Computer keeps crashing

Microsoft Windows xp home edition w/sp2

Specs: Windows XP, 1024 MB
The problem is very frustrating: my computer keeps freezing. In other words, the mouse pointer is unable to move, I cannot use the keyboard, and therefore cannot use Ctl+ALt+Del to shut down processes. In order to fix the issue, I need to turn off the computer at the mains and sometimes I notice that the loadingup of windows is slow.

At first I initially thought that the issue was spyware related and so to that effect, I reinstalled windows. No joy, the problem occurs even after a fresh installation of windows. There is NO pattern or warning signs associated with this particular problem, it really is random indeed and I must note that the length of time that it takes for my machine to freeze seems equally variable.

Ok guys some observations:

I was watching youtube and the computer froze (exactly the "same" as it has been). The music I was listening to on youtube died, as if it had been paused along with the mouse cursor not being able to move, or me being able to type. HOWEVER, the curious thing is that I use an infra red mouse and so if it is not connected or if there is no power, then the red light does not appear. The red light was still on even after the computer had frozen.

I checked my Device Manager, and all hardware periphals, no errors, yellow exclamation marks or warning flags.

I ran CHKDSK from the command prompt in the Windows enviroment, and it reported no errors or problems there either.

I wasn't sure as to what info was needed from my BIOS so I wrote it all down:

I notice that whenever I browse the internet with firefox, firefox keeps crashing: this seems to have no impact on when my computer freezes however.
I have checked eventviewer, and I notice that there is a significant number of yellow exclamation marks all stating the same thing:

Event 51

"CPU Temp: 90 C

Your motherboard temp is high & your CPU is overheating.

Unplug the power cord, open the case, blow out all the dust. Make sure all the heatsinks are dust free & all fans are working properly. You *may* have to remove the heatsink from the CPU, clean off all the old thermal compound & apply a fresh layer of paste. Assuming you have a single core CPU, here are the instructions:

Your CPU is overheating! 90C is almost 200F...does that seem reasonable to you? The temp (at idle) should be in the 40's C.
