Problem with brand new build.

[Mrbenw]

Hi guys I went agianst my better judgement and went ahead with buying parts and trying to build my own PC. I knew something was bound to go ****-up and I already have a problem I am hoping someone may be able to help with.

I finished my build this morning, followed a few guides and such. Everything went (seemingly) smoothly so I didn't encounter any problems along the way that I can refer back to...

I turn the system on and I only get a very brief moment of power before everything goes off. The lights all come on and the case fan spins but it lasts no longer than it takes to blink. I have checked everything is connected properly and everything seems fine.

The only thought I had was I noticed in my small bag of case accessories (screws etc) there were some very small circular things that can only be described as washers or something. I'm thinking maybe I need those somehow on the motherboard screws or the case screws that the mobo sits on. Maybe they stop 2 metals from touching that cause it to short out?

Any help would be hugely appreciated!

Yes I plugged in the cables between PSU and mobo. I'll give it the old 'unplug and plug back in' trick to see if they were not in properly, but they seem okay.

Many thanks for the prompt help guys.

I made sure the 2 PSU connectors were in the mobo correctly and they were.

Also I can note that the case fan spins within the brief moment, as does the CPU fan, and even when it's turned straight back off the little lights within the GRX card remain on.

I'll try just booting with the mobo, with some ram out now.

I solved it. It was a very, very simple mistake of not connecting the 2nd motherboard 4pin cable from the psu, I had only connected the larger one. I get wound up too easily and start panicking but without the feedback here I could have fretted all day.

Thanks for the feedback and to whom mentioned to check this. On with the build!
