I picked up a Gigabyte RX Vega 64 to replace my old R9 390. When I turn on computer it loads fine, but I get lock ups when I play any video or surf web sites that have video, tried multiple browsers... Chrome, Edge, Firefox and explorer, all do it... But If I reboot the computer it's fine after restart, only does it from a cold boot.. so basically I have to power up then reboot the computer to fix the issue. My specs are.. Asus Rog maximus IX Hero motherboard. Intel i7 7700K @ 5Ghz (Water Cooled) 2x G.Skill DDR4 F4-3200C16-8GTZ memory Gigabyte RX Vega 64 Corsair RM 850x Power supply I've tried all released drivers for the RX Vega 64 currently using latest 17.8.2 I also tried not O.C. the system same issue.. Any ideas?
