So, recieved my new computer today, put it all together, and when i tried to boot it, nothing happened.
After some troubleshooting i found out that if i take out the two PCI-E connectors out from the back of the GPU, the computer boots, but beeps an error message that indicates that it couldn’t find any VGA.
Here is my specs:
i would contact NVIDIA and ASUS. Sounds more like a problem with the motherboard. But it could also be a problem with the GPU. I Would blow in the PCI slot and see if that helps
Are you installing the GPU in the default PCI-Ex16 slot? When you say nothing happens when the PC is powered do you get it power up with all the fans running just nothing on screen?
Do you have another working GPU you can test with?
Are both the 2x2 ATX and 24pin ATX power connections true?
EDIT - Is the RAM installed correctly? In my experience it’s nearly always RAM that prevents a PC from booting first time. Try one stick at a time in each slot.
Yes, i’m putting it in the upper one. I can get it to run like that, yeah, but it turns itself off in some seconds.
Nope, no-one that is PCI-express.
Yes, both are plugged in.
Well, i have tried putting in just one RAM stick, then it boots, turns off after a few seconds, and then sometimes restarts itself. Then it won’t boot. Then i have to move the RAM stick, and then its the same thing all over again.
EDIT: i have just found out that when it boots, it boots properly, but just touching the PC makes it turn off again.
no onboard GPU eh? try an old GPU and if it boots, then the new GPU is the problem, if it doesn’t, then it’s the motherboard
all my old GPUs are standard PCI. it doesn’t fit in my motherboard. also nope, no onboard
you mean AGP? because you still have at least one regular PCI slot.
probably. i don’t know much about the different connections 
but none of my old GPUS fit in any of the slots 
I would say it’s the GPU since you get a POST error when the PCI-E power is unplugged.
well, there are some leds on the mainboard that randomly blinks, those are labeled “DRAM_LED”, “BOOT_DEVICE_LED” and “VGA_LED”.
Could it be RAM? in the book that came with the mainboard there is a list of supported 1600 mhz DDR3 ram, and my RAM is not listed there.
well if your ram wasn’t compatible then it would beep even with the GPU plugged in
also, I never used RAM that’s listed in my mobo manual, yet it works fine after 2 upgrades
How good is the power supply? You may need a better one.
it’s Corsair 650w, and brand new
use your warranty and replace the motherboard
yeah, probably going to call the company from where i bought it tomorrow, maybe they can help me…
suck tho, i was going to a lan party on saturday well, time to install windows on my old laptop i guess…
Make sure your memory is supported by the motherboard (the manual always includes a vendor list). Like Sersoft said, if the memory is not supported by the mobo that doesn’t mean it won’t work but that’s not always the case.
The first thing you should do with a new computer is go to the BIOS and set the proper timings and voltages for the memory. If you have to overclock the CPU to achieve 1600 MHz on the memory then I suggest you stick to a lower frequency for now.
People tend to overlook memory when building a computer, this is a very bad idea. Memory problems are a major pain in the ass and you really want to avoid them at all cost.
edit:
Note that the that the maximum supported memory frequency is 1333 MHz so when you set the memory frequency in the BIOS you’re gonna have to go under 1600 MHz unless you overclock the CPU. Don’t forget to set the timings and voltages, really important.
edit:
Same goes for the motherboard, supports up to 1333 MHz unless you overclock like I mentioned earlier.
the one i’ve bought does support 1600 mhz, but my ram is not in the vendor list
Besides the above, if you want to test if it’s the mobo, the graphics card, or your RAM, I would suggest doing a bare-bones system boot.
(Mobo, power supply, CPU (with fan), Graphics card, and RAM; nothing else) and see if it boots then. If it works, then systematically plug in each component till it doesn’t boot up properly. Log the last part, remove it, then try everything else.
If it DOESN’T then try another Graphics card or swapping out other parts for different ones that are supported with the mobo (if you have any).
About 6 months ago my 8600 graphics card blew up on me and I didn’t know (video stopped working, and when I did a reboot, it wouldn’t post; ‘beep’). This method is how I diagnosed it… person I live with has a metric shit ton of computer parts laying around, so it was pretty easy to swap out parts, etc.
That will help narrow it down. Then again it’s a lot less time consuming to just complain to the company about their faulty product (if you bitch enough you might get a discount but good luck with that). It’s up to you on what you want to do.
Sounds like a bad ground… which could be a problem with either the power supply or the case itself.
i think the bottom of the mainboard does touch the steel of the cabinet, actually. maybe that is the issue?
