I'm puzzled about what's going on with my computer. I assembled it and it functioned properly for a short time until suddenly the monitor stopped and all my programs ended as if Discord had cut off mid-sentence. My mouse, microphone, keyboard, and the entire PC remained powered on. I had to physically shut it down by pressing power repeatedly—it wasn't enough. I'm unsure what's causing this issue, as it seems to happen intermittently, sometimes more often. The BIOS is set to show only codes, displaying A0 constantly, which I noticed recently. I only modified the BIOS settings to show just codes and specify boot instructions; otherwise it uses default settings.
My system specs are: Intel Core i9-13900K, Asus ROG Maximus Z790 Hero ATX LGA 1700, Corsair Dominator Platinum 64GB (2x32GB DDR5 6000MHz CL30), Seagate Firecuda 530 4TB M.2-2280 PCIe 4.0, Seagate IronWolf Pro 4TB 3.5" 7200 RPM, Corsair iCUE H150i Elite LCD XT, NVIDIA 3090ti Founders Edition, and Corsair RM1000x. The monitor is a Samsung Odyssey G7 27".
I'm seeking guidance because I'm completely confused and my troubleshooting hasn't helped. Please let me know if you need more details to assist. I'm not an expert, but I'll do my best.

It's completely new. I spent a lot of time adjusting it and came to one clear thought: my GPU was failing. It would shut down during problems, especially when under stress, even when I wasn't using any apps—sometimes just being on the desktop without a window open. Since then, I've upgraded to a different machine with the 2070 Super, which has worked perfectly. I also noticed the 3090 Ti needed three power cables, while the 2070 only required two. To rule out a power supply or cable issue, I tested it with two and three cables, and after flipping one, it still functioned. So I believe all three cables can support the GPU, and everything is working fine now.
The 2070S isn't similar to a 3090Ti at all. Testing every cable with the 2070S probably won't help much for troubleshooting. That PSU might be faulty when under heavy load (like running the 3090Ti). It's uncertain, but it could be either the 3090Ti or the PSU itself. Unless you can rule out one of them by using a more robust system or getting a replacement from online stores, it seems the 3090Ti might be the issue.
