An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.

Update this driver and see if that helps.

Sometimes drivers remain and do not get completely uninstalled.

 Driver Removal Process:

  • Download Driver Sweeper to the desired location.
  • Extract the files from the zip.
  • Uninstall the driver Program & Features - Control Panel.
  • Run Driver Sweeper, check the drivers you want to uninstall or clean registry leftovers of.
