i'm greg, volunteer installation specialist , 8 year windows mvp, here you.

check newer display driver on pc or display adapter support downloads webpage. while there check if there other newer drivers update. can take time until updated.

there known issue of incorrect display driver being pushed windows update requires rolling driver. right click start open device manager, choose display device, driver tab, roll back.

if there no roll or doesn't choose update driver on display device driver tab, browse computer, let me pick see list of installed display drivers, work backwards trying each find 1 works.

if necessary can go settings>update & security>windows update driver under installed updates , uninstall form link there. can hide driver isn't pushed again using hide updates tool downloaded here: http://download.microsoft.com/download/f/2/2/f2...

if none of work try system restore point before problem began: http://home.bt.com/tech-gadgets/computing/how-t.... make sure system restore enabled c plenty of disk space apportioned (5-10%) in configuration settings.


hope helps. feel free ask questions , let know how goes. keep working until it's resolved.
