I have random problems with flash videos for a while now. After playing a while they have a very low framerate and consume maximum CPU. This happens on youtube, vimeo and with most other flash based video content. Its on chrome and Firefox and happens more frequently when in fullscreen.
If it happens, my whole computer is slow, windows building up very slow and I can barely move my mouse and other tasks like skype.exe also use maximum CPU. After some time I am able to kill the flash task or chrome and it works again. But its super annoying and I have no idea what could be the cause... Any ideas? could it be a virus? or a bad BIOS? graphics driver?
Hardware is a Vaio VPC-Z1 with i7 quad core 2,8 GHz, nVidia GT330m 1GB, 8 GB RAM and SSD disks... so it should really be no problem to play flash videos, even in full HD.
