My pc doesnt power on anymore for no reason

[Jud!]

My so I have a Ryzen 3700x Msi  X570 Gaming edge WIFI motherboard and a Rtx 2070 super for my gpu. i also have an EVGA 850 watt psu. I ordered a new case cause my other one was quite old. It gets here and I replace the case and install everything the same and it doesnt power on. I swapped the psu out for a 650 watt corsair one that for sure works and it still didnt power on. I bought a new motherboard and it still gives me nothing. the fans dont even ramp up. I also changed the ram. Could it be the cpu?

Yup. You may have damaged it with ESD during the transition to the new case.

I have built hundreds of computer never wore any gloves or anti static bracelets... 

 

Was I just lucky ?

 

The only thing I do is work on appropriate surface and wear non-wool clothes. Also I touch the case for couple seconds to get rid of static electricity before building the pc.

Are you sure you plugged in the front panel connectors properly? Mistakes like plugging the power button into the reset header is pretty common.

so it would be the cpu then? cause i mean i didnt take it out of the socket until i changed the motherboard today

Yep I verified it with the MB handbook too. I also tried just shorting it with a screwdriver.

Well, here are the standard troubleshooting steps for this sort of thing. Make sure you check these all off.

The machine doesn't do anything. No beeps, LEDs or spinning fans.

1. Check if your power cable is firmly plugged in on both ends (you would be surprised how many issues this resolves)
2. Check if the power supply (PSU) has a button to cut the power to the machine. Check if this button is in the position denoted with ON or I
3. Check if EVERY power cable is plugged in securely, reseat if necessary.
4. Check if the power button is installed correctly (consult your motherboard manual)
5. Try shorting out the pins you connect the power button to manually. If this powers on your system, you have a faulty power button.
6. Check with a device of which you know that it works if the power outlet you're using is actually providing power.

After that, you either have a dead CPU, or your new motherboard is DOA(which does happen, and you could just be that unlucky).

Even if you have a bad CPU or RAM, the board should still power on and you'll just get a beep code or a POST code via the board LCD display. I suspect there's something going on with power delivery or the actual outlet you're using. It's very odd that you're not getting any sign of life with two different motherboards and two different PSUs. That just seems very implausible to me that all 4 components are dead (that being said, it's very possible a bad outlet could kill everything). Try moving the system to another outlet in the room that's hopefully on a different breaker.

I have my old system that ive tried everything on along with the gpu psu that is on a different breaker. i also took that system and plugged it into the same cable i have for my new system and it worked. so my old system works with my psu

Alright so an update. Im just really dumb and had the power switch plugged into the wrong pins on the MB. I realized this yesterday even tho i had looked through the manual so many times. So thanks for your guys help anyways.
