My friend's computer is a HP 7965 (p4 1.7ghz, 512ddram). And he seems to be having problems loading. He can enter his BIOS just fine, but he cannot enter Windows XP because it won't load. During the password, it freezes and an error message pops up saying "c_20127.nls file missing." This just happened after he used the recovery for hp program. Any help?
