This isn't a commonly recognized BSOD error code (here's a table of all that I know: BSOD Index )

Can you get into Safe Mode? If so, first backup your stuff.
Since you can't do a repair install in Safe Mode, you'll have to wipe the system and reinstall Windows.

You may also want to try these free diagnostics:
I suggest starting all troubleshooting with the following diagnostic tests. They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:
H/W Diagnostics:
Please start by running these bootable hardware diagnostics:
Memory Diagnostics (read the details at the link)
HD Diagnostic (read the details at the link) - Test ALL of the hard drives.

Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Free Online AntiMalware Resources (read the details at the link). There are links to bootable antivirus disks on this page also.
