Hi there and welcome to
CompuForums! I hope that you continue to visit us, even when your problem has fixed.
Have you tried removing everything in Safe Mode? When starting your computer, press and hold F8 when your computer has just finished BIOS [usually the logo of the maker of your computer appears during this]. It may take a few tries, but when the Windows Boot Menu comes up, select Safe Mode.
When in safe mode, your computer's monitor will not display all the colours, and it's resolution will be low. Other devices such as audio and printers may not work during safe mode - this is normal.
Try deleting everything in safe mode then reboot your computer. Let us know if this fixes it or not, and if not, we will look into other fixes.
