Accidently unplugged a loose cable from my modular power supply while putting my led case fan back in the Velcro spot. When the cable came out my whole system shut off. When I replugged it and booted back up. However I now have no display and my mouse and keyboard will not work in any USB (case or on mobo). I am still getting power to these ports however is it barely there (enough for my phone to think it's charging when in fact is is not.) I have replaced my PSU thinking that was the problem and I still have the issue. Could this be ram related or did I really mess up my motherboard?
 
Hi and welcome to Tom's forum.

Since you already used another PSU with the system and the problems is still present, I would think that your motherboard has passed away. Try removing the CMOS battery but I really think that you will have to change the mobo.
