If anyone could help me, I am about to pull my hair out 
. My dell laptop will load the dell screen but then go black. It had windows 7 on it. So I went under and selected diagnostic test under adipto? In which I am use to seeing a Bios screen labled Bios. The diagnostic ran but and passed everything except my hard drive. It recognizes and list on the Blue screen HDD Fixed and list a number. BUT under my diagnostic ut list the following code. 2000-0151 Vadlidation 62721 Msg : Hard Drive 0- #########, incorrect status =3E.
PLEASE PLEASE someone help me. Do I need a new hard drive or does this mean I have bad sectors?
Thank you in advance :(
