Re: GZ-Z77X-UD5H Random freezing and shutdowns.
I tried a different OS to see if this happened, and it did not. Of course you can't install Intel USb drivers int he other OS since XP wont accept them, so perhaps that is it. I have 4 CPUs, 2500K, 2600K, and two other Ivy CPUs, 3570K and 3770K. This issue only happens with the 2500K at stock, and is isolated to it, if that makes any sense.
At some point I think it is CPU dependent too, as these issues aren't easily reproducible.
FYI if you are freezing in the BIOS, you need to RMA your board, at least if you are at stock. If you are OCed and freezing in BIOS your OC is unstable, notice your BIOS temp isn't your idle CPU temp, that UEFI puts a load on your CPU.
