No video output when using the first 2 ram slots

[Shattered Dreams]

Hello,

Yesterday I installed my new PC. (specs below)
As a first timer, I put my 2 (8GB) RAM sticks in the 2 first slots closest to the CPU.
When booting the PC, I received no video output, my screen remained black.

I changed up the position of the RAM sticks, which was a succes.
Great right? Well no, the only way to get video output is by putting the RAM in slots DIMMB1 and/or DIMMB2.

Link to the manual's ram page: http://
(The image function seems to do nothing, so I will post the screenshots as a hyperlink)

So basicly, whenever I place a RAM stick into the DIMMA1 or DIMMA2 slot, I do not receive video output whatsoever.
The ideal situation is putting my 2 RAM into slots DIMMA2 and DIMMB2 (slot 2 and 4)

Below is a list of the RAM placements I have tried:

Spoiler

1. = DIMMA1 / 2. = DIMMA2 / 3. = DIMMB1 / 4. = DIMMB2

1. 2. 3. 4.
0 0 1 1 = success
0 0 0 1 = success
0 0 1 0 = success
1 1 0 0 = fail
1 0 0 0 = fail
0 1 0 0 = fail
1 0 1 0 = fail
0 1 0 1 = fail

I guess it is safe to say my problem only occurs whenever I put one of the sticks into slot 1 or 2.

Does anybody have an idea why my first 2 slots cause me to get no video ouput?

Thanks in advance!

Hi, It might be a bent pin in the CPU socket.
