the virtual memory isn't going to fix anything, there is a conflict between the BIOS and your OS. I'm assuming you have Windows XP or 98.
You can only have 1 thing controlling your computers stand-by, the BIOS or OS. Your choice but I prefer OS. Go into your BIOS and turn off the limit of time your computer is idle before going into standby, that will give the OS control.
Goto the control panel then Power Options to control the standby time through the OS. If you select the stanby time as NEVER, then the BIOS will control the standby.
If both are turned off, the computer will never go into standby, and if they are both turned on the BIOS will fight the OS for control.
