Dead XP machine - checkpoint Ithr

Machine was less dead than now, but, here goes......

Initially machine (Dell with XP Pro) would freeze about 1/10 the way through the first progress bar; then restart, then display the screen to choose safe mode, then on selecting, start trying to load Windows, then freeze about 1/10th etc and over and over again. Somewhere in this sequence it BlueScreened, but there is no helpful information about what components might be the trouble; just the four hex codes.   For a few days before this total freeze it had been crashing intermittently, but would restart and run apps for a while, then crash.

I ascertained that the HDD was readable by connecting as an external drive with a USB cable.  It spun up OK, and I could read its contents.

Not knowing if the problem was HDD or MoBo related, I tried moving the HDD to another [HP] machine even thought I doubted that it would actually work just like the original.  Apparently big mistake.  It didn't work, of course, and now with the HDD back in the original machine, on PowerUp I get immediately the following:

"Alert!
Previous attempts at booting this system have failed at checkpoint [Ithr].  For help with this problem please note this checkpoint and contact Dell Technical Support."

I'm not sure if this is just another manifestation of the original problem or the result of putting the HDD from the Dell machine in an HP.

Any information out there?  Suggestions?

The machine is long out of warranty, so I'm not expecting too much help from Dell.

Oh yes, the current HDD is a 500 GB, cloned from the original smaller one, but it has been working fine since it was installed months ago.

iThr are part of the thermal probes for the CPU on the Mobo. Is the fan working correctly? You may have fried the CPU. Test the fan and if need be, the CPU to make sure they are operational. Also, take some canned air, blow out the vents, the heat cage, heat conductor, etc.
