NVIDIA Graphics Drivers could not find compatible graphics hardware

[KyleStevens_]

Hello, whenever I try to install my new NVIDIA GTX 770 drivers, it says that "This graphics driver could not find compatible graphics hardware" on the system check. The fans are moving, so I know its actually powered, also the card does NOT show up under device manager. I have tried removing all older drivers and still no luck. Any suggestions would be great, thanks.

Is the monitor plugged into the video card or the motherboard(integrated video)? What make and model of PSU are you using? Are the 6-pin and 8-pin power connectors plugged into the video card?

 

[KyleStevens_]

It is currently plugged into the Motherboard, the MSI version of the GTX 770 has two 8-pin power connectors which I have both plugged in.

 

[bignastyid]

You need to plug the monitor into the video card. With the monitor plugged into the motherboard the bios is using it and disabling the 770.

 

[KyleStevens_]

Ok I did that, now the monitor has no signal :/.

 

[bignastyid]

Are you using a dvi to vga adapter?

 

[KyleStevens_]

Yes, that was included with the card. I also tried using HDMI to connect it from the video card to the monitor but still no luck

 

[bignastyid]

With the DVI adapter you need to make sure you are plugging it into the dvi-i port. The 770 has 2 dvi ports 1 is dvi-i and will work the vga adapter, the other is dvi-d and will not work with a vga adapter as it only carries a digital signal. The dvi-i port is the one closest to hdmi port.
This is from a 760 but the port layout is the same on the 770.

Yes I used the one that is being pointed at but It didn't work, thank you very much for helping me out btw.. I really have no idea what to do here :I

 

[bignastyid]

Plug the monitor back into the motherboard and enter the bios and set the default video device to the pci-e graphics(peg)-> shutdown the system them plug the monitor back into the video card and power the system back on. Also whats the make and model of the power supply?

 

[KyleStevens_]

I assume this is already set, it doesn't say anything about a default video device in the MSI bios..

 

[KyleStevens_]

My PSU is Corsair CX600.

 

[bignastyid]

That is set properly. The CX series isn't the best but should work. Anyway you could test the card in another system? and/or try another card in this system?

 

[KyleStevens_]

My GTX 660 worked before, its only since I got this new card today that it hasn't worked.

 

[KyleStevens_]

I do not have another system to try this in either

 

[bignastyid]

Ok, bad news is it's probably a DOA card.

 

[KyleStevens_]

Ok I just tried with my GTX 660 and that has the same problem too, this is so annoying! D:

 

[bignastyid]

How old is the PSU? The CX series has longevity issues, they were a great budget option when they came out but time has proven they have issues. You could also try and reset bios defaults/clear nvram on the motherboard by using the nvram/cmos jumper or button(depending on the motherboard).

 

[KyleStevens_]

Very new, the build itself is new also as I have only had it all since July.

 

[KyleStevens_]

I would like to say a BIG THANK YOU to bignastyid, even though he may not have helped me he atleast tried and he broke down the problem, I eventually found out what was wrong and if you are having the same problems as I am, PLEASE follow all the steps that he asked me to do and if all else fails, CHANGE THE CARD TO A DIFFERENT PCI SLOT. It seems my 3.0 slot was faulty and changing it caused it to be fixed!

 

[bignastyid]

Glad to hear you found the problem.
