I bought my RX580 off amazon about a year and a half ago, and it worked fine up until about six months ago. My RX580 has been having periods of crashing my computer in which the screen turns a random colour, normally blue or black, for a few seconds, and then the screen turns off, my monitor doesn't receive signal and my fans spin very quickly. The only way I can then shut off my computer is by holding down my power button on my case. In order to temporarily fix this problem I have repeatedly had to both disconnect my GPU cable and reseat my graphics card in my motherboard following me booting it up without a graphics card and then rebooting with it back in. Also, when I try to turn on my computer following a crash my peripherals (keyboard, mouse etc.) don't light up and I either manage to boot into my computer and it posts, but not for longer than a minute before crashing again, or it doesn't even post. I know it is not my RAM or my power supply, or an overheating issue. My graphics card stays very cool (normally below 70 degrees Celsius) when doing most things e.g playing games. My computer also crashes when not playing games, and it normally happens after I perform some sort of action such as alt-tabbing or simply clicking. I have installed and reinstalled multiple sets of older as well as newer drivers as well. I would appreciate any help I could get as the periods of crashing are getting more and more frequent to the point where it is difficult for me to use my computer.
