If a PC is "RAM limited" and the option of living with the current amount of RAM rather than upgrading is chosen, what are the best tools/methods to reduce RAM usage. Basic PC Information (Taken from MyComputer Properties): Compaq Presario, AMD Athlon XP 3000+, 2.16 GHz, 448 MB of RAM, Windows XP Home, C: Drive: 147 GB, Free Space 126 GB. I am somewhat familiar with tools like Windows Task Manager, Microsoft Process Explorer, Microsoft AutoRuns, MSConfig but have never used them to do things such as permanently remove some Windows Startup Entries. I have not yet fully evaluated the PC to make sure that RAM limitation is the problem. The hard drive activity is almost constant. The PC is super slow. I was eventually able to run an "Express Scan" with Dr.Web Cureit in Safe Mode. No Malware was detected. Yes, I know that I still need to run a hard drive diagnostics from the manufacturer's bootable diagnostics CD. I just haven't yet gotten around to it. The PC is located at someone's house about 25 miles away. Thanks in Advance.
