my computer is very slow when I install nvidia geforce gtx 550 ti graphic card.. When I change back to onboard card everything is ok..and when I try to install again it's the same problem.. I tried reinstalling my windows, updating graphic drivers and scanning for viruses but it didn't help..
I have psu 550w, AMD Athlon(tm) 64 processor 3200+ 2 GHz and 3 GB ram
