I'm having an issue with my old PC shutting down unexpectedly when I'm playing games like Apex Legends. It started happening after about a week of use, and I never had any problems before. When it hangs, I hear a weird robotic sound similar to what's usual before a BSOD, but I don't actually see a blue screen. I can still move my mouse and switch between the programs I have open, but none of them work. Plus, my internet connection drops.
I've already swapped out a few parts, including the motherboard and power supply, but the issue continues. Here are my specs:
- Ryzen 5 2600x
- RX5500XT
- 16GB HyperX RAM DDR4
- Asus B450F Gaming
- Seasonic 620W PSU
- 3TB HDD
- 256GB SSD
Any ideas on what might be going wrong?

Issues like this can often be from unstable RAM. A faulty CPU is a possibility too, but it's less common. Given your setup, older RAM might be the culprit.
Have you tried unplugging and replugging the LMFB cord? That might help.
I did that already and made sure it's plugged in properly, but the problem is still there.
What power supply are you using? You left that out, and it's a crucial part of your build. It could be part of the problem.
Oops, forgot to mention! I'm using a Seasonic 620W Bronze right now, but I did have a Thermaltake 600W that I replaced it with.
You might want to set the RAM voltage a bit higher, like +0.25V. Sometimes RAM has issues under load and this can help stabilize it.
I'll give that a shot and see if it resolves the issue.

Yeah, I'm starting to think it could be the RAM. It's old, and I'm trying to rule everything out before I buy new parts.
