Question GPU cutting out

[Kurt_16]

Hey all, i just got an ASUS RX Vega 64, put it in, and updated drivers etc.
Then changed the resolution and the GPU started cutting out and randomly, thank god i'm not epileptic.
But i fixed once before on the msi afterburner. But this time its running the correct mhz, clockage and memory mhz.
Can anyone help?
