Welcome to the forums, newcomer!
For the sake of relevance, which CX unit do you have? The grey or the green labelled unit? As for the unit itself, how old is the unit in your build?
Might want to also add the specs to your build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
If you've added the RTX3060Ti as an upgrade, what GPU were you working with prior to said upgrade?
