I was watching YouTube when my PC just turned off randomly, and now it won't turn back on. I've tried unplugging it and plugging it back in several times, but nothing seems to work. A few weeks ago, I had to unplug and replug it just to get it started. I've also removed the RAM and tested one stick at a time, plus I took out and reinserted the CMOS battery, but I'm still stuck. Any advice would be appreciated! (My PC is an Omen 40L GT21-1304.)

Definitely start by checking the power supply. You can unplug it and try shorting the start pins to see if it powers on. If it does, check the voltages to ensure everything's working.
Make sure to check the power supply and also look for any potential BIOS issues. That’s another common problem. Just be cautious when examining the BIOS.
I'm leaning towards a dead PSU here. Hopefully, it didn't cause any damage to your other components when it went out.
It sounds like your power supply unit (PSU) could be failing. You might want to check if the motherboard is properly grounded in the case or if something is causing a short circuit where it's mounted.
Follow up on the power supply issue. If you disconnect it and short the start pins, it should help diagnose if it’s dead. Just remember to test the voltages afterward.
