Just had a Windows XP Home system restore because of corruption. Ever since I
got it home it keeps freezing. It freezes at least once an hour during any
operation, ie. internet, outlook email, documents, etc... It completely
freezes, no mouse, no keyboard, no ctrl+alt+del.....nothing! I have to shut
down the whole computer and then restart it manually......upon start-up each
time there is no scan disk.

What could be the problem?!?!?

Thanks for any help!!!
