the lights are probably fine. Just check connections.

I'm guessing you've got some problem between your monitor and your video card. Is the connector going to the video card or the motherboard? Also, if you can change the monitor cord, and see if thats the problem. Dust could get in the connectors and cause a problem, or just the cord could be dying.

Was the problem that prompted you to work on it that it wouldn't post ?

Was it working & refused to start when it was turned on ?
Do you know if it has a video card or onboard video ?

A couple of things to try,

Make sure it is off & unplug it.
Press the power button after it's unplugged to desipate any stored electricity.
Open the case
Remove the memory sticks & reinstall them
If it has a add-in video card make sure it is seated in the slot properly.

Try it.

If you still get no display try this,
Make sure it is off & unplug it.
Press the power button after it's unplugged to desipate any stored electricity.
Open the case
Look around the motherboard battery for a jumper to clear the CMOS
Move the jumper to clear the CMOS
Wait a minute & put it back in it's original posistion
If you can't find a jumper remove the battery for a minute then put it back on.
Try it.

What make/model is the computer ?

How did the problem start ?

What color is the CD light usually ?
You mention it being red, is it normally red when you use it ?

From what you are describing there is a strong possibility that you have 1 orf 3 problems or a combination of 2 .

1. The power supply has failed.
2. The CPU has failed.
3. The motherboard has failed.

Unfortunatly there is no way to troubleshoot the problem unless you have known good spare parts.

It is possible for the onboard video to fail but the only way you can eliminate that possibility is to install a video card & try it.

I would take the motherboard out of the case. Place it on a cardboard box, away from other metal objects. Put only the processor and the heatsink fan on it (don't forget thermal paste), and one stick of ram. Now, make all your connections from the power supply (4-pin cpu, 20/24 pin motherboard) You don't need a cd drive or a hard drive connected for the computer to at least power up and display an image on the screen.

Now to start the computer without the button on the case, you'll need to take a screwdriver and touch the two pins for the power connection from the case would plug into. Touch both with the screwdriver at the same time. If this isn't a custom built computer, it may have a unique type of power connection. See if you can position the case so you can get the cables to reach the motherboard, then use the button like you normally would.

Let us know how it goes!
