Things I would try to do to fix the issue...
#1 Reflash the video cards vbios.
#2 Use
DDU to clean out your old video drivers.
Do not reinstall your drivers after performing this step. Do step #3 after using ddu. #3 Delete video guid's using regedit. Click the start button and type regedit and hit enter. For windows 8/10 hit the windows key + r and type in regedit and hit enter. Navigate to...
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video (highlight the Video key and press the delete key.)
NOTE: When deleting the video key you will be prompted with an error saying "Error deleting key, Cannot delete Video: Error while deleting key." Just ignore the error and select OK, all keys within the Video key will be deleted except for ones that cannot be deleted. Restart pc after deleting the guid's. #4 Download & save the most recent graphics driver to your desktop. You can find the most recent graphics driver
here. Run the graphics installer located on your desktop once the download is complete. Select custom advanced install, under custom installation options uncheck all options except graphics driver & physx system software, if you have a 3D capable monitor and would like to use 3D at some point please select both 3D options, check mark perform clean install, then click next to install the driver, reboot when asked.
If you're still having issues at this point I would suggest doing a clean install of windows. If a clean install of windows doesn't fix the issue I would recommend sending the laptop in for service.
