I've been spending the last five days fixing up this computer. It's 5 years old and until I defragged it and fixed it all up, it ran like [cabbage]. Now, it works great. Except I cannot get runescape to work properly. It takes me 20-30+ minutes to load the login page, and another 10 to login and try to do something before it force disconnects me after massive waiting times. Can anyone offer any help?

Bit of an update. I got it to load the login in ~10 minutes now, but I still cannot do anything without being kicked off of the game.
