My computer was working normally until it just turned off. Now, when I
press
the power button, the computer will turn on, but it won't start up. The
monitor is blank and on standby, like it is when it isn't getting anything
from the computer.

The light on the motherboard is on. All of the fans are working, including
the one on the video card. Nothing that is attached by USB gets power,
except
for a brief flash right when I turn it on. My keyboard, which is PS/2,
doesn't turn on either.

I did try changing the RAM, but that didn't work. I also tried switching
the
monitor on a suggestion from someone else, but that didn't change anything
either.

My hardware that I can remember:
Motherboard: Asus P4C800-E Deluxe
CPU: Pentium IV 3.2 GHz
Video Card: Ati Radeon 9600 Pro

Thanks!

Do this...

1. After powering off the machine and removing the A/C cord from the wall
socket...

2. Disconnect the HDD from the system; ditto for any optical drive(s),
floppy drive, and any other storage devices, printer, etc.

3. Work with only the power supply connected, your RAM, your video card &
monitor, (you can leave your mouse/keyboard connected), but nothing else. No
other peripherals, OK?

4. Power on the machine.

What happens? Do you get any kind of screen display at all or just a black
screen?

If you do get a screen display can you access the BIOS and manipulate
through the settings there for a period of time? Any problems at this point?

And the CPU fan is going, right?

If you are able to access the BIOS, check the temperatures shown in the BIOS
display. Any problem here?

If still "dead in the water" it's most likely the processor or the
motherboard; usually the latter.

Conceivably it could be a defective PS even though you're apparently getting
power to the system.

The problem here is that the only way you can definitively tell what's
causing the problem is by substituting components, usually not a practical
thing for the average user.
