Computer won't boot - no beep, no light, blank monitor

by Elrood - 2/3/09 2:21 AM

Here are the symptoms when I boot up:

The blue light on the front of the tower wont turn on (it always used to).
There is no beep or beeps at start-up.
Everything seems to come to power. The CPU, the fans, the hard drive, etc
The hard drive, a few seconds after booting, gives one audible click, as if something inside was moving into place, but then everything sounds fine. I dont know if that click has always been there or not.
The monitor stays off (the power light is orange) and is black.
With the power cord plugged in, the green LED power light on the motherboard is lit.

Here is the backstory:

It all started when I went to boot my computer after adding RAM. After t he motherboard splash screen, it went to the black screen that said Disk Boot Error
I unplugged cables and re-sat the RAM, and then everything worked fine.
Over the next couple weeks I got the Disk Boot Error a couple more times, each time fixed like the last time.
When I awoke his morning, my computer had obviously restarted itself because it was on the Disk Boot Error screen. This time, nothing I have done has fixed it.
Now, my computer wont get that far. I get nothing on the monitor. The monitor doesnt even power up.

Here are some possible causes:

The very night my problems started, I added 2gb of RAM (two 1gb strips) that are compatible with my motherboard.
Today, when looking around inside my computer with it turned on, I noticed that the 2 fans over the hard drive had failed. One was not spinning at all, and the other was spinning quite slowly.
So I have two possible explanations: adding the RAM which directly led to my having these problems, or the fans breaking on the hard drive, and the hard drive overheated and crashed. Both are possible but totally unrelated.

Here is what I have tried:

Clearing the CMOS on the motherboard.
Reseating the RAM, plus trying it with only the old sticks or the new sticks.
Unplugging virtually everything and reseating everything.
Fearing a hard drive crash, I tried the freezer technique to get it to boot to at least backup some files.
Even though the problem seems like it could be the monitor or he video card, I dont think so. The errors leading up to his had nothing to do with the monitor or video card.

Thank you much for your help!
