Multiple times today my PC has displayed an all white screen but the mouse cursor is visible. The first time I noticed this was after an idle period (more than an hour) I rebooted the PC but the white screen returned, I rebooted again and it was gone but the PC took longer than normal to load windows. The PC then ran for several hours in a "normal" state (I didn't notice any issues but I'm a novice) however after an idle period (more than 30 minutes) the white screen returned. Pressing Ctrl+Alt+Delete brought the desktop back up (I did not attempt this the first time) and the computer once again appears to be running fine.
I ran my Norton antivirus and Malwarebytes full scans in regular mode and the MBAM scan displayed several PUPs from "mindspark" which have been removed.
Can anyone direct me where I can go for help. Are they any files/reports I can post that will help diagnose the issue?
