Possible solution for black screens, crashes, reboots

I see a lot of threads with the same issue, and I am going to post this in a few of them.  I have a Sapphire Radeon RX 5700 XT.  I also have an X570 motherboard (MSI MPG Gaming Edge Plus WiFi).  I have a similar problem where I get random black screens.  I hear sound for a few seconds and then the system reboots.  It seems to happen when the computer is idle or not under a heavy load.  Someone else posted a link to a video they found online with a possible solution and it worked for me.  I cannot find the post or the video, though.


The problem was that the video card actually does not work well with PCI-E generation 4.  (If you have a motherboard that does not have PCI-E gen 4, then this will not be your solution.)  


Many (but from what I understand not all) motherboards have a setting for the PCI-E slots that allow you to select the highest generation of PCI-E that it will accept.  The solution for me was to go into the motherboard's advanced BIOS settings and find the settings for the PCI-E slot where the card is plugged in. For almost everyone, it would be in PCI-E slot 1.   Change the setting from Gen 4 to Gen 3.  (From what I read online, we probably are not getting too much benefit from Gen 4 anyway). 


I have not tested this for more than a day, but I left my computer alone for hours.  It would have black-screened and rebooted after 10 minutes.  So far, no black screens, no crashes, no reboots, so I think it worked.
