I have a headache from searching for solution of my problem.

Everytime when I open Google Chrome and any YouTube video (doesn't matter if Flash or HTML5), system process named "NT Kernel & System" goes to costume about 17% of all my CPU performance.

It assumes to 100% of 1 core of all 8 cores.

PC specs:

  • ASUS R500V
  • Intel Core i7-3610QM @ 2.30 GHz
  • 8 GB RAM

SW:

  • Windows 7 SP1 Home Premium 64-bit
  • Google Chrome 40.0.2214.91 m 64-bit
