New Build isn't booting D:

post #1 of 8
Thread Starter 
*Updated*

I bought all the parts for a new PC, but the damn thing isn't working.

I turn the PSU on, and all the Mobo lights power on. I go to turn the PC on, and it just doesn't work. No beeps, clicks or anything.

It powers on for less than half a second and I can hear it trying to start up within that small time frame as well, then it powers down. The fans don't even get a chance to spin. All the Mobo lights remain on though, the PC just doesn't start. If I try to start the PC a second time, it won't even try to power on. I have to turn the PSU off and on again JUST so it can repeat the problem about.

I'm POSITIVE that everything is plugged in correctly and fastened tight. It's not the GPU as I've taken it from a working computer (and tried to boot without it) and it's not the RAM because I tested that out too.

Here's are the parts that could be problematic:

EVGA 750i
Corsair 750W
Q6600

All fresh out of their boxes. What is the damn problem?
----------
I got it working! ...Sort of...

Apparently there were two problems. One was that the Case fan wasn't plugged into the right spot. For some lame ass reason it HAS to be connected by molex (which I've never seen before).

The second thing I've yet to solve though. I can't power the CPU. The components inside the machine work when I don't have the pins plugged it, but the CPU won't and I can't boot. If I DO have the pins plugged in, the problem will be exactly the same as before.


Biggest case of PEBKAC ever.

Is there a voltage switch on the back of your PSU? Is your memory and proc seated correctly? Do you have the 4/8 pin plugged into the motherboard?

It sounds like it could be a shorting issue. To eliminate this you could just simply rebuild the system, see if that sorts it out.

Try hot wiring the PSU with a paper clip to see if it is booting properly.

No Voltage switch. Just on or off at the back of the PSU. Those pins are plugged in as well.

No idea how/what hotwiring the PSU is, but I'll rebuild the system if it comes to that...

Here

Basically it tricks the PSU into thinking it is connected to the motherboard, this way you can see if it is powering up correctly. And if you have a multimeter you can also check that all of the voltages are correct.

Hot wiring was a bit of bad wording on my part sorry.
