OK, before doing anything, I suggest updating your Windows. Go to Control Panel > System and Security > Windows Updates > install everything you can and restart your PC.
Also, update your Graphics Drivers (when you don't have a video driver, everything works a little slow, you can check it out by opening the browser you are using and slide it over your desktop from left to right. If it slides in frames then probably is your video driver). To update your graphics go to Start > type Run > type in Run DxDiag > and search for your video card manufacturer on the Display tab > go to Google and search for your manufacturer (I.E: ATI/Nvidia drivers).
Go to their official website and get the latest drivers available for your Graphics Card > install it > restart your PC.
Also, update your DirectX, link bellow:
