Hey guys I bought a new motherboard and was installing it for the first time..the hahrdest part was to put the pins like (USB, PS/2, DVI, HDMI etc through the iron thingy at the back of case I don't know how it's called but it was pain in the ass I tried that like 10 times and scratched the motherboard at the top left corner around PS2 pins I know i won't be using them but I am still worried it could cause some trouble because I think I saw the copper but I don't know for sure I don't want to do it again but my PC is working just fine. So I don't want to unplug everything and check it out again just to be sure. Id it's bad what damage can it cause ?
