Need to recover files from a corrupt? hard drive

[hoofhearted4]

i have a friend, who has an old PC. his died on him the other day. he said it would freeze at the windows logo screen and he got a BSOD. he has stuff on there he needs however. so i told him Id take a look for him.

 

I tried hooking up his PC to my monitor via VGA, and my monitor wouldnt read his computer? just went into power saver mode. so I hooked his HDD up to an external kit and tried to boot to UBCD4Win, but that game ME a BSOD? so i tried to see if i could just view it normally but when i plug the HDD, Windows wants me to format the HDD in order to view it. which of course, would be counter productive.

 

so how can I get files off his HDD? any other software I can try? i just had UBCD4Win from my days in school.
