Mouse jumping around/ moving on its own - usually after playing games for about 30 minutes

Today I was playing a game, Endless Legend, when my mouse started zooming in and out really quickly. At first I thought it was just me touching the trackpad accidentally, but it carried on even when I wasn't touching the PC. I even unplugged my physical mouse and the problem continued. Later on I checked, and my trackpad had been disabled the entire time.

Eventually I deleted my mouse drivers for the trackpad and the physical mouse, updated windows, and restarted the computer.

Now the problem is much better, but still remains in a slightly different form - the cursor jumps around and moves slightly upwards almost constantly. Before it was a problem with the scroll, now the cursor itself is moving.

I fired up Endless Legend again and noticed that the jumping was more intense while I was playing. When I closed the game down the cursor stopped moving and is now (almost) completely still.

Really strange. Does anyone have any ideas about this one?
 


My GPU temp was going up to about 90 degrees celcuis, though I'm not sure if thats good, bad, or normal.

I didn't try lowering the graphics, because this is happening on games where I've never had a problem before. This just started one day out of the blue.
