Bios opens with warning F1/F2 Hardware Monitor found error

December 26, 2011 at 07:45:46
Specs: Windows XP
Sony PCV J120 (really old machine I am trying to help a friend with)
Win XP Pro
On startup, Bios reports: "Hardware monitor found error." (F1 and the machine runs fine)
F2/Power/Hardware Monitor
All set to Ignore (Sony says MB Temperature should be set to display)
I set to display and temp, it shows 65,482 deg F (Yikes I have a thermonuclear device on my hands)
Under Power Fan Speed it show red N/A (I can't modify this setting as it scrolls past as I scroll down the menu)
I noticed that when removing the power supply to clean the cpu fan the PWR Fan connector had come undone but reconnecting it didn't help.
I removed and replaced the CMOS battery.
When I set to display, CPU fan speed also shows odd 5400 RPM

Does it finally boot up and work?

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Yes. F1 goes to normal Windows screen and machine runs fine. Now, if I could somehow get it to skip this step, I could return this machine to the owner and get this off my mind since it doesn't seem to affect functionality. I assume the 65000 deg. F Motherboard reading is false!

OK found in BIOS "Halt On" and set it to "No Errors" and now it shows a dos screen for a second then goes straight to Windows without having to choose F1 or F2. Of course, I still have the option to interrupt using F2 if I want.
I can't mark this as best answer so please do if you can. I don't see how to mark as SOLVED either.

That 'solved' rating is just an ego thing. Don't worry about it.

Sometimes the bios may show a hardware error if there's a conflict involving one of the cards. The solution is often as easy as putting the card in a different slot.

Also, check the voltage on the cmos battery.

CMOS battery tested at 3.10
The error seemed related to a Power Fan that read N/A in red.
I will try and see if any of the cards are at fault.
There is only one modem card and another ethernet adapter to switch around.
I opened and changed out the power supply fan as well as the cpu fan and checked the PWR Fan connector on the MB but none of these changed the warning OR that pesky MB temperature reading of 220deg C or 65000deg F.
I do prefer to know the answer more than a workaround.
Thanks for the suggestions.

Removed all cards and no effect.
I am happy that at least the workaround "solves" the problem of the warning screen.
