Question Help! PC boots, no display, power button won't work to turn off

[ccaracal]

Really at my wit’s end with this thing.

Transported my PC to my new living situation, was working fine before I shut it off and unplugged it, didn’t have a bumpy ride and I transported it on its side. The problems started when I tried to set it up at the new place. Everything internally was on, the fans, the lights, etc. but my monitor wasn’t displaying anything whatsoever, it stayed in sleep mode. I tried turning my PC off but the power button didn’t do anything, no matter how long I held it. When I switch off the psu and turn it back on, I can use the power button to turn the pc on but not to turn it off. My CPU error light was on on the motherboard, so I replaced it. Light was still on so I was told it was a motherboard issue and replaced that too.

so far I have replaced the CPU and mobo, I have a 2 month old gpu that hasn’t given me any grief. I’ve tried resetting cmos, tried different RAM, basically everything. I’m at a loss. Any advice? I’m not much of a computer person so dumbing it down would be appreciated.

my specs:
mobo - B550 elite AX V2
CPU - ryzen 5 5600
GPU - rtx 3060
psu - evga 650 g3
can provide more information if needed. Thanks guys.

Had a similar problem. Sold my old pc when I upgraded and when the guy took it home it wouldn't boot.
He brought it back and I gave him the money back.
I reseated CPU and blew the sockets of ram/gpu and it worked again.
Even tho I don't believe on my side cpu reseat did anything it might do for you. After I blew the dust off the gpu socket it worked.

I just had this problem and fixed it. I didn't have the RAM in all the way. I thought it was supposed to click by itself but I had to manually click it now it works.
