Books?

Any specific books i should read to get more into computer hardware? Im 15 i have built 4 computers. One of my own and 3 for friends. I know the ins and outs i just need to go well deeper. Anything specified towards the architecture of processors and how motherboards work would be great! P.S. i didnt know which forum to put this is so lets try general!
