Those CPU core temps are high, you should check the CPU cooler and replace the thermal paste.
You can post those pictures the same way you posted the CPUz shots.
The last picture is where you change the VCCIO voltage. Attachment 187032
What did you set your CPU offset voltage to?
From you motherboard manual, Asus P8P67 Pro Attachment 187033
Your current RAM voltage is 1.662v on Auto, this is too high a voltage.
Your CPUZ SPD tab says all JEDEC and XMP voltages should be 1.50v.
Let's lower the DRAM voltage, on the EFI page above change the 'DRAM Voltage' to 'Manual' and set it at 1.550v.
The voltage is due to your 16GB RAM, with 4GB RAM I would recommend 1.50v.
Then change the VCCIO voltage to 'Manual' and set it at 1.120v.
Then check you system for stability, keep a constant watch on the CPU core temps, don't let it go over 75°C.
Let us know if there are any stability issues.
We don't see many issues with Avast, most BSoD analysts here recommend it, I use it myself.
Anything is possible, though.
Lets look at the CPU temps and the RAM settings before you look at software, for now.
