Question Strange GPU issue

Hi I've been getting a really weird GPU issue. Every time I shut down or hibernate or sleep, the GPU refuses to start on booting up, displaying a blank screen. I have no choice but to force restart. On forced restart it seems there's a 50% chance it starts working, or I'm forced to restart again.

Restarting the PC normally instead of shutting down seems to allow the GPU to continue uninterrupted.

When the GPU does boot, there seems to be a 50% chance it'll fail as soon as I run any game, causing black screen. When it does run a game though, I'm able to play for several hours without interruption.

It does appear to fail after prolonged use though this occurred rarely. It mostly doesn't fail when running the web browser or watching videos

I've unseated and reseated the GPU and RAM, uninstalled and updated the drivers, cleaned out the dust and unplugged the power for an hour, and plugged into the wall outlet. All of these seemed to have had no effect.

My specs
Radeon rx480 GPU
Corsair CX500M PSU
2x Corsair vengeance 8gb ram
Wd 1terabyte hdd
100gb Samsung SSD on which the windows 10 is installed

Any help at all would be greatly appreciated!
