Its hard to read, but is that the Windows 7 recovery screen?  You might want to try and patch the OS with the boot/installation disk.  Could be an underlying hardware issue, but a repair install might get it running if the OS has self-bricked through an OS.<div><br></div><div>EDIT: I'm basically in agreement with Alan.  If its the HDD, it zapped the OS sector, so hence my reason for repair install.  If that works, consider a new hard drive.  </div>

I have Vista 64 bit. Home Premium.
