PC powers on for a second, then goes off

[Skeej]

Hi guys so basically my pc that I just built won't turn on. When I press the power button the motherboard flashes red, one of the case fans slightly moves and the gpu flashes blue but then it just powers off completely. Any help? I attached a picture and I know my cables are a mess I just wanted to see that it worked before I managed them

Need to start with the basics. Take the card out and try it. Just to see if it stays on. Move the ram over to the next slot closest to the cpu. Check the power connections on both ends. Re seat the cpu.

Sounds like a short. This is a pain to do, but I'd take everything out of the case, set on a phonebook (for easier access) and try to turn it on.

If it doesn, you have a short in your case.

The CMOS battery could be empty (unlikely, since this is a new build).

I have tried the ram in all the spots, checked power connections but I can't take out the you because the processor doesn't have integrated graphics it's an i5 9400f

Try reseating it, maybe there is no connection.

You will at least see, if it boots without GPU. Just without picture.

Did you take the whole system out of the case before you did that?

No, what would that do though?

If you have a short between the mobo/cards, and the case, what you are seeing would happen.

By taking everything out of the case, and placing on a phonebook, you can eliminate the case being the source of the short.

Okay will do, I'll let you know what happens

Okay I solved it. Turns out I had a fan plugged into the motherboard and psu at the same time which was causing a short. My bad for being dumb and thanks everyone
