Help with BSOD REGISTRY_ERROR 0x51

[Sonicx00222]

When I start up my rig, nothing unusual happens up until I'm logged in and startup programs begin loading. After a few seconds, I get a blue screen with REGISTRY_ERROR and code 0x51, which is apparently a severe registry error usually having to do with hardware. I wasn't getting this error until this morning, when the computer started randomly acting up. I can boot to safe mode, where Windows Update doesn't respond when clicked on. I tried the solutions at the Microsoft website, but nothing worked. I unplugged my devices and plugged them back in one by one, yet I still got the error when nothing except a different keyboard from usual was plugged in.

I don't know how to use the minidumps, although I know they can be decoded. Any help would be immensely appreciated, thanks!

Hello... look at your Bios and determine if it has changed or reverted back to a default setting, your backup battery is dead?
