Need some help here do I have a bad GPU

post #1 of 6
Thread Starter 
Hello I am new here looking for a little help. I have 2 550 GTX "I know they are not the best, as I dont do much hardcore gaming. I want to use this setup for my music studio stuff" I have 2 screens currently running and connected to the first card. I just got a third screen but when I connect it to the second GPU the driver crashes "nvlddmkm.sys" and the system also will not boot windows unless I disconnet the third screen.

I have also listed PC specs here

have you tried to uninstall the drives, then hook up the other monitor and install drivers again?

Ok so I took the card and tested it at a friends house and the cards works fine till the driver is installed then it crashes. So I am going to say its a bad GPU. Now should I buy a new 550 or go with an AMD card? what do you guys think?

The only Bad cards are the ones not on the market for more than 6 months like mine.

Sounds more like a driver issue not a card issue. Have you tried Beta drivers?

No I will give them a try now with just the one card installed
