Cousin says might be heat issue on your graphics card.

He said if you have adrenalin 18.4.1 get rid of it OC is bad.
He said usually says sometimes the thermal paste is crap on cards that changing it helps also, if nothing else helps time to change it out for nvidia as AMD graphic cards are junk.

Make sure you have proper cooling as HP computers tend to overheat as well windows 8 also outdated platform.

10 gets more support which means hardware support and devices, but if not its probably a issue with overheating.
