Hi!
I'd really appreciate some help here. I have an old Asus P8H67 motherboard and i had to update the BIOS in order for it to find a newer processor. I updated the old BIOS (version 0803) to the latest 3801 BIOS and it caused my system to become very unstable. I was running an i5-2400 with the 0803 BIOS and the cpu usage used to be under 10% while just browsing with firefox. As soon as i flashed the BIOS to the latest version 3801 my cpu usage went up to 25-50%. After that I put in my slightly newer i5-3470 cpu and its cpu usage is also fluctuating between 25-50%.

...Anyway I'd like to know if i've destroyed my motherboard from flashing the latest BIOS on top of a very old BIOS without doing it in increments. Did I miss some some important BIOS in between that recognizes Ivy Bridge from Sandy bridge? If I did, is it possible to somehow backtrack the BIOS versions to older ones in order to get my system stable?

I'm scared to game on this because now the temperatures according to Speccy are 50-60C while just browsing.

My current specs:
Motherboard: Asus P8H67
BIOS: 3801 (flashed straight from 0803)
CPU: i5-3470 (updated from i5-2400)
RAM: 4gb 1333mhz ddr3 + 8gb 1600mhz ddr3
GPU: gtx 960 4gb
OS: windows 7 ultimate 64-bit

p.s. It's a pity I can't really do anything about my current situation since socket LGA1155 mobos are no longer available (if mine is broken for good). I know it's time to get a better pc for gaming but i'll have to wait for the prices to go down on ddr4 memory and get a mobo with which i can update the cpu in the future.

Your mismatched memory is a excellent way to cause poor performance.

Flashing BIOS returns BIOS settings to default settings. I suggest setting the memory according to the memory manufacturers recommendations. What that would be, I don't know.

Your choice of hardware and your choice of BIOS settings are probably the main cause of an unstable system. I suggest using a matched pair of DDR3-1600MHz memory.

A good quality thermal compound can help reduce temperatures.

Thank you for stating the obvious for me :) I completely forgot about having mismatched memory and didn't take the BIOS default settings into account. So I took out the 4gb of 1600mhz ram sticks and the cmos battery again and restarted the computer (i actually have 8gb of 1333mhz and 4gb of 1600mhz). Unfortunately it made no difference while running on only 8gb of 1333mhz ram:( The system is still unstable but thanks for pointing out that my ram speeds could be causing the problem.

These values were taken from Speccy and I have no idea what they mean except that slots #1 and #3 have identical 1333mhz ram and slots #2 and #4 have identical 1600mhz ram. Before the BIOS flash there was never a problem with them so... who knows what could be the problem? Is it a possibility that i should somehow "set the memory according to the memory manufacturers recommendations"?
