Installed new graphics card everything else is the same, it's weird because the BIOS splash screen doesn't appear anymore either. So I start up the computer, everything's fine, except for no BIOS splash screen, then windows 7 splash screen 'starting windows' comes up, everything's fine, then the monitor flickers on and off and suddenly I get the artifact, for every program, game or video, and in general across the monitor. reinstalled drivers, and optional drivers, don't know what to do
sys specs
AMD FX-8320
Gigabyte GA-LMT78-USB3
16GB RAM
520 W PSU
Sapphire Nitro RX470 8GB
Thanks
