Please Help Unknown Freezing Problem

[computernoob]

hi, for the past 9 months my computer has been freezing randomly.
It freezes while i use it and even in screen saver mode. All i can do is hit the power button. Im getting irritated and am trying to figure out the problem. I am pretty sure it doesnt have to do with overheating because my fans are working properly like they have been and sometimes it freezes after 2 mins of turning on... I have run deep scans using Norton Anti Virus and also scanned using SpyBot and Adware SE Personal and i have not found a issue that could be causing this. Any suggestions?

My Computer: Windows Xp Professional
Version 2002



Thanks!

I don't know if this will even do anything but sometimes the fans will be working fine but the dust inside makes them ineffective. Try blowing it out will and air compressor or a shop-vac. I don't know if this will help but just an idea.

When your PC freezes , after re boot go to>my computer>manage>event viewer and see what error has occured and post the error.
