Hello, I installed an AIO cooler for my Ryzen 5600x. The system refused to boot showing a RAM light(amber). My RAM has been in slot 2 and 4 positions without issue for about a year. So, after trying different combinations the RAM is now in slot 3 and 4 and working perfectly, and is the only combination it accepts now. I'm sure i didn't drop anything in slot 2 because the RAM stick still fits there but just won't boot. Does anyone know why the RAM now only works in slots 3 and 4?
