Video card not recognised?

TomMarshalI · Jun 13, 2013

Hi guys, I don't know if any of you could help me, been trying to find a solution for a few days now but nothing. I recently built a new pc and it worked great for the last week. I have a GTX 780 and have been playing games and everything and all good. But I randomly turned it on one morning and the computer doesn't recognise the card. The GPU powers up fine (fans spin, Geforce logo lights up etc) but computer says nothing is plugged in despite me running my monitor straight off it? I even took it out and put it back in and when I try to update the drivers from the cd or straight from Nvidia website i get nothing but a driver instillation failed message saying no supported hardware? Any ideas? Like I said worked perfectly last few weeks with 0 problems but now nothing! thanks

ASUS P9 X79 PRO motherboard
Intel Core i7-3820 CPU @ 3.60ghz (16GB Ram)
Windows 8
Corsair CX750 PSU

Quite strange...

Can you check in BIOS?

Yeah. I have that motherboard. I upgraded the BIOS recently (before I got my 780s) and have had no problem with the 780s.

What Bios rev are you at? This might be a hardware compatibility issue that gets fixed by a BIOS update.

Where about in bios can I check? Iv'e had a poke around in the advanced menu but can't seem to find any mention of GPU configuration or pcie slot choice? I think i'm probably being stupid and it's right infront of me but have had a good look and can't find any info in bios? thanks

i'm a bit of a noob im afraid (this being my first pc build). What is a Bio rev and how would I go upgrading it? Sorry again if this is super simple!

TomMarshalI :

With this motherboard, you can determine your BIOS rev level by booting and hitting the delete key to enter the SETUP/BIOS/UEFI screen. Once you're there, the BIOS revision level will be listed at the top of the screen.

If your BIOS rev level is 1203 or older, you need to download the BIOS converter utility from the Asus P9X79 Pro download page and update it through the ASUS BIOS Update utility in the setup menu. After that, you'd apply the latest BIOS update. If your BIOS rev level is already a number higher than 1203, you just have to download the latest BIOS update from the Asus P9X79 Pro download page and the easiest way to apply it would again be through the BIOS update utility within setup. The BIOS flashback utility is another way to apply the update, but the feedback mechanism that lets you know if everything is fine or not is not for beginners.

thanks for the help. Ok updated to the newest driver the the way you said, everything updated successfully and with ease but still no luck with the GPU. Again monitor is running through it with power etc but is not showing up in windows. Really stuck with this. Worked perfect one second, gone the next!
