I use edius 7, have a 3 monitor setup, one monitor is connected to a ati card, one monitor connected to the onboard gpu (in order to use gpu acceleration in edius) and one tv connected to a spark card.

I had some issues with the ati card, everytime I watched a film on vimeo the image would "twitch", sometimes a lot making viewing impossible, when I dragged my browser to the screen that was connected to the onboard gpu the vimeo film plays fine.

So I got a nvidia quadro k420 card hoping that would solve my problem but when I have inserted it into a free pci express x16 slot I can start up the pc, I get to see the screen where you can go to the bios or select the bootdrive, there it hangs for a while and then my screen turns black with a blinking cursor in the left top corner and it stays like that. Also while I am in that bootscreen no matter what key I press I cannot boot into the bios, my keyboard does give a light that it is being seen by the pc.

Is there anyone that has experienced similar installation problems with these cards? It should be pretty forward to install such a card I guess, the card draws power from the motherboard so there are no extra power connectors.

I now have installed my ati card again and all starts up fine.

I found some explanation on the nvidia site but my motherboard does not have that option, it said to go to the cmos setup menu and disable secure boot and set cms legacy mode to enabled, I"ll contact nvidia support, see what they have to say about it.

Dumb question, Noa... is the computer an ASUS? I read on a support forum for NVIDIA cards something about ASUS not allowing BIOS changes.

The motherboard is a gigabyte ga-z77x-ud5h, from what I can see everything is adjustable, not like on a dell pc where they do lock some settings. I"m surprised that something as simple as installing a videocard can cause issues.

Maybe try installing the driver first then in physically install the card.

That doesn't help either, where I got the card from suggested to update my motherboard bios to the latest version and I"m doing that right now (keeps fingers crossed :))

That did it, my motherboard bios update did fix the problem, the card now installed without a issue. Pfew...:)

Glad that's sorted. Most of the time it's a driver / bios issue.

Yeah but at this moment I got very nervous updating the bios, I still have a lot of editing backlog to clear and to me my pc is what a washing machine is to a couple with 12 children, if that fails the earth stops turning :D

I updated my Dell earlier this year, something similar, threw out the ATI card and put in a nvidia one, some extra RAM and a higher powered PSU oh! and tried unsuccessfully to upgrade to Win 8.1. The But that was before the season had started.
Unusually it all went ok no bios updates or anything, just drivers for the card and away it went.
