Process eating up memory

[Computer noob]

explorer.exe is constantly using 60-100% of my cpu, and if that ever drops to like 50, then its rundll32.exe thats using up the rest of it. Ive tried just ending rundll32, but then windows practically crashes, and same with explorer.exe. Can any1 help me out?
