Noob needs help RIP

My computer keeps beeping and wont start up ....through trial and error i was able to deduce that my gpu was bad ...i tried a different gpu in the x16 slot and got the same debugging beep,i then tried it in the x4 slot and it worked ....so im guessing both the gpu and pci e slot are bad...can a bad gpu make a pci e slot go bad ? i noticed some green corrosion on the back of my card's pcb...can that corrosion short circuit my gpu and in turn make the pci-e slot go bad? FYI : motherboard asus m5a97 r2.0  GPU: sapphire r7260x ....THANKS IN ADVANCE

Pictures of the corrosion please, also yes a gpu can kill a pcie slot or vice versa.
