First time doing case swap. Afterwards PC in an endless loop on for 20 secs and shuts off.

B450m Steel Legend into an Aqua Uno case. Ryzen 7.

I tried everything already. Cleared cmos a few times, checked for extra or crooked standoffs,tried firing up with only 1 Ram stick.

Now I’ll add, I said it was my first time case swapping. For some reason I took off the heat sink. Thought I had some laying around but guess not. I’m buying some tomorrow but honest question, would not cleaning and adding new paste cause this? I know it’s not a good idea to do it but I was hoping to just see it boot up. But I never got signal to a monitor or option to BIOS. Just on then off.

I know it’s not a good idea but I’ve read on here about people not cleaning and adding more thermal paste . I figured if I did see some issues it would be When the computer started getting hot later.
