If you had this hangs/freeze with this component call, have this sollution:

-

Boot your PC.

Pressing F8 repeatedly.

You see Darwin prompt, now type -S (Enter)

Now, you see something lines, bla bla bla and a prompt.

Now, type:

/sbin/mount -uw / (Enter)

rm -rf /System/Library/Extensions/AppleSMC.kext (Enter)

rm -rf /System/Library/Extensions.mkext (Enter)

rm -rf /System/Library/Caches/* (Enter)

reboot (Enter)

Pressing F8 repeatedly. (Again)

In Darwin prompt, type -v (Enter) (this for verbose mode)

See it boot fine without errors.

Goodluck,
