I'm certain that my CPU (P4 3.06gHz) is running far too hot and is the

of my unstable PC. The manufacturer claims the temp is normal for this
type
of system -

So its OEM?

If it is, take it back! Demand a replacement if its locking up. You paid a
price premium for support, so you might as well use it.
