Ahh thanks for the replies guys, really appreciate it, I managed to find a fix for this which was as you said, disabling GPU acceleration, but I couldn’t edit or amend the post because I’m a newbie 🙂
Thanks a lot though! Any idea if I should be concerned about my GPU? Or think it’s more likely to be driver based? I’ve got a 560ti and it got through a few G80memtests fine..
Thanks again 🙂
