Cut computer on and nothing seems to happen

I have Soyo motherboard.  When I cut the computer on from the power supply switch I note that the lights blink on the keyboard but the light in the optical mouse does not  cut on.  The cooling fan appears to not be on but the fan for the processor is running but nothing else seems to happen.  The lights blink on the CD drives and the hard drive light comes on. After that point nothing seems to be happening.  I am wondering if the power supply is not fully functioning or am I on the wrong track.  Software XP Pro.  I have tried to get it to boot to a cd drive with my xp pro disk, but this does not happen.

If you could describe what happened between the last time it worked and now, it would be helpful.  Otherwise, I can only point you to some things that can prevent bootup:

- motherboard shorting on case
- CMOS jumper set to CLEAR, instead of NORMAL position
- bad connections
- faulty or inadequate power supply
- bad RAM
- faulty video card
- bad cpu
- bad motherboard

If you suspect the power supply, swap another one in.  It is possible for power supplies to give indications that it works, but is unable to produce enough current to boot a system.

When you tried to boot up by cd did you make sure to change to order of boot devices in BIOS?  Or does the CD drive just not work.

Do you have any idea what caused all of this?

I have replaced the power supply and that is not the problem. I have been reviewing the motherboard specs and it supposed to only support AMD Athlon processors but I have had a p4 in it.  I have been having some strange problems. I have only been rrunning it since April 03. It will not boot and it does not allow me to go into setup.  I cleared CMOS and still nothing happened.

You haven't described what changes you did between the time it worked and the time it stopped working. unless you're saying you didn't do anything and it just happened.  I am also suspicious of the claim that the motherboard supports both AMD Athlon and Intel P4 processors - their chipsets are incompatible with each other.  What manufacturer and model motherboard do you have exactly?

Actually they claimed to only support AMD Athlon but I had installed a Intel P4 and it has been working. It is Soyo P4S Dragon Ultra, with a name like that I may have the info backwards but it does have P4 processor. I used it last night and it got flaky but came back to normal later, guess the election was too much for it.

I don't know who told you that, but the motherboard is a strict P4 motherboard: http://www.pcstats.com/articleview.cfm?articleID=1144

Did you try another video card and RAM that came from a working system?

It just quit working. It worked last time I used it and the next day it did not. I am trying to put on a new cooling fan I noticed the other had broken loose and cause the processor to be loose, but now I can not figure out how to connect the new fan since the old holder had part of it broken off.  I purchased a copperChill  P4 by mad dog, but naturally I am now having trouble finding the right part to get it connected to the motherboard.

A heat sink breaking off and the cpu being loose are serious problems.  You can buy "heat sink retaining clips" to replace the broken one.  Someone else asked about that part recently.

What broke was attached to the mother board and appears to be a very common device for attaching the cooling unit to the motherboard, however trying to buy another one is not that easy.  I have been to compusa, bestbuy, computer warehouse, and the commet I most often hear is that a lot of people have been in looking for one of those, but no one has them.  I ended up buy a new motherboard. I have installed it and for some reason it appears to cycle past the the CDRW and DVDRW and then stalls at the hard drive. This most difficult part about putting the new board it was the upfront lights and on/off switch. So I am not left with taking it to the place I bought the MB and see if they can fix it.  All this over a little piece of plastic that you can not seem to buy.
