I have a P4 2.8 processor and yesterday it locked up. My wife tried to restart and nothing only a black screen no beeps nothing. I removed the processor and reinstalled it restarted ok run for app. 1 hr. and locked up again. How do I determine if its a processor problem or a mother board problem.

It could be an overheating problem.

Download Speed Fan.
Install it and then run it.
Post the temperatures at Idle and about the time it starts locking up.

When the computer locks up it will not restart until I remove and reinstall the processor everytime, do you still believe this could be a temperature problem.

Hmmm.....did you try leaving the computer for a while before reinstalling the processor?

It is possible that, by the time you reinstall it, it has cooled down.
However, it there might also be another cause.

I tried to remove and reinstall the processor last night when I got home and it freezes as soon as the logon screen comes on now. and when I reboot I get only a black screen.

You sure you did it correctly?

Do you have the Windows XP CD?

The processor will only go in one way. I can't even get the computer to boot to anything the monitor even goes to sleep. This started with the computer freezing and now it acts like I have no processor or the mother board could be bad. I get no beeps I can't boot to anything including a CD rom or even get to the BIOS.

That isn't good...

When you turn the computer on, what happens. Full Details.

Nothing the monitor goes to sleep, the CD and DVD drives light up the hard drives start spinning but nothing else. The power light stays on thats it.

Did you clean the CPU and re-apply Thermal Compound ? ?
This is important.

[cmikec1]

Yes I cleaned the processor and  blew off the board with dry air (caned) then reinstalled thermal compound between the heat sink/fan and processor.

Thanks for the help I replaced the Mother Board and I'm back up and running.
