This first thing I would check is the contents of my TEMP directory, probably found in your Windows folder. As this folder fills up, you PC loses functionality. Delete all files with a .TMP extension. Any other files that are Excel, Word, etc. should be moved into a different folder. Then, clean out the Recycle Bin and reboot. If you are still getting LOW MEMORY errors, then you might check on how much hard drive space is remaining on the PC. Again, your PC efficiency is impacted by having too much on your machine. For best results, at least 25% of your hard drive should be free.
