Audio and video on my windows 7 machine is suddenly choppy

I've recently found that audio played in browsers of players such as Windows Media player is recently choppy from time to time and it's as if the speaker or singer is stuttering. The same is true with plain videos also. How can this be corrected?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

First two things that I would check  are CPU utilization and HDD for bad blocks. CPU utilization you can see in task manager during stuttering, and bad blocks in event viewer (Windows logs/System).

The choppiness occurs when the cpu usage is not near maximum and no hdd problems appear in the windows event log.

It seems that cpu utilization is the problem but Windows Media Player and Firefox are taking a huge chunk of cpu. Wmiprvse and searhindexer are also using much of the cpu.

When things suddenly start to go wrong first check for spyware.
For a quick scan I use hijackthis.
It is in zip so download to a folder and extract it to that folder then run it and do a system scan and save a log, attach the log back here. The scan takes around a minute.
Then run a disc cleanup and delete cleanout temp files when temp files get large windows cpu increases as well.
I also use the free version Ccleaner to cleanup my system

I found the problem to be high cpu utilization. I switched from Avast free antivirus to Avg (for other reasons) and the utilization dropped and the problem has stopped
