This is now the third time this problem has happened and it's driving me nuts. I've just updated to a new P4 1.7 and a new mobo as well.. the system is freshly formatted with a copy of Win2k on.. I've installed a few standard programs(winamp/aim/IE6/etc.) and now all of a sudden my processor usage will get stuck in a cycle.. It jumps to 20% then back down to 0%.. then 20... then 0. It spikes at exact constant intervals of about 4 seconds. Any idea what could be causing this ?
