Can you get in to windows at all?

What brand is your hard drive? Seagate, Samsung??

The problem is i can't get into windows at all. The system restarts before it can show up with the desktop. So, its not possible to upload those minidump files. Also i dont know the hard disk brand. The thing is i never had a need to know that.

Then use the Windows 7 DVD and try to repair the installation.

Do you heart the drive spin up?

The only tool that I know that can fix disks is Spinrite:https://www.grc.com/sr/spinrite.htm

But that will cost you money.
