I experienced a power outage while using my desktop PC, which is connected to a surge protector. After the power cut, the PC won't boot up at all. I've already tried holding the power button while unplugged and plugging it back in, and I've also jumped the clear CMOS, but nothing seems to work. What are the steps I can take to figure out what's wrong?

This might sound silly, but have you checked if there's a reset switch or breaker on your surge protector? Also, try plugging something else into the same outlet to see if it works. It could be the surge protector itself that's not functioning after the power cut.
I had a similar experience when a brownout damaged a hard drive on my computer a while back. It was a pain, but I managed to figure out that the hard drive was the culprit. I suggest you check if the computer turns on at all—if it does, maybe try booting from a Linux Live USB or check if the BIOS recognizes the hard drive. You could also try swapping it out for a different one to see if that helps. If the PC is completely dead, then definitely try a different power supply and make sure it’s plugged into a working outlet, not just another surge protector.
It sounds like your PC might have been fried by the power outage. Surge protectors often don't safeguard against the brownouts that happen when power goes out or the little surges when power comes back on. It's really a good idea to use a UPS for better protection. I’d suggest unplugging your power supply and holding the power button for about 15 seconds to drain any residual power. Let it sit overnight; sometimes, the power supply can get 'stuck.' After that, try removing all unnecessary components like extra cards and USB devices to narrow down the issue.
Sometimes, you just need to reset the surge protector! Look for a button—some models have them near the wall outlet rather than on the power strip itself. It could be as simple as that to get things running again!
Make sure you're clear on whether the PC isn't turning on at all or it's just not booting up. If it doesn't turn on, definitely try using a different power supply. If it does turn on but won't boot, see if you can access BIOS and check if your hard drive is detected.
