Try going into Safe Mode
As soon as the BIOS has finished loading (the first screen on the pc showing the Drives etc), begin tapping the F8 key on your keyboard. Continue to do so until the Windows Advanced Options menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
Using the arrow keys on the keyboard, scroll to and select the Safe mode menu item, and then press Enter
Do you get to see the desktop?
