Question PC POSTING ERRORS

[NTfarm]

I recently got an rtx 3060 to put in my pc. Putting it in results in the pc fan spinning then stopping immediately. But the pc boots up as normal when the gpu is not installed, it also boots when I don’t have it plugged in to the pc but connected via the pcie cord.
My pc specs are:
Ryzen 5 2600
B450M gaming
16gig of ram
Thermaltake TR2 550w

Please help as I don’t want $2000 to go down the drain.
