Do you mean that sometimes it freezes but then recovers?  If so is the
disc light flashing continuously?  If so then you have probably run
out of RAM and it is continuously swapping memory onto disc.
Run top or the system monitor and keep an eye on swap, if it starts
using a significant amount then you need more RAM.
