Port Forwarding

I've already got a desktop PC, and at the current state it just looks trash.. the Case is from 2003, i've upgraded a few parts but still need to get a New CPU + More Ram, I'm thinking of getting the i7 2600k but i don't know which motherboard would fit it, i'd prefer one that supports ddr4 Ram...

My lap top won't turn off. The fan is running the external mouse light is still on. The last thing I did was update then it crashed so I pressed control alt delete to shut down. From there I have a black blank screen!!??
