Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with TweakBit, please remove them as it may cause trouble.
An easy way to get remove these drivers is by using a restore point prior the installation.
System File Check
Please try following:
- Open an admin command prompt
- Copy/paste "sfc/scannow" (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.
Make a photo of SFC and post it.
