|Tap key F8 while booting and see if you get the list which shows Safe Mode.|
If you can't get to that then you might have a hardware fault.
See if you can start in Safe Mode - it will take a while to arrive and look a bit odd. If so, go to Device Manager and see if there are any errors showing (usually red or yellow) under mice or keyboards. You can get to Device Manager by typing it in search.
Alternatively, if you can get to Safe Mode you could type System Restore in search and select a date before these problems came along.
Always pop back and let us know the outcome - thanks
