Question New build won’t POST ?

[KennyLee86]

Building a new computer
Flicks on then off, repeatedly. After I turn off the computer, RGB ram sticks light up.
rough build, can give exact components if need be.
i9
Msi-790 motherboard
Rtx 4090
Couple nvme sticks
Enermax liqmax 3 cpu cooler (just using cooler hooked up to pump pins on motherboard directly)
Using system fans not fans with Enermax. Forgot to hook up led of Enermax)
1250 watt psu segotep

No CPU?

No CPU?

It’s installed, but wondering if it has to do to the ENERMAX not having the led properly connected? Maybe motherboard shuts down because it doesn’t read a cpu fan properly?

Last time I experienced that issue it ended up being bent pins on MOBO unfortunately. If it was not reading CPU fan or more so not detecting or throwing error it would most likely still post but give you a notice to either ignore in BIOS or connect to the proper fan header.

What pins were bent? The ones under the cpu?

So I pulled it all out, used one ram stick one cpu old fan, and old power supply. Then power supply stayed on, fan stayed on, and one ram stick stayed lit up. Removed all storage disks. So it works with minimal connections

Yes pins in the socket.

 

[Blutdog]

Did you narrow down what the culprit was? Or at the least what it wasn't?

I would proceed to do a bios update, now that you have managed to get to this point.
