PC Hangs for no particular reason

[Tyrone Clark]

I'm running Windows XP Professional

My computer keeps hanging, there is no particular program
which makes it do it, it just stop, the cursor doesn't
move, and Ctrl Alt Del doesn't work. The only way I can
make it work is to press the reset button on the box. Is
there any way i can find out why this is happening, and
how to stop it?

I also recently did all the XP update (Critical and the
normal ones). i have a fairly large knowledge on how a
computer works, and am quite advanced with computer use.

Thanks for any help anyone can give me

Check your error logs there might be something there
pointing to what is making your machine lock up..

most probable is ram related but dont go with my word on
that since i have seen many other cases in whichh it
happened.
