Using mouse causes high CPU usage in explorer.exe (Windows 7)

[BAZ]

Recently, I've noticed that while i'm playing games my game seems to lag whenever I move my mouse. I didn't think much of it until I tried playing a game with my tablet. When I play games with my tablet my FPS is constant but as soon as I move the mouse my fps drops by around 40.

I opened task manager to see what was slowing down my PC when I move my mouse, and noticed that when I move my mouse my explorer process jumps from 1-2% to 16-20% CPU usage.

The mouse i'm using is a Microsoft Habu and I've reinstalled drivers and had the same effect. What could be causing this?

My PC specs are:
AMD 4600+ X2 (A bit lacking I know, but 20% CPU usage for a mouse?)
4GB RAM
8800GTS

Sounds like a faulty or poorly coded background program that's responding to mouse movements.

Do you also get fps drops when not using your tablet?

Buy a new mouse dude. A cheap laser would do.

I'd recommend getting (or borrowing) a cheap mouse and see if it happens with that as well.

That way we'll know whether it's a badly coded program or not, like Robber suggested.

I don't get any FPS drops using my tablet, or when I don't touch anything. But as soon as I touch my mouse I drop 40fps.

Gonna try a cheap mouse see if I have the same problem.

Try uninstalling the mouse drivers (if you have any) and check if it makes any difference.

Ok, just tried with a cheap mouse. I do not have the same issue on a cheap mouse.

Gonna uninstall mouse drivers and see if I have the same issue.

Uninstalling mouse drivers yielded no differences.

Does the game still lag if you close explorer.exe?

Wow, I thought everyone had this problem. Same thing happens to me.

Strangley no. Closing explorer.exe when I play a game keeps the fps constant and smooth. This wasn't the case a few weeks back.

even 40fps is acceptable, gurantee it's the CPU or Ram struggling to run a program or keep it responding, scan for viruses and spyware.

OP, did you have the latest drivers before you uninstalled them?
