Meanwhile, yesterday picked up a new MoBoard...is not as impressive as some MoBoards around, but i'm sure it will serve me well for few years and please me enough by it specs for everyday life!
Swapped the board (same brand from H77 to Z77) and didn't even have to reinstall my Windows 7 x64, no Sysprep needed! I did only remove all the previous Asus softwares & drivers (some drivers manually), Intel Mei, Reseted the H77 Bios board to default settings, a bit of cleaning in registry aswell, and that's it!
At first start all went smooth and lots of drivers were there already from previous chipset .inf, Cleaned previous H77/C216 install in the Device Manager.
I Just had to reactivate my Windows 7 (3days activation) and update the Wei score after components installed, cool!
