This issue started perhaps 5 to 6 months ago, probably after I updated the Radeon software/drivers. At first the crashes seemed to occur overnight, presumably while the computer was in sleep mode. After a few successive Radeon updates, the problem changed a bit, but it was the same driver identified each time.
I have since allowed the Radeon updater to determine 'the best driver for my Windows 10-64bit system'. It actually back leveled the drivers. For 11 days there were no crashes until two days ago - they are back, twice a night. I have used WhoCrashed to analyze the dump files, and each time, the same driver is identified.
I have read many horror stories about recent Radeon software, especially from gamers, which I am not. I have tried a few of the more reasonable suggestions to no avail, so now I'm back at the older driver package. Some of the suggestions involve replacing the Radeon hardware/software with Nvidia products. I really don't want to go there for financial reasons, so I'm about to try the drivers that were released on 03/24/22.
FWIW, I have not experienced any other issues with the RX-580 in any mundane applications like Word, Excel, Outlook, videos, etc.
Any current suggestions, other than Nvidia, would be appreciated.
