. it has a spot where you plug your power cord into. there is also a fan on it.)
I monkeyed around and figured out how to disconnect it from all of the different spots. I went to Best Buy and bought their cheapest one (which has more voltage than the one my computer came with) and took it home. A little elbow grease and the new one was in. My computer turned back on right away.
Hope this helps!

You have power to the computer, but not
Bad Power Supply, with weak voltage power rail.
1) ALL the lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.
3) A typical Processor uses 51 to 125 Watts.
Depends on what Processor it is.
[If the computer in question is an HP Pavilion A645c, it uses an AMD Athlon 3200+ processor, that fits in a Socket A processor socket. (Socket A is also referred to as Socket 462)
The AMD Athlon 3200+ processor can use up to 76.8 Watts.
(2.2GHz, and a 400MHz FSB)
With a bad power supply, you don't have enough power to turn the Processor on.
(Computer dirty inside, as well as the Power Supply, is the leading cause of computer, and also Power Supply failure)
Suggestion is to test the Power Supply, or replace Power Supply with a Known to be good, compatible unit, for a test.
(Compatible being that the power supply,
1) Is the correct shape, and size.
2) Has the same amount of Wattage, or more.
3) Has the correct amount of power cables, and the correct kind )
Testing can be done with an inexpensive multimeter, or an inexpensive power supply tester.
One example of an inexpensive power supply tester,
