I was just installing a 212 evo cooler master to my computer, because after. 3 months with my computer i decided i needed a better system fan, anyway when i installed the fan and turned on my computer the ethernet controller was not working. So i uninstalled the ethernet controller and reinstalled it, no luck its the right file because i used it before. It asked if i was in deep sleep mode, and please plug, or something like that. My question is did i accidentally damage something on the motherboard that would cause it to not work? PLEASE I NEED HELP!
