Please do not post just to 'bump' your thread. Doing so can get you removed from the forums. Not what you were looking for I would guess. Just be patient. We are actual people and it can take a while for someone to get to your issue.
Additionally, if you can't get out of BIOS and are stuck in there (per original post) then you will need a DVD/USB with the installation software to resolve this. And, to be honest, that may not fix your issue. From what you have said, the software may not be the cause. It could well be the drive is going bad.
I would look at that first. If you don't feel comfortable doing so on your own, then I would take it to a local tech.
