Power button does nothing/PC won't jumpstart

[etherealcross]

So last afternoon, my PC is working fine. I then received 2 fans and a tower cooler. So I unplugged my PC, and then I unplugged the Intel (LGA 1700) CPU cooler. Since it's pretty hard to mount the tower cooler, I also unplugged my GPU and nvme to PCIe card. After the cooler is assembled, plugged on both 4 pin dan and argb port, I proceed to install the fan. The fan seems like able to be daisy chained, like each fan has male and female argb, and male and female 4pin fan. So I chain them, put them on front, and do some cable management to plug it on the appropriate port. Since screwing from angle is pretty hard, so I unplug the USB 3.0 header and 12atx cable, and plug them back after done with the fan stuff. After I plugged everything, GPU, PCIe cards and all, I plug my peripheral (mouse, keyboard, USB wifi) and plugged the PSU cable). I flipped the PSU switch and I press the power button. But then I'm surprised when it doesn't do anything, no lights, no sounds, nothing. I tried unplugging and plugging the PSU cable, doesn't work. I get rid of all front panel header and jumpstart it with a screwdriver, doesn't work. I get rid of every casing fan headers, still no response. My motherboard is MSI mag b660m mortar, so it has lights when there's a problem somewhere (CPU, GPU, ram, etc) but no lights at all. I tried reseating the 12atx cable several times, yet nothing changed

Build the system outside the case while using just the minimum required parts to boot and retry.

I did using only the CPU cooler (tower), 1 stick of ram, and then plugging the 24pin atx and 8pin CPU. Still no response when I jumpstart it with the power button or with screwdriver. As if it doesn't receive electricity.

Ok, take the cooler off and check the CPU and the socket.

 

Disconnect the PSU from everything and use the paperclip method to check if it powers on.

Paperclip test done, PSU is alive. Cpu also fine, I haven't unplugged the CPU during the cooler replacement process earlier.

remove the CR2032 battery and leave the board alone for 15 minutes. Then install the CMOS battery and try to turn it on in the minimum configuration.

Did it. Still no response from the motherboard/fan/psu.

I know you did not remove the CPU but you did two things:

- installed the cooler holding mechanism (bracket)

- changed the mounting pressure on the CPU (exerted by the cooler)

And that can affect the CPU socket and the contact.

Okay, now that I released all the brackets, lifted and checked the CPU, the bottom surface is normal, the pins is also normal. I put it back, plugged the box CPU fan to the header (without putting it above the CPU), and again, jumpstarting the PC. And still, nothing happened. Fan not spinning, lights not blinking.

Remove the NVME, use the other RAM stick, disconnect all fans and RGB, disconnect the cooler mounting hardware, place a cooler on top of the CPU, remove the GPU and try booting by shorting the pins on the header.

Check all power connections are plugged in correctly. All the way in. sometimes it's possible to think that connections/plugs are fitted but they can be only half inserted. id look straight for the 24 pin.

 

Another thing to look for see if you can hear any slight sound coming from the psu it's self after pressed the on button or by jumping it.

I did remove the 2nd nvme, changed the position of the ram stick (I only have 1), disconnected the mounting hardware, placed the cooler, shorted the pin, still nothing happened. I re check many times that the cables, both CPU 8pin and 24pin atx are fully inserted.

And no, there's no sound from the PSU whatsoever.

But we know the PSU at least turns on when there's no load. That indicates that something is shorting the PSU and causes the system not to turn on when you button it.

 

Are you using any cable extensions, custom cables, or riser cables?

No, the PSU is non modular, cooler master 500w. I'm not using any custom cables or riser.

This might be a long shot, but it might work...

Disconnect everything from the PSU. Connect just the GPU to the PSU and try powering the PSU with the paperclip method.

Repeat for just the motherboard. And so on.

If the PSU won't start with, for example, the motherboard, then try with a different PSU.
