Thanks for the reply Dragon
It's a new computer I haven't had any other card except this one and I have installed the latest drivers. I even contacted customer support and they asked me to download a certain driver which didn't work.
My best guess would be it's a hardware issue. Exactly what though, I have no idea. If I was a betting man I'd say it had something to do with the power it's receiving, but I'm not too sure about that. Isn't there a program I can download to run a diagnostic check?
Oh and the monitor works fine on my other computer so I've ruled it out as being the problem.
