One possibility seems to be connected to your Antivirus S/W which needs to be updated.

I have a new Compaq Presario X1010 with 512MB Ram running XP Home. When I leave my computer on overnight to do scheduled tasks the next day the screen is blank and the system is hung. After I restart and check the event viewer I see this message repeated many times. "Srv Event ID 2019". "The server was unable to allocate from the system nonpaged pool because the pool was empty". I hope someone can help me out here, I have tried two other forums and spent hours on the microsoft site to no avail. Any help would be greatly appreciated.
