I've been having an issue with my PC where it restarts itself while I'm gaming. Last night, I played CS for a while without problems, but today, while surfing the web and playing Hollow Knight, my PC restarted after about 10-15 minutes. I turned it back on, but it restarted again while playing CS, and this time, it got stuck in a restart loop. I haven't powered it back on since that incident. I'm wondering what could be causing this and what I should check to diagnose the problem. Here are my specs: i5 10th gen, MSI B560M Pro-E, 16 GB RAM, GTX 980 Ti, Corsair 550W PSU.

It sounds like you might have an issue with your power supply (PSU). When gaming, it can trip a safety feature if it's failing, which causes the restart. I'd suggest checking the age of your PSU and if you can, try borrowing a good one to test it in your system. That's often a common culprit in situations like this.
I agree, your PSU could be the main problem here. It might be going into defense mode if it's struggling. Your specs look fine for gaming, but maybe verify them against the minimum requirements for the games you're playing. Also, if your PSU is old, that could definitely explain the issue.
If you're still having problems, make sure to check the voltage output of your power socket. I had a case where my socket was providing inconsistent voltage, which led to restarts in my rig. Just some things to keep in mind while troubleshooting!
You could also try changing the power socket for your PC. Sometimes the socket itself can cause issues like this. I had a similar problem and swapping the socket fixed it for me. Also, remember to check your CPU and GPU temperatures while gaming; overheating can cause shutdowns as well.
