BTOD with gtx 670

Uninstall the drivers and take the card out. Run windows update install all the updates. Then put the card back in and make sure all the wires are tight and properly connected then install the current drivers from nvidia since windows tend to install the old ones. You should be fine from there.

Thank-you for the quick reply! How would i go about uninstalling the drivers?
Finally, I don't know for certain the graphics card is the problem so do you know that's the problem?   thanks a lot!

I had the same issue when I added the second GPU in my system and I had to pretty much end up doing a clean install that resulted in a working GPU. So go to star>control panel> unistall program> look for nvidia driver and unistall. Turn off your PC. Remove the card. Plug the video cable to the motherboard. Turn on your PC, run windows update until you get the latest updates available. Install your card make sure the cables are done properly. Go to www.nvidia.com and find their drivers for your card, don't get the beta edition get the 310.90 and go from there. You should be fine afterwards!

Thanks soo much for the help, attempting fix now 

I now have another problem? Nout output shown when plugged in to other hdmi (motherboard)

OK. So did you do exactly as I said?

Currently, installing the windows updates, no graphics card detected. Hopefully you've saved me!

Ok good. Once it's all done you can do the remaining part. Make sure you have it plugged in correctly and that the power cables are connect properly and go from there.

BSOD (same error) Whilst installing updates do you have any IM service? I understand if you don't want too  

I don't have one bud. Last time I used one was 4 years ago.

Let's do this all over again. What make is your PC. I need all the info about, CPU, motherboard, RAM, Power Supply, Graphics card maker and where you bought it.

Thanks  

OK. I just checked that out. If what I said failed since that got mine working then you are going to need to do a clean windows installation. Move any data you have and re-install windows 7, make sure everything goes smooth. Then install the drivers for you card. Boot up your PC and do the install from bootup instead of going into windows. Put the DVD or whatever the windows is found on and do a clean install. You shouldn't be having these issues. Also, the store page doesn't show the version or make of your card. So what brand is your card?

The motherboard graphic output may switch off when a discrete graphic card is detected.
