Hi all. Ok was having "out or range" errors and "no signal" on display (Asus PG279Q ROG Swift 27inch) . Tested GPU and mobo and they seem fine. Tried safe mode but problem persisted. Have tested with another screen and different cables and problem is still there. Swapped to another PCI lane and problem went away for several hours then came back. Swapped to a different GPU port (video out) and problem went away but has come back. At the moment I am swapping between PCI lanes whenever problem comes back. I have updated drivers with no change. I have stress tested both GPU and CPU to see if any errors come up but nothing. I've changed to lowest settings with and without gsync and still the same errors. I have been told to RMA mobo and cpu as the cpu is now suspect. Anybody know what else might be the cause?
