PC continually pausing

Question

A few weeks back I noticed the mouse cursor started "pausing" as I move it around. It stops then rushes to catch up. It does this continually - every 3-4 seconds. I tried several different mice - wireless and corded - all do the same. Now I notice its actually the whole PC that's pausing - video display etc. 

I searched online for solutions to the mouse pausing and nothing worked. I even bought a new SSD and did a fresh install of W10 to it and the mouse seemed to be working OK while it was installing, but as soon as the first welcome/browser screen was displayed, the pausing was back. 

I've reverted to my original boot disc and now just tried safe mode and in that the system is OK - no pauses. How do I work out whats causing the problem ? Which driver/service/app ?

Answer 1

You install drivers using the same steps as this article describes for software applications.

Answer 2

No my drivers do not include Catalyst - maybe because they're a bit old. 

I have Radeon HD8400E. Yes its an AMD GX-420CA SOC with Radeon(tm) HD Graphics, 2000 Mhz, 4 Core(s), 4 Logical Processor(s). 

I can't find the HD8400E listed on the AMD drivers site but they have an auto-detector and installer which runs OK and installs 8400E drivers, but the same problem results. I got the original drivers from the supplier of my PC - a fitPC4. 

I haven't tried installing in compatability mode - how would I do this ?

Answer 3

Did you find AMD Catalyst Install Manager?

From what I understand when you install the drivers the AMD Catalyst installs with them.

Do you know which Radeon version you have? This is a list of those not supported by Windows 10.

Is your Processor also AMD?

Have you tried installing the drivers in compatibililty mode?

Answer 4

After heaps of searching I can't find anything relevant for fixing the atikmdag.sys problem. It appears to come from AMD/ATI graphics drivers, which haven't been updated in ages, so I don't understand why its only started happening now. Maybe I should work my way back through recent windows updates and undo them ?
