It is most likely due to a mismatch of memory sticks. Most motherboards 
seem to have particular requirements about filling the memory slots with 
  memory. And you must have a 'balanced' setup with matched amounts in 
the lower numbered slots.

DDR2 is even worse. I don't think you can do DDR2 with an odd number of 
memory sticks. Which leads to the question of how did you get 7Gig of 
RAM. I didn't think that 4Gig ram modules were available yet, which 
imply you have 3 times 2G plus 1G in modules. And the MB does not like 
the fact that you have 2G in slot 3 and 1G in slot 4.

Try with 6G (3x2) and 5 (2x2+1)...5G *may* work since there would be 
nothing in slot 4 to cause a problem.
