Hey guys, so I just built my first gaming pc. Everything is working perfectly except the graphics card. The fan spins but it isn't recognized by windows or the bios. Ive made sure everything is hooked up right and seated correctly, when I turn the pc on I can hear the post beep signaling everything is okay.
A little info: When I did my first boot the graphics card worked fine, I was typing the key to windows 8 into the set up when suddenly the pc shut off and restarted, and from then on my monitor would just say no signal when I had the hdmi hooked up to the graphics card, but the onboard video works just fine.
ASUS sabertooth V77 motherboard
intel core i7-3770k quad core 3.5ghz processor
EVGA GeForce gtx 680
g. skill 8 gb gddr3 1600mhz ram
corsair 600 watt power supply
cooler master haf 932 advanced blue edition full atx tower
Do you guys think it could have something to do with the power supply not having enough power to power it fully along with everything else in my case? I know the minimum required for the 680 is 550 watts so I know I'm cutting it close. Plus the power supply was only rated at 80 plus bronze.
I am going to pick up an 850 watt gold power supply tomorrow and try it regardless, though I feel like the graphics card might be dead. I was hoping I wouldn't have to RMA it but its looking likely. Let me know what you guys think please.
EDIT: I forgot to add that under device manager there is an unknown device with an error that says it failed to start, its under the PCI communication devices
try this..make sure on the mb the 8 pin atx power plug is locked down. if it not there wont be power for the pci bus. also make sure the gpu has all of it power plugs in tight. the sabertooth mb has a muiltplexor chip for the pci vidoe slots. if your running a ib cpu go in and set the pci bus speed from 3.0 at 16 mode to pci 2.0 mode and see if the video card works. also if it not showing up try moving the card to the other pci video slot. also check under video main card output you turn on ipgpu muilt monitor support..if your on the ipgpu and that set to disabled the gpu wont turn on.
Well, just decided to RMA the GPU AND the motherboard just to be safe. Sent the gpu out today, sending the motherboard out on Monday. I also ordered a corsair 7850watt power supply that is rated 80 plus gold. hopefully all my problems will be solved. Really looking forward to seeing what kind of power this card has
