Could be.......

However, the most common cause of Window's PC "freezing up", by far and
away, is a software conflict....

Hardware conflicts usually result in the PC freezing very soon after start
or being unable to start at all!!

Check any recently installed software.

Pay particular attention to exactly WHAT was going on / you were doing,
when the "freeze" occurred.

On reboot, take a look in the Event Log for any additional clues.

...
I am, and have been for some time, running XP SP3. Have had no
trouble until now. It is on a M3A78_CM mobo with a AMD Phenom 9950
Quad cpu and 4GB DDR2.

I find that it freezes up after being on sometimes an hour, sometimes
longer, requiring re-powering up. I have tried the RAM one at a time,
and I have changed hard drives. Same result.

So I figure it is the CPU or MOBO.

Anyone have a thought on this?

Thanks
