Is it a laptop?
Touchpad can cause this. Turn it off and see if that stops happening. Is the mouse a wifi type? Check the battery.
Desktop, should've included that
Desktop PC, wired USB mouse
try the mouse in different usb port
unplug the mouse and see if the cursor will then move on it's own. If it stops, then time for a new mouse.
Keeps moving after unplugged and in different USB port
So not the mouse itself then?
I think the test would be.
I read JD's instruction to unplug the mouse and see if it stops. If you plug it in, you can't tell if that's it.
I tested it unplugged and it kept moving
I tested both it being unplugged and then plugging it into another port. Both produced a cursor still moving on its own
were you on internet at time?
I'm thinking malware at this point.
Should also ask if anyone else use this computer with a wireless mouse and left the receiver in it?
Yes, constantly on internet watching streams and playing
And no, nobody else uses this computer but me. No wireless mice ever being connected
drop the internet connection
actually unplug the LAN cord, or pull the wifi device, however you are connected, see if it stops moving then. If it does, then I'd certainly consider it a malware problem.
Unplugged ethernet cable and no change, still moves
Cursor still moves even without being connected to internet... I'm so lost
that makes both of us
just check to be sure no wifi receiver for mouse was put into a port by someone else. Reason I mention is I used to have fun with my youngest by doing that trick and when she'd be deep into Paint program, I'd turn on the mouse in next room and give it a circle and shut back off, just to hear her squeal, LOL. She got really good at computers and hacking my router 20 ways to sunday to get back onto it. I was actually glad she was learning. She's 19 now.
how old is this desktop?
I'm wondering if it's from the age of "bad capacitors" aka "capacitor plague", there's a wiki all about that.
Built this PC 2 summers ago...
Also, it's working fine now. Started up a game of Rocket League and when I was alt-tabbed during a game, it was working fine
Edit: Now its back...

Just a Thought... Have You Tried This?
Open the Control Panel, then the "Mouse" icon, then the "Pointer Options", then UNCHECK the box next to "Enhance Pointer Precision". Apply, then OK.
Hope this helps.
