I bought an Asus r7 260x around a year ago. A few months later i started getting blocks of misdrawn pixels. I've tried basic things like new dvi cable and reseating the card. Any ideas?
Not over locked. I've even underclocked it trying to stabilize it.
Yes, my pc is very clean.
Latest drivers, not at my computer so I don't know the release
Ok that is good to start. Also not every video card maker has qualified their card for windows 8.
While you get Windows 7 installed confirm the card works with windows 8.
A few video cards also demand to have the entire suite of .NET installed to work properly.
