Gameplay performance problems [CPU AND RAM]

[Lanysia]

Hello everybody,

i have some problems with my CPU performance and my RAM performance.

Even when i listen to music via youtube and play World of Warcraft at the same time, my laptop gets stuck. he lags very hard, i had toplay then with 5-6 FPS. Problem is, that seriously my laptop should be good enough to show world of warcraft in high end graphic but these happens also when i play at low details setup.

Here is my system:
Windows 7 32 Bit Home Edition
Laptop: MSI GT 628
CPU: Intel Centrino Dual Core 2x 2.6 Ghz
RAM: 4 GGB
Graphic: NVIDIA Geforce GTS 160M

Installing a new audiodriver did not help.

Please help me.

Would it be intelligence if I deinstall Win7 and instal WinXP?

Also here is a screenshot:

Are you playing with your browser minimized? I also assume you are playing in windowed mode?
I see you are using firefox, I would suggest downloading google chrome and giving that a shot. I'm not asking you to switch your browser but just experiment. You could also try to reinstall flash, should you go this route uninstall first, opposed to installing over your current version.
