Hello and welcome to TomsHardware.

It's hard to see how a mouse could cause that spike in Explorer's CPU usage, if it is a spike. Do you ever look in Task manager when the mouse isn't slowing down? I prefer to think Explorer has a problem and the mouse is just the messenger.

When a system slows down to that extent, I start to suspect malware and suggest you run some scanners to see if you've been infected. For starters, download MalwareBytes from http://www.malwarebytes.org and install that. Let it update and restart itself then run the Quick Scan and when it completes, check all the items it found are ticked then click on Remove Selected. Click the Logs tab and copy and paste the log back here then restart the computer.

Best to download MBAM and run it in SAFE MODE w Networking.

When started the problem? maybe you bought a USB optical mouse?
This happening to me too but not so heavy. My solution was to buy an PS2 optical mouse.
Now, if you have and virus or trojans thats another case.
(USE FIRST: COMBOFIX I mention in end)
Additional to malwarebytes use AND a antivirus program to make a full scan to your computer. Use for example the 1 month free trial NOD32 from www.eset.com.
Also use AND the one-use antivirus COMBOFIX (do not use the recovery console that will offer) http://www.bleepingcomputer.com/combofix/how-to-use-combofix
