Ok, Heres the problem:

I go to shut down my computer or even restart, the computer gets to saving your settings, passes that, then gets to Windows is shutting down your computer, then my MOUSE leaves and my comp freezes.  I have to manually turn off my computer.  Even if i have a prgram shut down my computer (lets say I installed soemthign and it requires a shutdown) even that doesnt shut it down.  Then when i try to turn it on, the monitor seems to not see the computer, even tho i didnt touch anything except the power button.  I always have to fiddle with my vid card taking it out putting it back in.  SOMETIMES it takes half a second for it to work (i do turn off the comp and take out the card then i turn on the comp and see if it works) sometimes it takes an hour. Honestly.  Then i get it to work and my mouse wont work unless i unplug the USP and replug it in.  (MX1000 - NEVER had this problem before in my life).  My Specs are as follows:

Windows XP PRO SP2
AMD Athlon 2600+ 2.1gHz
ATI Radeon 9200SE
DVD Drive - CD R/W Drive
160GB HD, 80GB HD
--BTW It is not overheating I have felt the processor when i turn off the comp

P.S.  I reinstalled Windows and even the CD wouldnt restart my computer it would go from 15-0s for the shutdown and then sit there.  I would have to manually turn it off.

Please Help.
Can you do this CLEANUP routine first of all and then see if there are any loose connections inside the cabinet?Sounds like the video card may be failing or the connections in the AGP socket are bad.

However if one of your CD drives has a faulty chip it can cause the computer to display the symptoms you speak about, so try disconnecting the power from all CD and floppy drives.have you tried a reset in the Bios or removed or replaced the battery and reset it that way.
Also did you reinstall the motherboard drivers after you installed windows.
it does sound like a component failing and hanging the computer, disconnect everything except the hard drive, floppy and the Graphics card, reseat the Ram mabye if you have two strips remove one , then try it, if it works add the dvd,  a process of elimination. add and remove until either it shows the problem culprit or works.  
have you got any old graphics cards you could swap with.
we have all been there
have patience instead of frustration,
