Question Windows 10 red screen flicker

You might want to uninstall your GPU drivers and manually reinstall the latest drivers found of your GPU manufacturer's support site.

Are you on a laptop or a desktop? That TCO '03 sticker indicates that system is very old...
its a desktop
and yeah monitor is old

could it be that monitor is the main issue idk.
also i tried installing latest drivers and my games started crashing giving error
radeon wattman settings restored so i reverted back to recommended one and again i have the same issue but with different color

GPU is RX480
