My computer has been doing some wierd stuff lately. First there was a mysterious STOP error saying something about the page file using an area it was supposed to or something, now it always uses the page file, even though memory usage was below the amount of physical memory I had.....or so I thought until I went to run ccleaner to get rid of the 1.3 GB (!) of windows temp files, and it said my system only had ~240 MB of RAM (and I ran DXDiag to confirm it). Conclusion, based on that , I believe one of my memory sticks died, causing the STOP error the other day. I'll switch the socket on the remaining stick to make sure it isn't a socket problem, and then if it isn't then I'll go buy some new memory. If it is then I'll buy more memory anyway because this isn't enough.
