So I purchased an XFX Radeon RX 470 RS Black Edition 4GB the other day online, which Arrived yesterday to my very short-lived delight. Almost immediately upon installation, I discover that it refuse to hold a constant signal to the monitor I am using with a hdmi cable. After a number of attempts at fixes through Driver-fu, I am at a loss as to what to do, being not especially tech savvy. I am running a 600w psu, the mobo is a gigabyte ga-z77m-d3h-mvp, with 6gb of ram (would be 8 but one of my stick busted) with a core i5 3570 cpu.
To elaborate, when the fault occurs, the screen will cut to black, then to the tv's no signal place holder.Sound can still be heard, although if from a program it does seem looped, but if from WMP, it appears to play songs as normal. Only a hard reset from holding down the power button can do anything at this point.
