I will provide very simple solution just roll back to the changes you have made to your registry this will provide you all your previously changes or you may have set the restore point for your computer roll back from there this may also help you

Try to Boot your system to Safe Mode.
Click START, RUN, type DEVMGMT.MSC and click OK, there you may found the display adapter expand it, Uninstall listed display adapter when asked to remove the hardware. Now Restart the computer normally, and Windows will automatically reinstall your graphics driver, which may clear up the issue (at least temporarily).
