I've just gotten my new EVGA GTX 970 SC to replace my aging GTS 450. I'm using Windows 7 64-bit and after the starting windows screen I get no display out of any of the ports on the graphics card. I am only able to test the HDMI port and the DVI-I converted to VGA for an older monitor. Both monitors have the same problem. My monitor displays no signal and the computer continues to boot. I can access my computer via remoting software. I know this was issue a while ago but I haven't found anything that fixes my problem. Ive tried Nvidia's 344.80 hot fix and I'm also using Nvidia's latest driver which are 347.09. I cant find anything that will get the card to work during windows. Safe Mode works just fine. Any Suggestions?
 
Here are my system specs if need be:
AMD Phenom II X4 840 (3.2Ghz)
AsRock M3A UCC
8GB Corsair Vengeance
EVGA GTX 970 SC (My old cad was a KFA2 GTS 450 1GB)
500W Cooler Master Power Supply (I don't know its exact name but I've triple checked to make sure its compatible with the card)
 

Hi, I have yet to fix it. I worked out that my motherboard BIOS needs updating but as it is updated as much as it can be, I can't get it to work meaning it's not compatible with the motherboard. If you find a way to fix it let me know. Hope you find a solution :)

Hi, mogumaster,

Your problem sounds exactly the same as mine. I tried everything and managed to work out it was a motherboard incompatibility issue (well it was for me anyway). I replaced my older motherboard with a newer one and it works fine. (Incase it helps, I went from a asrock m3a ucc to a gigabyte 78MLT.) That fixed it for me.

Maybe a BIOS update may fix it.


Good luck with solving the problem, I hope I've helped you. Hopefully you can get your 970 chugging along soon :)
