Home Edition SP2) has been giving me some problems for quite a while now
with regards to the above referenced error. It will simply not POST at all.
The cryptic error evidently references some kind of temperature monitoring
of the Intel processor.
All the information I have gathered so far indicate anything from faulty USB
cards to a failing motherboard to a bad RAM chip. I have no idea what is
causing the problem, which seems to be very common with these units. But I
do know what makes it boot again.
I unplug the tower and rip off the side panel. Depress the power switch for
about five seconds to bleed off any latent power in the system, pop out the
battery and wait a few minutes. Pop the battery back in, button up the
tower and plug in the power cord, keyboard and mouse and monitor. Power up
the system and it boots. It has done this three times in the last seven or
eight months and this routine has fixed it every time.
You have to get into the BIOS and tell it to disable the onboard audio,
forget about any floppy drives, and set the clock. It forgets all this
information, apparently, when you leave the battery out for a few minutes.
I hope this information will be of some assistance to someone who is having
this issue. It took me about a week to find all the information the first
time this happened.

Disconnect PC from mains
Press/hold power button for ~15 sec
Open case and remove battery
Press/hold power button again
Reinstall battery (right side up!)
Close case
Reboot.

Always include the system model in your posts. :(
New mobo and Pentium? Or just a new combination? Are you sure the combination is compatible? Did this combo ever work, or DOA out of their boxes?
Only "sure" fix I know for that BIOS error message (assuming not a hardware failure) is forced reset of BIOS which is what you did by pulling the battery and holding the power button on the tower.

I ran across a similar situation with a Dell 8400 --- unplugging, discharging, removing the battery, discharging again even reseated all the cards and memory sticks, etc and all with no success. It was after reseating the processor, the machine got past post, and Windows began booting, and just when all seemed to be resolved it blue screened on me with a PAGE_FAULT_IN_NONPAGED_AREA with a STOP value of 0x00000050.
Now it's to determine if there is bad RAM (main memory, L2 cache, or video) or a MB that's gone bad.
