Look in Reliability History and Event Viewer for any entries that are captured just before or at the time of the restarts.

Check all external power connections from outlet to pc to ensure that none are loose and wiggly.

Swap in another known working power cable to the PSU.

Power down, unplug, open the case.

Verify by sight and feel that all cards, connectors, RAM, and jumpers are fully and firmly in place.

No pinched or kinked wires.

Motherboard BIOS fully up to date?

What is the exact modelnumber of the RAM?
One kit of 4 dimms or 2 kits of 2 dimms?

Yes, i flash bios update my motherboard before installed RAM and CPU.
This is modem number of rams: CMH16GX4M2Z3200C16
i don't know what you mean about 2 dimm or 4 dimm but, (im not that good at pc parts) I bought 2 pack, each pack have 2 ram so total 4 ram.

I bought 2 pack, each pack have 2 ram so total 4 ram.

OK. The RAM is Ryzen Optimized so that's good. Now check if the versions are the same. The version number (like 4.31) you'll find on the sticks, it's written next or under the voltage.
