Solved

Computer turns on for 1 second, then back off. Tried everything.

I've been having some issues with my PC since a power outage we had recently.

Here's my specs:
CPU: Intel i5 3570k
MOBO: ASRock Z77 Extreme4 LGA 1155 Intel Z77
RAM: Kingston HyperX 1600 4gb stick
PSU: Antec EarthWatts 650W
GPU: ASUS GTX760-DC2OC-2GD5 GeForce GTX 760 2GB 256-Bit GDDR5
CASE: Corsair Vengeance Series C70

When I go to boot up my PC, it shows power, then turns right back off. No beeps, nothing.

The fans and lights all work, the Mobo is brand new, the RAM is the one stick of two that works after the power outage. The PSU works 100% (tested in other PC).

I've tried bypassing the case's power switch, clearing CMOS, nothing. The only thing I can think of is the CPU.

When testing it a while back, shortly after the surge initially happened, I got the PC to start in a different mobo, and it seemed to be fine, but I could smell something burning. I turned it off, thinking nothing of it, and now it won't work. (The mobo has since been replaced due to bent CPU pins.)

If ANYONE could help me find a solution, I would be most grateful!

    It is PSU or CPU. Jump the PSU by removing the ATX 24( or 20+4) pin, and connect the green wire to a black wire with a paper clip. If the fans start up, then your CPU is dead.
