Forgot to mention, the system is running Windows XP Home Edition, with Service Pack 2. Thanks again.
My father's Dell Dimension 4700 has slowed to a crawl for basic functions like looking at the disk size (40-60+ seconds) and the mere opening of Internet Explorer 7. I've uninstalled unused programs, eliminated a number of unused start-up/background programs via msconfig, checked for spyware (clean) using MS Defender, and defragmented the hard drive, and would very much appreciate suggestions on what else to do. It's got a 2.79 GhZ Pentium processor, 33 GB of disk (of which 11.3 GB is free) and 248MB of RAM.
Thanks in advance for any advice you can offer.
