I'm sure that I can't be the only person that this has happened to so thought I'd share the solution with some chums. The teccy IT help sites have lots of queries about it from frustrated users but numerous different answers, only one of which eventually worked for me :)

Some time ago the screen of our desktop PC began to "jump" (I mean the image not the whole monitor !) Not much, just a quick jump up and down a couple of centimetres or so. Inconsistently too, because it also worked fine for long periods. Over time it began to jump up and down more, again inconsistently.

In recent weeks it became demented :steam: Navigating web sites requiring any degree of sensitivity over selecting fields or functions became impossible. By now I was getting randomly paged back involuntarily. Reading was immensely frustrating, loads of emails were aborted and attempts to use sites to buy items became risky. It was effectively scrolling itself as if operated by an invisible toddler. The teccy web sites (which were torture to access and read under such conditions) offered various solutions ; complex adjustments to Windows settings, downloading new drivers, several antivirus search / removal recommendations, moving speakers away from the monitor and suggestions about the monitor itself :scratch:

Just to be clear, it wasn't the screen, it was the Window self-scrolling. Eventually after a complete reload of Windows didn't improve things my wife began talking about getting a new PC altogether.

I happened to try a new mouse - it has worked perfectly since.

Strange, sometimes my mouse curser wanders across the screen on its own accord.

Dont matter now as you bought a new mouse, if it occurs again give a good clean and a blow out (I said "out" dammit) with a tin of compressed air.

Or, if your like me, turn it upside down and whack the shit out of it.

The errant mouse issue happens a lot with laptops as the strain gauge mouse controller in the centre of the keyboard goes awry...

Glad you solved it Pete - it is often the unexpected that causes the problem in my experience.

One of the oddest issues I've ever seen was a laptop at work where the keyboard would type itself! Very spooky. I exorcised it, then locked it in a cupboard, until another one of the same model blew an optical drive. Robbed the "possessed" one of it's DVD-ROM, and guess what happened to the one we put it in? How an optical drive can cause random key "presses" I will never know, but two new ones later and both machines were back up and running. :confused:
