Hi,

Hope you can help me guys.

I built this spec:

cpu: Intel Core i5 3470S 2.90GHz Socket 1155 6MB L3 Cache Retail Boxed Processor
mother: Gigabyte GA-B75-D3V Socket 1155 VGA DVI 8 Channel Audio ATX Motherboard
ram: Kingston 8GB (2x4GB) DDR3 1600MHz HyperX Genesis Plug N Play Memory Kit CL9 1.5V
graphic: Zotac GTX 650 1GB GDDR5 Dual DVI Mini HDMI PCI-E Graphics Card
optical: Samsung SH-224BB SATA DVD Write Optical Drive | OEM
hdd: Seagate 500GB 3.5" SATA-III 6Gb/s Barracuda Hard Drive 7200RPM 16MB Cache
psu: Coolermaster Elite Power 500W PSU

(there is an integrated graphic card on the board as well).

It won't recognize the graphic card for some reason ( fan is spinning but that's it ).

I tried the following:
1) Having just CPU, graphic card and 4 GB of ram connected
2) Updating BIOS to latest version.
3) Updating chipsets to latest versions.
4) Trying the g. card with my older pc, (OCZ 500W psu, intel E8200, 2GB ram )
5) Dbl checking power connectors - all connected ( 24pin, 4+4 pin, 6pci pin )

Am I missing something here ?
I'm assuming that 500W should be more than enough, or am I wrong ?

Thanks
Peter

Is your GPU maybe not installed into the slot completely? make sure when you push it in it clicks. The fan may be running because its still plugged into the psu.

have you installed the power connecter?

ive just checked geforce website and it says there is a 6-pin power connecter on the cable that needs to be plugged into power it?

Don't know if this will help but its worth a try, I had to get a new mobo and when I plugged my gtx570 in I had the same problem, I would get picture from the onboard video but not from my discreet card. All I did was try pluging the DVI cable from my monitor into a different dvi slot on the graphics card ( mine has 2) and it worked! Can't explain it, but worth a try?

Your GPU has two slots because one is a single link dvi, while the other is dual link dvi. Single link dvi has some of the pins taken out of the male connector while dual link has all the pins. I also pretty sure if you are converting vga to dvi it'll only work in a single link port, but idk about that part.

Thanks for the explanation jthill, I just thought it was weird,because with my previous mobo (a P67) I had always used the top DVI slot and left the shroud that came with the card over the second slot. When I got my z77 mobo that was the last thing I suspected could be causing a problem, So it took me aaaaages before I tried that....

1) Card is connected to 6pin power from the PSU.
2) I took out the card few times, and put it back in - making sure it clicks.
3) 2 DVI slots should not make any difference. When I'm in windows (connected to the onboard graphic card), the system doesn't recognize gtx650 at all. If I try to run drivers fron nVidia, it can't find the device.

Today I tried it with another pc at work, which is something like this :
cpu: intel i7 920
psu: 460W
motherboard: some asus (no graphic card on board )

... and it worked fine.

I took graphic card from the spec above and stick it into the one I built - no power need for graphic card - and it also worked.

I'm starting to have doubts about this coolmaster 500W.

Any more ideas ?? ;)

Have you tried the following settings in your BIOS?

Peripherals -> Init Display First = PEG
Peripherals -> Internal Graphics = OFF

Also, what version of Windows are you running?
January 24, 2013 8:38:07 AM

Windows 7 ultimate.

I tried:

Peripherals -> Init Display First = PCI
Peripherals -> Internal Graphics = OFF

and it didn't work ...

I will try next as you suggested and see what happens.

According to p. 46 of the manual, setting Init Display First to "PCI" means that it'll look for a graphics card in the "old-school" PCI slot (which is not the same thing as the PCI Express x16 slot). It says to set it to "PEG" (presumably standing for PCI Express Graphics) instead, so that it'll look for a video card in the PCIe x16 slot.

tried it, no luck :/ 

Set it as suggested:

Peripherals -> Init Display First = PEG
Peripherals -> Internal Graphics = OFF

Hmm. I'm fresh out of ideas, then.
January 24, 2013 11:23:24 AM

I can't edit my msg above.

In BIOS when I do that:
Peripherals -> Init Display First = PEG

after save & exit when I open the BIOS again, Init Display is defaulted to AUTO again.

... However ...

If I put the g. card to PCIx4 socket it works !! Does it make any sense to you guys ?
