I just built a computer a couple days ago and everything was working fine. I downloaded partition magic so I could partition the drive. I opened the program and it asked me if I wanted it to change some things so I hit ok, there were maybe 2 or 3 windows. After this was done partition magic closed itself but the computer was fine. After 5 minutes of browsing the internet the computer crashed. I turned off the computer and now when rebooting it gets to the windows animation screen but then reboots. I've tried booting from the Windows 7 install disc to reinstall windows but the computer only sees a 200MB drive that's inaccessible when I have a 1tb Samsung Spinpoint drive. I have tried using Dban but it just says there could be bad sectors and it closes. I've also tried connecting the drive to another computer to reformat, but the other computer only recognizes a 200MB inaccessible system drive. Any help would be appreciated, thanks.
