Can no longer see brush, eraser or any tools. Caps lock is off.

Do these screenshots tell you anything helpful?

Make sure your computer meets the minimum CPU & GPU requirements to run Photoshop.

Thanks for the suggestion. It was already unchecked. 

I have the same install on my personal laptop and everything works perfectly so this is obviously an issue relating specifically to my work laptop. I think I have a graphics processor issue. 

Go to Preferences > Performance... and uncheck Use Graphics Processor. Restart Photoshop. Does the problem persist?

Update: I can see the mouse pointer show the brush when I increase the brush size to 500 px or more. But that's absolutely not use. I need to see it at all sizes.

I'm also having issues in InDesign - I cannot resize shapes. It's not possible to grab the corners of selections or shapes to grow or shrink them. They just rotate or move around. 

Changing to a different mouse does not help.

It sounds like there is something in CC that is not responding to my mouses correctly.
