This computer took a fall on the floor! So with that
The light inside the motherboard is glowing yellow? I dont remember if it was yellow before or not, however at first I couldn't get it to do nothing when I turned it on from the front button, only the 2 fans started.

I took a look at things and found out the after removing the cooler the processor fell out on the table and wasn't in tact.

I raised the small lever put it back in place, lowered the lever tightly replaced everything and now the hard drive boots up, cd player runs but the monitor keeps saying cable unplugged? tried several different things with no luck.

So question is if anyone knows if that light inside on the motherboard is supposed to be glowing yellow all the time? or should it turn Green? as it does on my #4400

And if so would you replace the processor? or do you think the fall might have damaged the motherboard?
Thanks sorry about length but wanted to give as much information as possible,

If you don't get the normal single beep when powering up, the motherboard is not working. The light probably needs to be green.
It's very difficult to guess what the problem is. It could be the motherboard, power supply or something else. Don't eliminate the power supply just because you see some signs of power. It has to supply several different voltages and a single one missing can kill the system.

" processor fell out on the table and wasn't in tact". Do you mean the CPU was broken in two?

Not broken but where the pins push into the board it wasn't pushed in tight(prob from the fall it took) and (when I removed the alum cooler with fins)it just fell out of where it should have been locked in, I checked it out re-installed (says pent #4 on it) replaced the cooler but yellow light is still on when I powered up.

I was actually thinking my self about the power supply because the hard drive just doesn't see to be running as it used to, seems very quiet, and kinda like its running slow?

I have an extra power supply here I may try to swap them out and see if anything changes, My daughters computer and its not really used for anything demanding worked great before this...idk. Thanks for help all !!

Any and all suggestions are welcome and appreciated!

Oh and forgot there is NO beep when powering up, just a slow like coming to life action
thanks!

NO beep means no post test.
The Post checks the memory so I'd certainly reseat that.
The Video card, if installed, could also be a problem. A video card pops out of it's slot very easily and it's not very easy to reinstall it squarely and fully into the slot. I use my handy dandy LED flashlight to make sure the vid card is completely seated and evenly spaced from the slot. They can really be a bitch!

"NO beep means no post test"

That's correct. But no beep(s) means that the motherboard is not working and the POST is not even able to run. If the POST test fails, you will get error beeps.

Oks Im going to go try all of the above,
I'll post my findings when done,
Thanks all!!
