A friend of mine is having a problem with a malfunctioning temperature
gauge:

"The PC's temperature gauge is apparently FUBAR - it thinks it's
something like two hundred degrees inside my computer, but, cracking the
case open, it's actually rather chilly in there, and leaving it off
overnight hasn't decreased the ostensible "temperature" either. So every
time it starts up, the fail safe measures kick in and it automatically
shuts down within three seconds."

Is there any way to fix this at home (without requiring specialized
skills or tools), rather than having to send the machine back to the
manufacturer for repair? For example, is the gauge a recognizable
discrete component that could be simply unplugged pending purchase of a
replacement?

Thanks,
