it was showing that your c: is of fat file system and also you installed mcafee in c: isn't it,so problem is not hardware but some software thati is your mcafee the updates you are downloading is not in accordance with your present system configuration, better switch back to old mcafee 10 or may be use some other good programs like avast,kapersky e.t.c;

Goto CMOS setup by pressing DEL key (or check the key suits for your board) in Advaced CMOS setup search for System Bios Cacheable and disable it...and go to Video Bios Cacheable and disable it...and now check it up...
