When I play YouTube video at 720p, the buffering process takes too much resources from my notebook. The only way for me to watch the video while it is still buffering is to shutdown all programs running on my computer, including antivirus and win defender. Because the buffering itself requires 99% of my CPU for some weird reason.
If I have a program running which takes only a few % of CPU, the video would not play fluently while buffering and the program would probably go hung (the window turns white). So I just have to wait till it's buffered so I watch the video.
Is this normal on older weak CPUs? Isn't buffering the same thing as just downloading the video into RAM/HDD? And is there any way to fix this? Once buffered, I can play the video fluently even with other programs taking CPU.
Also, when I buffer longer videos, after 10 or 20 minutes or so the video gets distorted into green noise, making ugly hi-frequency sounds and jumps slowly to the end.
How did that happen and what can I do about it?**
I use Google Chrome and Intel Mobile Core 2 Duo SU9400 @ 1.40GHz with integrated graphics.
