Hello!

PC powered off suddenly last night and would not power on back on. Pressing the power button does nothing, no beeps, fans or anything. Motherboard standby light was not lit, went to the store and bought a new PSU. Once that was installed, green light is now lit on the motherboard but still won't boot. It's an old Intel BOXDH77KC LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX. I tried doing a boot using a screwdriver and touching the connectors, but it didn't work, unless I'm doing it wrong which is possible, tried watching a video on it to make sure I was doing it right. Nothing happens.

There was a storm last night so it's a possibility more than just the PSU went out. My CPU is also just as old as the motherboard so I'm wondering if it's just time to replace them both, but I'd like to see if there's a way to test what is causing the problem without spending money on both a motherboard and CPU.

Other troubleshooting steps I tried:

Unplugging everything, plugging one thing in at a time and trying to turn it on.
Reseated the GPU as well (GTX 970 if it matters for troubleshooting).
Reseated RAM.

I'm kind of at a loss right now and appreciate any guidance. Thank you!
