Often a sign of a failed hardware item. Could be HDD, RAM, other. Tell more how you accessed C if it won't start?
Asus laptop crashed. Will not start in safe mode. Will not start with recovery/restore discs and laptop version. When doing restore it say completed but still will not open. My hard drive changed to x drive and will not change back nor identify the c drive, however I can access the c directory list but only the list. Please help!
