Well I just had to reinstall and rebuild myself. I must say I had a good run on what I have: Windows 2000. Oh about 2 years or more. With housekeeping.
My box is heavily loaded as well and usually performed well. Lately though the Windows Updates have broken key programs like Outlook, and IE. That may have something to do with some rogue virus out there :eek4: or not.
What I do is defrag regulary using the Systools from Microsoft. I highly recommend them. My two favorites among many others: For defrag; the contig.exe program is native, so it does not discomboble the file system.
For pagefile defragemntation I use is pagedfrg.exe and have it configured to run every time I boot. If you do go to Microsoft for the SysTools be sure to get the right versions for your Windows System.
Last but not least check out:

their software is very powerful....be carefull and it will serve you well. You can download the free versions at:

Be aware though that sometimes it cuts out broken registry keys because the software is broken or on the verge of breaking. For instance my most common problem is I have to reload AdobeReader afterwards...well it was not working right anyway...
Most of the problems (barring virus and broken software) are caused by heavy frags in both file and pagefile systems. Defragging the registry is a bonus and once you realize how many cruddy registry entries you have, you can understand the performance sluggishness. The first time I ran RegCleaner I had 700+ errors referencing crud that no longer existed!! Slug. Once I cleaned it up it surprised me how fast it was.
