I was directed here from the Windows 10 support section because I may have a virus or similar issue:
I have Malwarebytes Premium and Norton Internet Security which have both been running fine as far as I can tell but my PC experienced an issue several days ago.
Multiple times in a single day my PC displayed an all white screen, only the mouse cursor was visible and I was able to move it. The first time I noticed this was after an idle period (more than an hour) I rebooted the PC but the white screen returned upon startup, I could not even get to my Windows profile. 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 Internet Security 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? My PC is an all-in-one and about 5 years old. Is it possible it could have been a screen display issue or more likely a virus/malware issue?
One last thing I could mention is several months ago by PC began shutting itself down during the overnight hours when not in use. Since I updated to Windows 10 this has not happened.
