My system: Windows XP Home Edition, 1.10 GHz, 128MB RAM. I checked and my computer is showing I'm only using 5.67GB out of 18.6GB. I'm not on a network. I have System Restore turned off (I've heard System Restore uses a lot of memory).
I ran defrag a week or so ago and earlier today scanned my computer for viruses (clean), spyware (clean), and adware (clean). I've used CCleaner to clean up .tmp files, cookies, etc. I followed the advice gerryf gave to another member who is also having a problem with a slow computer and installed ProcessExplorerNT. System Idle Process appears to be using most of the CPU.
Any ideas (besides buying a new computer)?
