I own an original Windows 7 OS, and downloaded the update for Windows 10. After installation of files comes the installation of drivers and related files. The computer then reboots into Windows 10 bootscreen and I get a BSOD with the error message "page fault in nonpaged area." The computer proceeds to reboot a few times trying to recover the installation, then recovers the original OS. I have tried to fix this by modifying certain cache options in the system's properties. I have also ran an in depth hard drive scan. I know this error message could be due to a bad driver or a bad RAM, but I have failed to identify what is the error's source. Note that I am not getting this error with the Windows 7 OS.
