Hi All,

Built pc with Athlon II X3 435 and Windows 7 and it's been working fine for the last few weeks.

I attempted to unlock the 4th core (using ACC / Unleashing mode in the Asus Mobo Bios) and when I saved changes and attempted to reboot, got a BSOD that flashed quickly and then reboot.

So i figure the 4th core isnt unlockable but now when I went back in and turned ACC off, when I try to boot on the 3 cores, Win7 won't start.

It gives me the option to start normally or start in repair mode. Neither one gets anywhere. They just hang forever.

Any ideas?
