Question Is my CPU broken?

[FrannyPanny]

My PSU had a power surge or short-circuited because it fried my motherboard and PSU. I recently bought these parts and swapped out the defected ones for new ones but it doesn't boot. It turns on for half a second then turns off. The Mobo lights turn on and the orange LED turns on which means that all the parts are powered up. None of the critical part LEDs are on. I then swapped out the ram but it still doesn't work (tried other DIMM slots). My CPU and CPU socket has no broken pins and I trouble shooted HDD, GPU. I have no idea what's wrong with my PC. Any help would be appreciated. Thanks.

What is the power cord plugged into? Directly to the wall or to a power strip? Have you stuck a hair-dryer on the outlet to verify that it's not a power issue from a busted or burned out outlet? If it's plugged into a power strip, have you tried straight to the wall? Extension cord to a different outlet?

Currently is on a power strip but I have tried to plug it straight into a wall and it's the same outcome. Just tried using a hairdryer and it works fine.

I'll be sure to try everything.
I suspect the CPU because I bought a new motherboard, a new PSU, and new RAM and the PC still wouldn't boot. My old MOBO and PSU were dead and I needed new RAM because mine was getting outdated and dying. I took out the GPU and the problem still persisted and the only common denominator was the CPU.

So that's a good candidate too. But I do believe the motherboard should let the PSU stay 'up' if everything is out, but with all the troubleshooting LED's lit since it's empty.

What do you mean by letting the PSU stay 'up'?
