Please Help Me With My Windows 2000 Server

HELLO ALL, PLEASE I JUST INSTALLED THIS WINDOWS 2000 SERVER AND I UPDATED ALL THE SERVER PACKS AND CRITICAL UPDATES FROM MICROSOFT BUT MY MEMORY IS ALWAYS USED UP AND THE CPU IS ALWAYS AT 100% WHAT CAN I DO? THANKING U ALL IN ADVANCE, HASCO

I’m going to move this topic to the open forum since the problem doesn’t seem to be malware / spyware related.
