I wouldn´t think the DHCP problem would be related to the hard disk activity.
Open a console and type ´top´, that will give you the process using most CPU.
On the 3rd line, look at the number before "wa" (I/O wait): it should
be close to 0%, otherwise some process is using your hard disk. It
might be the one using your CPU, but then it might now :-(

Finding the culprit might be difficult, unless there is something
obvious (look at swap usage on line 5).
