Arrow Keys not working in MS Office, Scroll Pages & Moving Cursor left and right

[uthayya]

I've seen quite a few other posts that have the same problem but pressing F7 /+ F4 and/or Scroll Lock (with Fn also) doesn't solve the problem for me.

I know my arrow keys work because when I press Fn + the Arrow Keys OR Win + Arrow keys I do get the desired result (volume/brightness control and splitting my screen). However, I just cannot move from one cell to another on Excel and I cannot move my cursor left and right while typing. Neither do webpages scroll anymore.

All was working until an hour ago and it just randomly stopped working.

Any help is appreciated.

TIA

is it a PC or laptop? Is it brand name or custom?

Try a clean boot and see if it helps - if so, it must be one of your start up programs, slowly add them to find cause: https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows
