Computer started to lag massivly after Graphic card change

[Seskom]

Hello, I am asking help from here cause lines at computer workshop are like half month long, the situation is that my Graphic card 8600gt got changed to 9500gt and after this my computer started to lag massivly, I formatted my PC wich didint help, I downloaded newest driver from www.nvidia.com but nothing helps

Even simple things lag for example audio file running alone LAGS some times abit, If I open network too then it will start to lag massivly and theres not a thing I can do about it. Maybe someone has had same problem in here and could help me cause I really dont wanna wait half month at repair again...

btw I called them and they said 9500gt should fit my computer and they got no idea what causes this.

Since the company said it should fit then I belive problem is in something else

Why you even changed from 8600GT to 9500GT? its actually worse, just new chipset.

Late reply, but will reply anyway..
8600 GT is better than 9500 GT... Go to the store and tell that to them if they didn't know it..
WHAT ARE THE REST OF YOUR COMPONENTS IN YOUR PC? No matter what the guy in the store says, if you have a problem, you tell the components to us IF you want any help..

Try this too: Un-install drivers with (example driversweeper) and install newest graphics drivers (no, uninstalling it from control panel or nvidia's own uninstall won't uninstall them "totally")
