So i was cleaning my PSU, had to remove the RAMs to remove it (really tight cage).
I put them back together and it doesn't post (no beeps).
I remove one module and it works. I try it again with the other one and it still works.
Curiously after using just the other slot in my motherboard it still works!
What went wrong? Also i tried swapping the order. Still nothing.
