I have been having a relatively major issue with my Windows 10 laptop. Every once in awhile, the desktop and taskbar will just disappear for 5 minutes or so and then come back. It seems to happen a lot when trying to adjust the volume. Before it goes away, when I hover over the taskbar, I get the spinning circle, just over the taskbar. Any ideas as to what this could be, and a way for it to be permanently fixed? Also, it should be worth noting that I upgraded to Windows 10. The computer was originally loaded with Windows 8.
