[SOLVED] Everytime I watch a video my CPU Usage goes through the roof, videos are unplayable, especially in HD. Please help.

Recently everytime I started to watch a video I've had a lot of issues as they became unplayable, especially in HD. I noticed my CPU Usage has gone right up when I'm watching a video, it even goes up sometimes when I'm not watching videos like right now its at 30%-50% but then suddenly it drops to around 10%-20%. I'm really confused, I've tried everything from updating flash, re-installing Firefox, trying Google Chrome, updating my graphics card and now even re-installing windows and I'm still having problems. I've scanned for viruses, used disk cleanup/defragmenter and I've also had windows scan for malicious software.

My internet connection is fine, i recently done a speed test and was getting around 70mpbs download speed.

GPU: Geoforce GT 740
CPU: Intel(R) Core(TM) i7-2600 @3.4GHz
8GB Ram
Windows 7 Ultimate 64 Bit

UPDATE: I noticed in the processors svchost.exe was taking over 1,000,000 K and i was told to stop a service called Superfetch, that has brought the CPU Usage down and now svchost.exe is only taking around 16,000 K. But I'm still having issues with videos, they are unplayable in HD.

What videos in particular are you trying to watch? YouTube? Netflix? Hulu? Amazon? The latter three require software decoding (due to Hollywood paranoia about piracy), so will hit the CPU hard. A i7-2600 should be more than up to the task though. So if you're having problems with those services, I would check your power options to make sure you haven't accidentally switched the profile to power saving mode (which would limit the CPU to 800 MHz). Also, check in the advanced power settings under processor power management. Make sure its max performance is 100%.

If you're having the problems with YouTube, is Firefox the only browser you've tried to watch videos in? How about Chrome or IE? Have you tried switching from Flash to HTML5?

Try turning on/off hardware acceleration in Firefox.
Options > Advanced > General > Browsing > Check(Tick) "Use hardware acceleration when available"

Try starting Firefox in Safe Mode in case another extension is interfering somehow.

Yes the power settings are set to balanced, on the advanced power setting it says Minimum processor rate 5%, system cooling policy active and maximum processor state 100%.
