I recently had to reinstall windows (Windows 2000) and I have found that my computer is acting much slower...like there is a program that is running badly taking up too much CPU power.However, there doesn't seem to be anything taking up too much CPU power on the Windows Task Manager except for Winlogon.exe. Also, when I activate the Windows Task Manager, the CPU percentage usually goes from around 90% - around 12%...any ideas on what this might be?
