Why is my computer gaming graphics became slow after i removed my graphics card and re install back the same card that i have removed. i am using a gt220 graphics card and i have notice that my games became slower after what i did. Anyway besides doing that, i also overclock my cpu above stock speed just to test out the performance increased. I am using an pentium e5700 processor and a biostar g31 chipset motherboard with 3gbs of ddr2 ram.
