BSOD with BUGCODE_USB_DRIVER error

I found this thread and tried using regedit...
.exe files won't open

But my values were already set to the proper settings...and yet I still cannot get anything to run

Dave....
You say in Post 1

but my pc is in such bad shape

To give a hint, I did have some sort of virus issue in December and the issues started at that time. Norton now says I don't have any virus issues, but the damage apparently has been done.

IMHO Considering the multitude of problems you appear to have & the troubleshooting you have done thus far... the quickest & most reliable way to get your computer clean, up & running properly again would be to take a deep breath... & do a clean install.

Good luck.

FYI.
