Graphics Card Wont Boot

Hey guys,

I bought some new parts last week and I have assembled the rig. But the graphics card just simply won't boot. I tried two different cards, which work in another computer, but not this one. The fan on the graphics cards won't spin either. My motherboard does not have onboard graphics so I can not go into the BIOS.

Here are the specs:

Intel i7 920
ASUS P6T Motherboard
PC Power & Cooling Silencer 750W
EVGA GTX 260 Core 216 Superclocked 55nm
OCZ 6GB (2GB x 3) DDR3 Triple Channel Memory
Western Digital Caviar Blue 640GB Hard Drive
LG DVD Writer
Antec Nine Hundred Two Case

When I boot up the system, the fans on the case work, the CPU fan works, the optical drive works, but the graphics card doesn't work. I know this because the graphics card fan doesn't work, but it works on another system just fine. So the problem is not the graphics card itself.

I tried all 3 of the PCI Express x16 slots, no luck with any of them. I tried booting up with 1 stick, 2 sticks, and 3 sticks of memory, no luck. I tried 2 different monitors, no luck. I took out the CPU and put it back in, no luck. I tried two different graphics cards, no luck.

I am completely lost now and have no idea what to do. I have no idea what is causing this problem. Any help is greatly appreciated.

Do you have both 6-pin PCI-E power connectors plugged into the GPU? Have you gone through the checklist in the "READ before posting about boot problems!" sticky at the top of the forum?

Yes I have both of the 6 pin connectors in there. The other graphics card gets the power directly from the motherboard, and that card's fan doesn't spin either. So it's not the power supply that is the problem.

And yes, I went through the checklist, no luck.

So both the 8-pin CPU power connector and main 24-pin motherboard connector are also plugged in? Which RAM slots are you using? Be sure to double check your owners manual, but I believe you should be using the orange slots starting further away from the CPU.

Did you also perform the breadboarding step in the checklist to eliminate the possibility of a short?

Yes the 8 pin CPU connector and 24-pin motherboard connector are also in place. I can see the light come on the motherboard when I turn on the power. I am using the orange slots, confirmed by the motherboard manual.

I do not have a motherboard speaker, my case nor the motherboard came with one. I want to make sure I check everything before I go off to buy one.

Mine says SLBCH

I can't even access the BIOS because I can't see anything on my monitor because the graphics card doesn't work.

I'm aware that you don't see anything on the screen. I'm just trying to help you troubleshoot your problem. If you had a CPU that wasn't supported by your BIOS version you would have problems similar to the ones you're experiencing, but you should be good with the BIOS because you have the older C0 stepping.

If you have really gone through the entire checklist, including breadboarding and trying every stick of RAM by itself in each orange slot, it's starting to look like a DOA motherboard.

Alright I went out and bought a new motherboard. I plugged in everything and it worked perfectly out of the case. The display came up and everything. However, when I screwed it in the case, the same thing happened. The fan stopped working and no display. I unscrewed it and the fan works, but still no display. So the motherboard is not the problem.

Also, whenever I turn on the system, it powers up, but then loses power for 2 seconds, then powers up again. The GPU fan works, but no display on the monitor.

And since the system booted up once, I know that the RAM is alright. So could this be the work of a faulty PSU? Please help!

You shorted out your motherboard. make sure all the stand offs are in , ALL of them in the places where there are holes on the motherboard and no where else, make sure they are secure but not too tight. you probably will need to RMA this MOBO too , but dont tell them you shorted it.
