    DP55SB Built in March 2010, Was working, now giving random video and memory beep code errors


      System: DP55SB MB, i5-750 CPU, Corsair XMS3 TW3X4G1333C9A 4GB (2x2GB) RAM, Gigabyte GV-N94TOC-1GI graphics, Corsair VX550W PS.

      The system was working nicely until this Saturday (9/18/2010).  Then it started giving a 3-beep signal on boot.  Tested the system with memory from another operating Intel 5 series MB. Same result except that now I get intermittent blank screen and a 2-beep code on boot.  Tested with video card from the other 5 series MB, same result.  Called Intel support, tech had me disconnect everything but the PS and CPU and boot.  Got 3 beeps, so he said it was memory and hung up.  Only problem is that the memory and graphics card from this MB both work in the other Intel 5 series MB.  Suggestions?
