Hello Sedlis, first of all, I would need to let you know that this motherboard has been out of support since December 2008. http://www.intel.com/support/motherboards/desktop/sb/CS-028521.htm
However, since the motherboard is running the latest BIOS available for it, my recommendations for this kind of memory problem are the following:
- Test the system out of the chassis, minimal configuration please. (Motherboard, processor, power supply and video card) No memory.
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.

- - Include 1 memory stick on DIMM #1 and restart the system.
When did this behavior started? Any recent change you made on the system?
