You could be having a problem of DoS(Denial of Service). It may be a Trojan or whatever. Your problem sounds just like I used to have and it drove me crazy.

Please clean the wires or the ports as dust could also be a big problem. btw you seem to have a large amount of free HDD space.*I am envious* The good news is that I have got a faster connection now and hopefully I would enjoy a better online experience.
