There are loads of posts about this on enthusiast forums with most people RMAing their mobos. So basically, I'm only fine until the next reboot, because my mobo does not have a BIOS atm.
I hope ASUS CrashFree BIOS works fine or else I'll have to disassemble the whole system and go try to get some warranty.
So, \Fenix, don't try WinFlash at home xD
