Has it always been so slow or is it something that started lately. If it started lately, can you remember if it followed some specific change, like a software installation?
128 Mb of memory isn't much at all but I saw many computers with the same specs running XP much better then you describe your computer running win 2000..
Please uninstall your antivirus and see if it makes any difference. If it doesn't download and update the following programs: Ewido, AVG antivirus, Spybot, Ad-Aware. Start the computer in safe mode and run all of them, one after the other. In Ewido and Ad-Aware choose to run complete scans. Please report results.
Check how much virtual memory was allocated in your hard disk. I recommend 300MB at least. To check enter: control panel > system > advanced > click settings in "Visual Effects ........... and virtual memory" > advanced. At the bottom of this page you can see or set virtual memory.
