I was in the middle of a gaming session when my PC suddenly froze, and the fans started making a loud noise. Since holding the power button didn't shut it down, I flipped the switch at the back of the unit. Now, it won't power back on and I have no idea what to do next. Any advice?

When you try to turn it on, does it show anything on the screen, or is it completely blank? If it's blank but it can access BIOS at times, your storage might be causing issues. If it’s totally dead, it could indeed be your PSU. Try pulling out your storage devices and see if it at least goes into BIOS. If not, then you’re likely looking at a PSU issue.
Try unplugging it from the wall and turn on the PSU, then hold the power button for a few seconds. After that, plug it back in and see if it powers on.
It sounds like your power supply unit (PSU) might have failed. Just out of curiosity, what graphics card are you using?
