Hi there, I've recently started getting the dreaded grey screen with vertical lines whilst gaming. My card is a Gigabyte Windforce R9 280. I did a search on some other forums and it seems that this issue is most commonly associated with the ATI 5700 and 5800 series of cards. My card is slightly newer but it does have DDR5 memory, something which was cited as a possible cause of this issue. A couple of months back, my G25 wheel started disconnecting sporadically. It started with momentary disconnections and deteriorated to the point that it now goes limp and lifeless before the initial calibration has finished. I've checked it in a PS4 to make sure it's not the wheel itself at fault; it seems to power up and calibrate fine (although it's not compatible to use with a PS4). I mention this because I was wondering whether the grey screen issue combined with the USB disconnections might point to a motherboard failure. Can anyone shed any light on this issue? Thanks.
