Question PC turns on for a brief moment and then immediatly turns off ?

[Pcbuildercoder]

Hey everyone,

I have a very weird issue. Every time I plug in my power cable, and power my PC on, I see the light of the GPU turning on briefly, and immediately turning off again. Then when I try it again it doesn't do it. Only when I pull out my power cable and put it back in and power it up, it does it again. What is my problem here guys?

Is this a new problem with a system that WAS working properly? OR, is this a brand new build?

Either your psu is dead or you have created a loop. Disconnect everything not needed from the PSU (fans hubs usb devices) and try again.

May I suggest you pop into your bios and lower your RAM speed to 3200 mhz.

Whenever you upgrade please check the speeds of RAM your CPU can support, not just your motherboard. Your chips max is 3200.
