Hello, I want to start by saying that I’m not very familiar with technology, so explaining this will be quite simple.
A few months back, my computer began having serious problems shutting down. It was functioning normally most of the time until I played Baldur's Gate 3 and encountered the first major crash. Both screens would turn black, a "no signal/input" warning would appear, and I could only force shut it down by pressing a button and then restarting. In some instances, while on Discord chatting with friends, my screens would go dark for about 6 to 7 seconds before the system cut off as well.
At first, this only happened when playing BG3; I tried to avoid it but after a few weeks it started affecting other games too. After upgrading my graphics card, the issue stopped for a while, but it returned recently while I was playing FFXIV—a game that’s less demanding than BG3 and runs smoothly.
Initially, I replaced almost every part of my PC except the motherboard, CPU, and SSDs. Yesterday, I bought a new motherboard and CPU, installed them in the hope things would improve, but the problem kept coming back about a week ago.
I’m wondering if maybe my power supply unit (PSU) isn’t providing enough power to start up the PC, which I checked online using several calculators and got mixed results (as I’m not very tech-savvy, that’s all I could do). Would anyone please look at my current specs and see if my PSU could be the cause?
Here are my current specifications:
PC specs:
Motherboard: Asus ROG strix b550 f gaming
CPU: Ryzen 9 5950X 3.4ghz
GPU: Gigabyte GeForce RTX 3090
RAM: 2x 32GB DDR4
PSU: Corsair HX750 80plus plat
Cooling: NZXT Kraken elite 360
Previous PC specs:
Motherboard: AORUS elite B550 v2
CPU: Ryzen 5 5600x
GPU: GeForce RTX 3070
RAM: 2x 32GB DDR4
PSU: Kolink Modular Power 850W 80 Plus Bronze
Please help me out—I’m really worried.

Did you reinstall the operating system after swapping the motherboards? Please share the link to the RAM kit used for your setup. Regarding your RTX3090, it should have been matched with a 1.2KW power supply. What is the current BIOS version of your motherboard?

I didn't perform a fresh setup after the swap, just a clean reinstall three days ago and changed the motherboards last night.
Here are the RAM sticks I'm using:
https://www.amazon.com/Kingston-FURY-320...PXJCB?th=1
I'm not completely certain about the BIOS, but after searching how to locate it, my system details show "American Megatrends Inc. 2407 12/07/2022".
