I accidentally unplugged my PC while I was trying to unplug my laptop, and now my PC seems completely dead. After I unplugged it, my mouse was lit up for about 10 seconds, but when I plugged it back in (while it was still in sleep mode), I went out. Now that I'm back and trying to power it on, there's no sign of life—no lights, no fan activity, nothing at all. I've checked the plug and the cable, and they seem to be working fine since I can hear a buzzing sound when plugging it in. My specs are:
- PSU: Corsair CV650
- Motherboard: MSI Mortar (specific model number escapes me)
I've already tried unplugging everything, powering off, and holding down the power button for 30 seconds, but nothing seems to work. I'm open to suggestions!

If your PC is about 5 years old, it could be a power supply issue. Even though it buzzes, it doesn't always mean it's functioning perfectly. You might want to test it with another PSU if you have one available. Also, consider checking if any visible damage or burn marks on the motherboard could indicate a problem.
First things first, have you checked if the power supply switch on the back is turned on? It can easily get switched off accidentally. If that’s fine, make sure all the internal cables are securely connected, especially the one from the PSU to the motherboard. Sometimes a loose connection can cause this issue. Good luck!
