Possible Solution
Memory module is not the correct type or speed grade for
the system. Replace module with the correct
industry-standard device for the computer.
1. Memory configuration may not be set up correctly;
check memory configuration using Device Manager.
1. The computer has run out of memory for the application.
Check the application documentation to determine the
memory requirements.
Memory modules may not have been installed correctly or
incorrect modules may have been used.
On system boards having integrated Intel video that use
1 MB of memory for video it is normal for POST to have
the memory count 1 MB short.
1. Too many Terminate and Stay Resident programs (TSRs)
are installed. Delete any unnecessary TSRs.
2. There is not enough memory for the application. Check
the memory requirements for the application or add
more memory.
Memory is not installed correctly and system is not booting.
Reinstall memory modules.
