This error code indicates registry problems.
However, if you can't boot your machine and download a registry scanner you will have to create a boot disk and change your bios setting to boot from cd.
Using another PC you should create a boot disc. You can get a boot disc image here:
Copy this onto a CD and boot your machine from this disc, rather than the machine's hard drive. The CD has registry tools that should be able to fix your problem.
If you need further help please respond here and I will try to provide additional guidance.
