i will say it once more ... Run an av scan play ET see how choppy ET becomes,That is just and example of what the md5 tool does but at intervals as morbit said set by a cvar.and it scans the ET folder increasing load on the hard drive seek.this is why it is at regular intervals that you experience spikes.
Other helpful tip's:
shut any other app's off eg msn.. run ONLY ET and see how that goes.You want the least amount of things to cause your hard drive to seek,Also defrag once in while.
