HELP: 2 RAM Slots Stopped Working on H97

[Viruzz]

Hi,
Something strange happened today, i replaced my heat sink (cleaned the thermal paste before that of course), thats it, didnt do anything else.

So i turn on my PC and have these fast Beep...Beep...Beep
The first thing i checked is RAM, so I removed all my RAM and turned on my PC and got the same beep, so it means that this particular Beep says that I have no RAM or there is some sort of RAM issue.

The RAM slots : 4-2-3-1.
For dual channel it supposed to go into 1 and 2 BUT if I put anything into RAM slot 1 (or 3) (any first 2 slots on the right side) i get these beeps.
right now my PC works with RAM in slots 4 and 2, I know its not dual channel but it works.

Any idea why and how slots 1 and 3 stopped working?

Mobo: Gigabyte GA-H97-GAMING 3
RAM: Corsair Vengeance Pro 2x8GB

Thanks

Take your heat sink off again take your cpu out of the socket you may have put to much pressure on your cpu socket with screwing in the heat sink to hard bending the pins to far.

Take the cpu out of its socket take a look at the pins.

Reseat your CPU put heat sink on with less pressure on the screws and test again.

Thanks BUT, I had Coolermaster 220 EVO before and I replaced it with Stock Intel cooler that as you know has plastic pins.
Anyway, I will do as you say just in case, also maybe some thermal paste spilled underside.
