Serious Problem

[Evil_Maniac From Mars]

Every time I try to boot up the computer, the computer gets to the Windows screen (with the logo where the loading bar is moving across the screen), and the loading bar gets partway, stops, does a quick blue screen (too quick to see what it says) and restarts. On top of this, the partition file says that I have 47()()()() megabytes free, when it's a 500GB HD - and I have about 200GB of data on there, which leads me to believe that it's been wiped. There's also an 8MB partition that I don't recall creating. Neither of my scanners (AVG and Spybot) picked up anything, but that's still a possibility.

Windows will also not start in Safe Mode or Last Known Good Configuration.

EDIT: Sorry, there is no second partition, just 8MB of unpartitioned space.
