I'm been using a Radeon RX 550 graphics card with Adrenalin 18.5.2 on my Core Dell X5680 @3.33Ghz 48 GB machine running Windows 7 64 bit for the last year and a half for editing video in Vegas. Recently while I click on the 2nd monitor or drag while using Vegas my machine crashes and shuts off to a grey and white pixelated screen. When I reboot and disable the display adapter in device manager my system doesn't crash but of course, I lose some device functionality. Has anyone had these issues or can someone please provide me a solution. Thanks in advance.
