Windows XP Pro Locks-up Solid

[Tilson]

Frequently (nearly every session) my Windows XP Pro locks-up my PC, The cursor freezes, CTRL-ALT-DEL produces no results (not even the Task Manager), and nothing short of a hardware reset will get it going again. It always locks-up on Media Player -- seldom completing a single CD track -- but will also freeze when I'm not using Media Player. Now my XP has taken on a new quirk. When I select "Start/Log Off" to shut down the machine, the Log Off window never comes up, and I have to shut off the power to get it to quit. If anyone else has had this problem, could you tell me how you fixed it?

if your sure that its not the cpu locking up from over temp, you might try a repaire install of xp and see if that helps.
you might post your system spects too

if you boot up in safe mode do you still have this problem? have you scanned for viruses and spyware that could be freezing your pc? if you dont have these tools download install them and run them in safe mode.

virus tools:
AVG
housecall.antivirus.com (use internet explorer, you will need safe mode with networking to run this otherwise run in normal boot up)

spyware tools:
adaware
spybot
microsoft antispyware

how long have you been experiencing this problem? what steps have you taken to resolve the issue?
