I upgrade my PC with a RX 570 and now my computer is very slow, browsing is like 20 fps. I clean my drivers and installed the GPU, not worked. Then I format Windows, not worked too. Tried to use a another HDD, still same problem.I was thinking about upgrade my BIOS but is already upgraded. So I changed to my old gpu and it's normal now... what can I do to make my new gpu work?

Computer:

GA-78LMT-S2
FX 6100
8GB RAM
RX 570 / R7 260x
CX 500

Solved. After RX 570 was installed for some reason my reflesh rate changed to 72hz(my monitor is 60hz), so I just manually changed back to 60hz and my computer is back to normal :D
