Ics mcp61 pm-hm bios

[apd]

this is an hp 8300f comp. that continually indicates processor fan failure, and then shuts down. later with no changes it will boot right through and operate continuously with no problem. is there an alternate bios which will work with this motherboard.

That's probably an oem board, so bios flashes can be tricky. Have you tried resetting the bios? You can also replace the board battery for a couple of dollars. It's called a button battery, lithium cr2032 for many boards.
