Hi everyone
sry for my english not a native speaker
So 3 days ago i still used An phenom x2 555be unlocked to b55 3.5ghz stable on a msi 770-c45 mobo,i sold the mobo and cpu together and now the buyer cant open the cores no matter what he does.. He says that his monitor turns dark and that his pc isnt shutting down and does nothing(just the leds are on).. He uses the same moboand same cpu why would he have any problem unlocking it when i had zero problems? i checked his setting and they are set as right,any ideas?

pictures of mobo settings
