It could be that all 4 sticks are bad, but you mentioned also that the second and fourth slot of your mobo display no information.
So it could be that your mobo is the culprit.
Do you have a other pc to test your RAM or could you use a friends pc to test your RAM.
Not readily available. I should clarify that when sticks of ram are in the even numbered slots, the pc will turn on, but my displays never come online. Waited upwards of 15 minutes one time, no luck.
Check the BIOS for correct clock timings and voltages, again if you've already done this before.
Please fill in your System Specs, especially the system board information. See here: System Specs - Fill in at Ten Forums
