I went to stand up and I accidently put my hand on my keyboard and pressed quite a few keys, some tab came up and quickly went away and my desktop has completely no colour. I have updated drivers, reinstalled drivers and done a few of the basic things others have suggested to fix it and nothing. When I restart the computer, all the opening moments are in colour. It's only till I log in to when it loses colour. I have a GTX 1060, Core i5 7600. Can anyone help, as I desperately need to do work and I require colour to do so.
