Slowness when moving my mouse

[Kitteh]

About 2 months ago I noticed that my computer was starting to slow down when I played certain games and when I watched videos. At the time my hard drive was making horrible noises, so I went and bought a brand new one thinking that was the problem and nothing has changed. Tonight however, I discovered the problem. When I move my mouse around my CPU usage goes up to 30-50% from 0-5% when I am doing nothing. When I am watching videos on websites or playing games, it goes even higher causing everything to lag. Could this be a problem with my CPU itself? Or could this all be in my head and be a problem with my video card?
Any input is greatly appreciated.

Have you defragged it? Ran Ad-aware by Lavasoft to make sure you haven't contracted a nasty spy/malware? Or have you run AVG free virus scanner? Or whatever anti-virus software you have on your computer?

[Kitteh]

My computer is totally free of any spyware/viruses. The problem continued as soon as the new HDD was ready to go. Also, my webcam doesn't work. When I turn it on, it works for about 30 seconds then shuts off and won't work again for a while. So I have been wondering if its my video card...but people are telling me it could be my CPU. I'm just really stumped. I'm starting to rule out my hardware piece by piece but not having spare parts around to test with, it gets costly.
Overall, the computer is running smoothly but the problems start with my mouse causing my CPU usage to soar.

Minor question but ...... is this mouse a regular (type) MS wheel mouse or other.  Any changes in system re additions etc?  How old is mouse?

It'd be useful to know if another mouse produces same troubles.  Mouse activity as you no doubt realize, should not place great work on CPU.

...and what Windows version is it?

[Kitteh]

I'm using the Logitech G5 laser mouse, have been for almost 2 years, my problem just started out of the blue a couple months ago. I am running Windows XP Home.

Try different mouse.

Try different mouse.

And maybe a different surface.

[Kitteh]

Ok, I tried a ps2 optical mouse and a different surface, no change. I was under the impression that if the CPU doesn't work, it just doesn't work at all. I could be wrong and maybe it is going very slowly?

When I move my mouse around my CPU usage goes up to 30-50% from 0-5% when I am doing nothing.

I did a search online and apparently this may result in a virus infection, or another running process.

I suggest posting a HijackThis Log.

The log looks clean.
You need to update Java:
http://java.sun.com/javase/downloads/index.jsp
Java Runtime Environment (JRE) 6 Update 7
Uninstall all previous versions of Java through Add\Remove.
I don't think, it has anything to do with your mouse problem, but you need to do it, anyway.

What exact process is listed in Task Manager as the main CPU taker?

[Kitteh]

Thanks, I'll update. System Idle Process as main CPU taker.. There is nothing odd running, or using too much. I've been researching alot on my problem but can't seem to find any real cause/solution to this problem. I may have to buy a cheap CPU just to see if that is the problem. So far though, I am not making an progress. 

[Broni]

System Idle Process as main CPU taker..

It's NORMAL. System Idle Process is a percentage of CPU, which is NOT used.
At this moment, mine floats between 80-90%.
