I have a Lenovo Z710 ideapad running Windows 10 with all the latest updates as well as driver updates. I have also run a full virus scan (avast), have minimal startup items, and have run the tweaking.com repair tool. I have also uninstalled all the software items I do not use.
Randomly, usually upon initial startup or if I leave the computer for a while (and i have mine set up to never sleep or hibernate), the taskbar or desktop suddenly become unresponsive. I hover my cursor over a quick launch or desktop icon and the translucent box that would indicate you are over it does not appear and clicking it does nothing. Other times, open windows will be frozen as well and clicking to minimize or close the window does not work.
No matter which of the above things occur (oddly, it is usually just one - like just the taskbar or just the desktop icons), I have to press ctrl/alt/del, click the left-hand mouse button anywhere on the screen, and select "cancel" for things to start working normally again. I have no idea what the connection is between an unresponsive taskbar or desktop and simply going into the ctrl/alt/del menu.
Unfortunately, I do not know specifically when this started, so I cannot associate this issue with the installation of any specific software or driver update.
I have done extensive searches on the internet but could not locate anyone with my specific problem.
I am at the point of needing to reinstall Windows as that is how irritating this is.
Sorry if I left out any important info.
Thanks in advance for any thoughts or help.
