I suggest you connect an external HDMI monitor to the HDMI-out of your AIO pc.
if display on the external monitor is stable but built in display flickers, the built in display is defective.
if both external and built in flickers, it could be a faulty display adapter. try a clean install of Windows to see if that helps
