Vista x64 BSOD issue!

Hi all. Yesterday my new PC with Vista x64 had a BSOD. After the BSOD, Vista would not start back up, no matter what I tried. It wouldn't even startup in safe mode, safe mode with Networking, and I had no success when I tried a clean reinstall. I kept getting sent back to Windows Error Recovery screen or the repair screen. On a second try at a reinstall, I came to a new blue screen that said "Windows has discovered a problem and is shutting down to prevent any problems, etc. Page Default In Nonpaged Area". The only thing I could get to was the BIOS. Windows would not startup at all, in any mode.

Does this suggest the hard drive went dead? That's the only thing I can see. Videocard is working. Power supply is working. Motherboard is working. So is the soundcard. I ran memtest on the memory not long before this occured with no errors. Since Windows won't startup and I don't seem to be able to read anything off the hard drive, I assume this is a dead Seagate 7200.10. Some Indian guy at Microsoft said the hard drive was corrupt, but you guys probably don't trust some support guy reading from a manual anymore than I do.

Anyone have any ideas? Thanks!

Thanks badge! Tried your suggestions, and on the repair, it told me it was a hardware problem. So again, something is us with hardware. Don't really know where to start other than memory or hard drive. Funny thing is, my 64-bit Vista disc wouldn't get past the "Windows is loading files" screen. The progress bar at the bottom would go to the end and nothing would happen. But put in the 32-bit disc and it brought up the appropriate screen.
