I've been having issues with my PC crashing whenever I put it under load, like when I try to play games such as Cyberpunk, Minecraft, or Arc Raiders. I recently upgraded my setup with a Ryzen 7 5800X CPU, an RX 9060 XT 16GB GPU, and a B550 Eagle motherboard, and I have 16GB of single-channel DDR4 RAM running at 2933 MHz. I also have a Corsair 850E PSU and a 1TB Kingston SSD. I've made sure all my drivers and Windows updates are current, and even rolled back to an earlier version of Windows, but the crashes persist. Stress testing with 3DMark yielded a decent score of 12,500, which makes me think my hardware is fine. I've experimented with overclocking as well and tried running games on different monitor resolutions (3440 x 1440 and 1920 x 1080). I'm just not sure what I might be missing—any advice would be greatly appreciated!

I had similar issues after switching parts. One thing I'd suggest is doing a clean install of Windows, especially if you're using the SSD from your old setup. Sometimes leftover settings from the previous hardware can cause glitches. Also, verify that your temperatures are normal during stress tests. For stress testing the CPU, you might also want to try Cinebench to get a better idea of its performance.
It sounds like you might be dealing with a stability issue rather than a lack of performance, considering your specs. Have you tried using two sticks of RAM instead of one? Single-channel can sometimes lead to crashes on Ryzen systems. Also, make sure you've completely uninstalled any old GPU drivers with a tool like DDU before reinstalling the latest ones. Keeping an eye on your CPU and GPU temperatures during load is also crucial; they could still be overheating. If you're still having issues, run a memory test like MemTest86 to rule out RAM problems.
