When PC does go down, I usually first refresh my page about 3 times to check and see if it is my browser or internet that is messing up because PC does go down it acts similar to the way that my browser and/or my internet acts when they are messing up when I try to access PC. Then once I see that PC is down, I'll either watch something on YT, listen to music, watch a movie on Netflix, play a game, I'll just do something and check to see if PC is back up after one or two hours and if it isn't, back to doing one those things for another hour or two until it is back up.
