Motherboard issue?

post #1 of 19

Thread Starter 
So I have spent the last day and a half redoing my watercooling loop in my computer as well as sleeving wires.

After leak testing all night and today with the paperclip in the PSU trick, I connected all of the cables to the mobo and tried to boot up. I got nothing.

It seems that the PSU is not recognizing that the motherboard is connected because nothing starts up at all, fan controller, water loop, HDDs...nada.

What could have caused this and is there a way of fixing it? I have not touched the mobo at all and the only things I changed have nothing to do with the mobo.

this may sound weird but take everything out of the case and put it all back in.

I say this because it might eleviate a grounding issue that might be going on that can only be fixed with a reseat.

That would have been my next suggestion.
Take the guts out of the case and try booting with boot drive, vc, and one stick of ram for starters.

Make sure that 24 pin is well seated man. I had that issue that nothing went went up.. I pused the 24 some more in the the mobo and it booted So it could be the 24pin isnt seated properly. Good luck !

It is completely in. Please, I know a lot of times it is an obvious answer, but I have spent over an hour attempting to figure it out so far. I have tried everything and anything relating to the PSU and just haven't started taking parts out yet.

Honestly I can not think of a reason why the motherboard would be shorting because I have not touched it, but I suppose that is the next part.


The other thing that I have a question about is that when I have everything hooked up and attempt to turn on the computer, the ethernet port on the mobo actually lights up, but nothing else does.

Accept the fact that you might need to take out the motherboard and do a reseat. Yes it doesn't sound logical at first, but if it makes it work isn't that all that matters

I don't understand how you perceive touching it having anything to do with shorting of the board and this comment suggests you don't understand the concept electrically or perhaps even mechanically.

The first thing you should check is the front panel connectors. Is the front panel power switch connected to the pin header properly IE in the right position? One would think that would be the first logical place to start before actually pulling the whole thing apart duh!!!

PS it's very easy to plug front panel leads onto the wrong pin headers on a mobo

Ummm, either you do not understand the issue at all or we're misunderstanding each other. The front panel connections would have nothing to do with my issue...
