BIOS CPU temp problem

[brownin]

ASUS P557D

It used to be fine, now all of a sudden it thinks my CPU is at a constant 93C, even after first turning it on.

Any ideas?

is your CPU FAN spinning constantly at a high speed? Are you over clocking by any chance?

Nope stock everything. Stock Cooler, Stock settings.

I'm almost 100% sure its not the real temperature, surely it cant reach that after a cold boot in less then 20 seconds?

I've tried making the CPU fan as fast as possible and that doesnt seem to make a difference. I've had to physically ignore the CPU temperature reading in the bios now so my computer will stay booted up
