HELP - F4tal1ty A350 K4

Hi Guys,

I have an Asrock fatality a350 k4 gaming motherboard.

It stopped loading into windows and POSTing.

I tried some basic troubleshooting;

CPU, MOBO, RAM, GPU only - could get BIOS, but it has purple and green artifacts/lines running through the menu along the top and bottom.
When i use shell, half the writing is purple and white.

I cant work out which component is faulty, but i suspect the motherboard?

The system has been rebooting intermittently.

I have created a support ticket with Asrock, im just wondering if anyone on here can help me?

I live in Australia and Asrock isnt easy to contact...
