I have a Windows XP SP3 Professional OS running on a Dell Optiplex GX270. When I'm working with Visual Studio Express (a programming IDE), Google SketchUp, or any other resource-heavy program, my virtual memory takes a nose dive within about ten minutes of launching the program, and I get one of those notifications that Windows is adjusting the VM.
If I attempt to run two of these types of programs at the same time, my VM drops down to nothing, and I have to hard-reboot.
What is wrong, and how do I fix this? It is getting really annoying.
