We happened to discover that My Computer|Properties indicates that I have 384 MB RAM, not the 512 MB that's really installed. If something is preventing 128 MB from being usable, I would suspect more paging activity than usual. I have the page file on a different logical disk from the O/S. (I have both the C: drive and a D: drive defined, but only one physical HDD so I think the HDD must be partitioned into two logical drives, although I don't know how to confirm that). The system is managing page file size. Can someone provide help in finding out why this RAM is missing?
I just discovered something else interesting. Running sysinfo shows that Total Physical Memory is 512.00 MB but Available Physical Memory is only 96.96 MB. What's up with that? No applications are running. Who's using all the RAM?
