Strange boot behaviour in new build

Bootlooper4Lyf · January 1, 2021

Hi guys, A few days ago I spent the afternoon helping my brother to build his new PC. I’ve done a few builds before so somewhat arrogantly put everything into the case and when I tried to boot, the pc fans would spin for 2 seconds, a light labeled CPU on the motherboard would briefly light up and the motherboard RGB lights would also light up, and then they just die, the pc would then spin again for 2 seconds and die again. It would repeat this until I turned the power supply off.

I ended up taking everything out of the system to breadboard the system, until I was just launching the motherboard, CPU and ram attached to the power supply out of the case. The PC still does this restart loop with a different power supply, RAM in different slots and no ram at all and with another CPU cooler. I also took a look at the pins and they all looked fine, however I will attach a picture just incase I have missed something (https://imgur.com/a/liIOBmc).

Here is a video of the issue (https://youtu.be/xJf5KFgTBPs) while the computer is in the case. As mentioned this persists when i'm breadboarding with just the motherboard, CPU and power supply connected and still happens with a confirmed working power supply.

Is it safe to say at this point that the motherboard is just faulty and I should just get an RMA? I’ve never had an issue with a build so I’m not sure whats going on. Thanks for the help!

Here is the link to the parts list, for some reason it won't format correctly so apologies for the link! https://pcpartpicker.com/list/7m6JBc

edit: I have also tried clearing the CMOS as well as just leaving the computer to do this loop for 5 minutes, and in both cases the computer just continued to loop.

Have you try only 1 stick of ram?

Also I would try a different kit ram before ruling out the motherboard.

Yeah I've tried only 1 stick of ram and no ram at all and the behaviour didn't change unfortunately.

To anyone who finds this thread at a later date. I decided that it was the Motherboard which was causing the issues and got an RMA, new motherboard works perfectly and the computer is running fine now.
