I have built many PCs and have never had a problem until now.
I have the Intel DP43BF motherboard; an intel core 2 duo E7500 processor (BX80571E7500), and am using Crucial RAM DDR3,1333mhz (CT2KIT25664BA1339)
When I start the computer I get 3 beeps; which, according to intel, suggests a memory issue. I have now tried 4 seperate DIMMS (one by one) and none of them have worked, so I concluded it was the board. I replaced the board and am having the exact same problem. I have taken the board out the case to make sure it is not shorting/grounded- it is not. I used the Crucial memory finder to make sure that this memory matched this board- and it does.
I am going insane!!! any help would GREATLY be appreciated!! I have asked tons of people and no one can figure this out!
