Fatal PC Build?

So I finally got to build my PC which I ordered here: http://www.beamng.com/threads/5296-Christmas-Build-Ordered

PC all together, GTX installed except the power cables because I forgot them, but it started. It just had no display. So I pull off the GTX. Everything was on the PC aside from the GTX. It installed Windows 7, got to my desktop, etc. So then I decoded to put the GTX on. At first I forgot the power cables to it, I just stuck it on the motherboard and started up the PC. Knowing that, I shut it down 2 seconds after it powered up. Then I put the power cables where it told me to.

I press the start button (it stays lit while PC is on) and the light flashed once and it didn't start. Alright, let's pull the GTX off and try it again. Still nothing. Ok, reset bios by pulling all power for 15 minutes. Plug it all back in and still nothing. Only sign of life is a green LED light on the mobo that signifies it has power. So it was working until the final part. Did I fry the fucker?

 

Wait, you reset the BIOS by unplugging it for 15 minutes? That doesn't work.. There's a battery on the motherboard. You need to reset it by using the CMOS jumper while it's off.

As for whether or not you fried it, I don't really know. Try taking out RAM sticks one at a time. If that doesn't work and you don't find a solution, then have your motherboard replaced. (Should be covered by the warranty.)

 

Yeah the battery was off the mobo. The ram shouldn't be the problem seeing as it won't do anything. The ram worked before. Edit: nope, not the ram.

 

and your positive that you have all the right power wires going where they should? I know modular power supplies usually make it nice and clear. Yours has four modular plugs on it and these use PCI power cords which are for the GPU. I would hope that is what you did but I could see some using the included non modular 4 pin. That cord is meant for the motherboard and not the GPU so that may be causing the problem.

If the mobo has a speaker on it or wired in which some offer, it would give beeps during the POST that will tell if it is working right. I would say if you have the speaker on it take everything (CPU, GPU, RAM) all out and see if you can't get it to try and post. if it still won't post then the power supply or mobo has gone bad and I doubt it is the power supply in that scenario. if it will post then start adding parts back in one at a time and let it post (make beeping noises).

 

I would advise trying the system on several different power outlets.
I had an issue that was much the same when I first tried to run my system, it wouldn't power up when connected to a certain circuit in my home.
If that does not work, you may either have a bad connection from your PSU to one of your components, or have a dead vital component.

 

Take every plug, ensure it is firmly seated. I did the exact same thing and the issue turned out to be the 24 pin connector to the motherboard, while swapping RAM sticks I had accidently dislodged it ever so slightly and the system couldnt power on yet I did get a red LED coming on from the 4 pin connector.

Same goes for RAM sticks (easy to stick them in so that they dont quite make contact yet appear secure) and GPU's, but you say you've unplugged that so I doubt the GPU is the issue right now. GPU is rather large though so its perfectly plausible that you have done the same as I.

 

As others have said, unplug all the plugs from the motherboard and make sure everything is plugged in. When I was putting my system into my new case earlier I forgot to do the little 4 pin connector for the CPU and it wouldn't post. (No beep and nothing from the screen.)

If that doesn't work, yeah. Try getting it replaced.

 

Ive texted my dad to make sure everything is plugged in all the way, as I'm at my moms this week. If this doesn't work we're "taking this #*$*@&#-$72*#*# to the shop"

It's one thing if we built it wrong. But it was working...

 

Bad news. The shop told us the psu was shorted out, in a way we couldn't have caused it the way we built it. They said it shorted out the mobo also, so now I have an RMA to send those parts out. How wonderful, I'm a few more weeks out from enjoying this game.
