Disciple
My mouse(Deathaddder essential) kepps on moving itself(jumpy). it majorly keeps moving to top left corner of the screen.

I would like to know what thing is at fault here and if it is possible to repair.
I have checked that it is not a driver or virus issue.
I like the size and grip of this mouse

Also, can someone suggest a good budget repairable mouse with atleast 3 buttons.I can do soldering if needed.
I like to keep things as long as possible and not contribute to ewaste problem.

I don't do gaming.
I like the size and grip of this mouse.(Don't like small mice)
 
Disassemble the mouse and clean it thoroughly. The sensor, prism, etc. There would be dust and tiny strands of fabric stuck in the rotary encoder too. You'll need a magnifying glass or mobile camera to spot them as they are almost translucent. You can use IPA 99% and a flat paintbrush (number 8 to 12) to clean these tiny areas. If you are comfortable with opening up the switches, then do so and clean them too. They can be tricky to reassemble. I generally douse the switches and rotary encoder in electrical contact cleaner.

Do you think cleaning will resolve the mouse moving to the top left corner on its own issue? I can understand cleaning can help with double clicking and irregular scroll wheel issues.

I used cleaning to get rid of scrolling issue problem some months back but not sure about this one. But will try it anyways.
