Question Built PC for Christmas but won't power on correctly

[Digedog123]

Hey guys,

As the title states I bought a bunch of parts from scorptec so I could build a PC for my brother for Christmas. I used two old parts, a GPU and CPU that I had in my old computer (a gtx 1070 and i7 7700k). Completely fine parts for a first gaming PC if you ask me 😅.

So I bought the rest required parts to build a PC and after building, I go to turn it on and something extremely odd happens. I press the power button and it goes blue for about a second (the LED behind the power button), the fans inside the spinup for a second and then, nothing. No power or something. I can reproduce this exact scenario everytime I turn it on. So my first thought is to unplug cords and replug them back in, didn't work. Tried holding down the power button, nope. Switched power cords and same issue. Then after some troubleshooting by myself I assumed the new PSU I bought (Corsair cx650) is faulty so I unplugged the main power adaptor to the motherboard and the CPU cord, and tried using my current PC's PSU a RX 750 and had the same issue.

Here I am, not really having a clue what else could be wrong except a faulty motherboard?

I can provide exact parts list and more detailed description of what I've done so far for troubleshooting if necessary.

Check the RAM. Also how did you go about checking to see if all the parts in the build are compatible.

I also did check the RAM, and swapped the locations from 1-3 to 2-4 and didn't change anything. In terms of compatibility, I scimmed over the motherboard with the RAM and what types of CPU it sockets. But I just double checked the compatibility list on the ASROCK website and my CPU isn't listed // uh oh I guess I went big dumb ahaha

yeah, the 3xx series motherboard need the 8th and 9th gen CPU's
