In the BIOS lookup and the 3.3v, 5v and 12v values and post them in your next reply.
With the registry it can be due to some reasons so we'll have to do some diagnostics tests.
System File Check
Please try following:
- Open an admin command prompt
- Copy/paste "DISM /Online /Cleanup-Image /AnalyzeComponentStore&DISM /Online Cleanup-Image /RestoreHealth&sfc/scannow&DISM /Online /Cleanup-Image /ScanHealth" (without quotes) and press enter
- When it finished reboot your system
- Open again an admin command prompt
- Enter sfc/scannow again
If sfc/scannow says "Windows Resource Protection found corrupt files but was unable to fix some of them" after the second SFC, please upload the cbs.log file located at %systemroot%\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.
NOTE: this could take up to a few hours and sometimes may look like it is freezing, just let it run and do not open anything or use anything else to decrease the change of a random system freeze + make sure as less as possible is connected while this is going.
Make a screenshot of command prompt when this is finished and post it.
