CPU Temp soaring and can't enter BIOS

Hi Guys

Im running a GA-p55a-ud3p mobo with a i5-760 with a coolermaster hyper 101 heatsink. No overclocking (albeit second hand gear).

I noticed the temperatures were high on the CPU but thought little of it. However, now even in low end gaming the CPU (according to realTemp) hits 99 degrees C straight away. Naturally I have had a dust clean out, reseated the heatsink with some new thermal paste (with a pea as per TH's directions) and finally, I decided to check through the bios to see if someone has cranked some weird voltage or something somewhere.

I reboot, press tab to get out of splash screen, press DEL key, and after post it just sits there and doesnt proceed either to OS or BIOS. weird. it has on occasion even registered that the DEL key is pressed and "prepare to enter bios" message appears, yet once post is complete it never progresses to the BIOS. I have flashed the bios to the latest version, no difference.

As I type, It's currently idling at 0-4% CPU usage and 62 degrees C, but operating normally.

Any Ideas?

Thanks Dan.

I can;t help with the BIOs I'd say contact support and btw you should uninstall that easytune crap... I had it with my gigabyte board and I noticed my CPU started throttling and outta no where my comp would act funny and it would say max 250 degrees then min of 0 degrees and sit at 20-40 the whole time (I...

Have you cleared CMOS? And used multiple programs to check the temp like core-temp and hwmonitor?

Yep I cleared the CMOS to no avail several times after i flashed it.

Did find gigabyte "easytuner" which after i installed it had some clearly wrong voltage settings! For some reason coreV was 1.3v instead of 1.17v! after i set it back, the CPU temp is .. better.. but not perfect. it now idles at ~47degrees, and gets into the high 60s but I suppose thats an improvement..

doesn't explain why I cant get into BIOS though...

I agree, easy tune is crap, but as of now, its all i can do to fix CPU voltage is open easytune everytime i boot and manually set the CPU voltages back to default. I cant enter bios to set it correct once and for all and the easy tune settings are always changed after i boot.
Focus is now on the bios problem. tried smashing all the keys and getting keyboard errors, then selecting bios, that didnt work either. tried falshing bios's, tried cmos clear. This mobo has DualBios. Can that be used to factory reset the bios somehow?
