I have recently started getting a blue screen of death (BSOD) error very shortly after logging in to my Windows 7 laptop. It is fine if I am in safe mode, but crashes every time when I log in to normal windows mode. Based on the memory dump it is some kind of registry error. I have copied the output from windbg below. I don't recall installing anything recently and I haven't attached any new hardware.

Once I waited for about 8 hours between booting the laptop and logging in and it worked again until I restarted and logged in more quickly. I am not sure how to proceed and if there is anything I can do to fix the registry problem. Is there anything I can do?

REGISTRY_ERROR (51)
Something has gone badly wrong with the registry.  If a kernel debugger
is available, get a stack trace. It can also indicate that the registry got
an I/O error while trying to read one of its files, so it can be caused by
hardware problems or filesystem corruption.
It may occur due to a failure in a refresh operation, which is used only
in by the security system, and then only when resource limits are encountered.

    HvCheckHive if the hive is corrupt.

Reinstall windows, the chances someone is going to look at all that and say THIS IS THE PROBLEM is like .0000001%. And i doubt it's anything you recently installed, windows just got corrupted. But good luck regardless. –  Sickest Jan 23 at 7:59
    
Try a registry clean up program. Your Windows is corrupted any way, so it cannot become much worse. –  Mixxiphoid Jan 23 at 8:04
    
you are assuming he can actually get into windows and do this. which i doubt he can –  Sickest Jan 23 at 8:11
    
Thanks, guys. I can get into windows in safe mode and I ran a program called Little Registry cleaner which did not help. I am hoping there is some way to at least know what part of the registry is corrupted. All I get is that stack trace with some kind of hex offset. It would be nice if I could find out what the key is. Also, I just wonder if there is some useful registry repair operation that I can do. –  busyspin Jan 23 at 22:18
