Hello,

Today I purchased a GTX 670 card from Pallit paired with a Z77 Extreme4 motherboard from ASRock.

After putting everything together and starting the PC up the monitor would stay in stand by mode, so I tried the on board GPU which worked fine. As a result I tried moving the GTX to the other PCI-e slot, the non-PCI 3.0 slot. It now appears to work fine, or at least it now powers up the monitor, I am installing Windows as I type.

So - is this an issue with the mobo and I need a replacement? Or is it a case of needing to update the bios, which I find highly unlikely, or some other fix?

The motherboard surely has to be the most annoying piece of hardware when it goes wrong!

Many thanks for any suggestions

As a heads up, I'm also running;

i7-2600k
16GB Corsair DDR3 1600
1 SSD
1 SATA HDD
1 SATA DVD
A few case fans etc.

That about covers it, the reason for buying the board was to install another GPU later in the year, doh.
 
Groan, it appears to work with the HD6870, I get a picture and everything gets past the BIOS without issue.

I cannot tell whether this is good or bad news, I guess it means the PCI-E slot isn't fried? But then I am on the latest BIOS at the bloody GTX 670 isn't working.
 
I take it back, put the GTX 670 back in and in a true "I wonder why I haven't tried this yet" moment pressed the clear CMOS button and hey presto, we're up and running with the GTX 670 in the PCI-E 3.0 slot, yay!

I do wonder how long it will last and what setting in the BIOS has changed it all mind, still at least now I can play around a bit with various settings and (hopefully) get it working again if I mess up by clearing CMOS, yay!
