Insufficient system resources on desktop

[JimD]

My machine is running XP Home, 2Ghz, 1G RAM. A firewall, anti-virus and
anti-spyware software are running in the background. It performs without
a problem for months, then starts behaving like this: This morning I
turn it on, open Firefox, Media Player and Thunderbird and work for a
few hours. Then I close Firefox and Thunderbird but leave an audio
stream playing. Three hours later I come back to a dark screen and move
the mouse to wake up the system. When I try to open Firefox (or several
other apps) a message box pops up saying "Insufficient system resources
to open (name of app)." After a reboot, all works OK again. Advice
please.

Check in control panel that virtual memory/page file system is set to
system configured (checkup on the net how to check this) otherwise
download a program called memtest86 and scan your ram for errors.
