You seem to have multiple thread open pertaining to your GPU and the CPU. For this thread, please include/list your specs like so:
CPU:
Motherboard:

GPU:
PSU:
OS:
Mind also sharing the age of the PSU, apart from it's wattage and it's make and model? You might want to use DDU and uninstall the drivers for your GPU, before reinstalling them with the latest off of AMD's support site. I'd advise on installing the drivers in an elevated command, i.e Right click installer>Run as Administrator.
