You have bad RAM, as suspected. If it's still under warranty then contact PCS to get BOTH RAM sticks RMA'd. DO NOT just replace one stick, demand a pair of matched sticks.
Notwithstanding the comments from @SpyderTracks, who absolutely knows what he's talking about when it comes to hardware, you probably want to try and stop the BSODs. The dumps strongly suggest that bad RAM may be the cause of these BSODs. Since you have two sticks of 16GB Corsair...
Based on all those dumps, some of which fail with different bugcheck codes, I still think that bad RAM is the most likelyu cause here. You need to test your RAM...

I agree totally with the opinions above, Windows Defender and Windows Firewall are all you need.
Based on those dumps, some of which fail with different bugcheck codes, I still think that bad RAM is by far the most likely cause here. You should test your RAM (at 4800MHz)...

I'm watching the Guy Martin in China programme. He's just said that it's cheaper to ship Scottish cod to China to be filleted and then ship it back to be sold in Scottish supermarkets, than it is to fillet it in Scotland.
How mad is that?
That download advice should have been superseeded....
Can you please download the SysnativeBSODCollectionApp and save it to the Desktop. Then run it and upload the resulting zip file to a cloud service with a link to it here. The SysnativeBSODCollectionApp collects all the troubleshooting data...
If the PSU has been working hard for 4 years it's entirely possible that it' struggling now, especially since you've made it work even harder with that new GPU. I would plan to replace that PSU in the near future.
OK, that's important information. Thank you
If you can only run in Safe Mode...
I did wonder about that PSU, particularly as all the dumps, including the latest, fail in ACPI. How old is this system? If @SpyderTracks thinks that your PSU may be on the small side it's probably been working at near its peak power since you had the PC, that may cause it to start to become...
I'm puzzled then why those devices are missing drivers? PCS wouldn't have shipped it like that. The problem for me with those missing drivers is that it calls into question the stability of your Windows system.
Do please run the Sysnative data collector app again and upload the new output...
Have you reinstalled Windows since you took delivery of this PC? I ask because there are several devices missing drivers...

All of those dumps are pretty near identical and all are 0x7E bugchecks (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) which is a really common bugcheck. However, they all fail with a 0xC0000005 exception code, indicating an invalid memory reference. That always makes me look at RAM before looking...
Can you still boot the Windows installation media?
Is that installation system stable?
Run Startup Repair from the installation system. Does that work? If not then I'd suspect your NVMe system drive is flaky.
