Windows 8, Killer of Graphics Card? - Windows 8

Hello, guys,

The operating system of my Toshiba laptop has been upgraded to Windows 8. As everyone knows that the Aero of this system is quite cool enough. Though the computer is running well with Windows 7 Desk themes, it often gets stuck with the running of Win 8. I have thought it for a while. Perhaps my graphics card can not support the OS. Is that right?

Thank you for your help!

Windows 8 has a quite higher requierements on the PC configuration.
