CPU 100% maxed out (Only when streaming Flash Video sites)

Hi,

I've been having a problem with my CPU maxing out on sites that use flash video for almost a year now.
I've gone through all the checks for Malware and virus's using multiple programs from other members of a forum but no one has been able to help me as of yet.

The problem only occurs when I'm live streaming from a site that uses JW player 5.10.2295, I have downgraded my Flash player to an older version 11.1.102.63 on the advise from a poster on the adobe forum site.

I've recently ran a clean install and after only a day, the problem has started again, I'm using chrome browser, I have disabled the pepper flash plugin and I've also disabled hardware acceleration on the flash program.

The site that I use regularly is using the JW player to broadcast, There is High CPU usage for other flash sites(you tube, BBC I player) but my CPU is maxing out to 70/80 and the laptop is just about to handle it.

I've had my laptop for about 3 years now and it's always been able to stream HD content with no issues, I also have an old win XP and apple mac air in the house and it has no issues streaming from any sites with high CPU.

I would greatly appreciate some help to solve this, I have literally tried every thing to fix it, and the laptop might need to be kicked out the top window soon.

My laptop spec is below..

is everything up to date?? windows update, java version, etc ???
when your cpu is at maximum, what is the application that is consuming all of your CPU in task manager??

After I had a clean install I've been slowly updating windows 1 at a time to see what is the culprit, so it's not all up to date yet, but i've had this problem well before i did a clean install.

The application that is always at the top of cpu usage in task manager is always chrome.

This is only when I'm streaming live content from sites, (sport, football etc)

Java is up to date 1.7.0_09-b05
