tantly flashing

Keyboard

Keyboard not working at all,Have Constant Flashing Blue Circle Next To Cursor (Arrow) Drop Down Menu's Don't Work.

 

Mouse not functioning after upgrade

The touch pad no longer functions. I must have a usb adapted mouse in order to use the cursor. As well, there is constantly a blue circle beside the arrow flashing on and off. The task bar is also flashing at times. I am not sure as to why all of this
is occurring. Thank you for your help.

 

It shouldn't be constantly flashing. When you click on a file or program, the little Busy circle shows up for a split second as the computer Thinks as it starts to load the file or application. Solved Constant flashing loading icon (blue circle) next to my mouse. - Windows 10 Forums

 

Any new system install will tend to generate a lot of activity at the start of use, Windows uses a number of databases for use with Searches Etc. These need to be populated and this is performed as a background task, which would explain what you are seeing.

I always try to leave any new system on for a few days after install to allow this set-up to complete if this is possible. but if you only use the system for tasks during this time and especially if you have a complex system with a lot of data it may take a while to complete.
