Weird bios issue!

[Fenixriot]

I have an i7 2600k, a Gigabyte z77 ud3h motherboard and 16gb ddr3 memory. 

Every once in a while my computer will not get past bios splash screen, however what is strange is that the bios screen is the old bios and not the updated version which is what is installed. 

The only way i can get it to post again is by resetting cmos, as no amount of rebooting computer gets it past that screen.

 

Just wondered if anyone has come across this before and what could be wrong?

 

Thanks.

Maybe theres something not right in the new bios settings and it trys to recover by your old bios, i think you have to dig into the manual for that.

I thought it could be that, but downgraded bios, still the same issue, and then upgraded again, and still the same.

I would say 8 out of 10 times it boots fine, but the others it either freezes and cant move mouse or use keyboard or it reverts to the old bios flash screen and cant do anything on that either.

Im just hoping it isnt something faulty as cant really afford to buy new parts.

I have tried several of the older ones with no luck.

No, I mean the other BIOs config... your board has dual bios chip.

Hmm, that is puzzling... have you reset CMOS so that there should be no OC or other issues interfering with the troubleshooting?

If you have already done that, then all I can think of is switching to the other bios, then flashing that with the latest bios.
