[SOLVED] Video freezes but sound continues requiring a hard reboot.

[ahkmedwithers]

When using my pc around 1-2 times a day the video will freeze whilst sound continues to play through my headset, if left frozen for around 30 seconds it turns black and this requires a hard reboot to fix. These freezes occur randomly and can occur when the system is idling and under no load, and stress-testing both my CPU and GPU didn't flag up any errors. This also freezes my RGB keyboards lighting patters. I've used windows memory diagnostic to check for faulty RAM and have also reseated both my RAM and GPU multiple times as well as changing the PCI-e riser that I use. I've tried using DDU to rollback video drivers to a known stable version but the crashes continued. Is my GPU broken or is there anything else I can try?
