I had it working for about a week after I upgraded,now for some reason booting up is weird, sometimes it freezes mid booting sequence.Other times it starts but doesnt give any signal to my monitor,the fans run and its been turned on but it wont boot.And then even if it does boot it freezes after a couple seconds of entering my password,or while im entering my password.Also ive noticed that now when I try playing a demanding game like apex legends it runs terribly, the game cuts out and drops frames too 2 fps every other second (literal timing) where as before i played apex on max settings 60 fps for basically the whole day.Ive tried disabling auto updates on almost all my apps,Ive tried not playing any games and it doesnt matter. It progressively gets worse every day, faster freezes before i can even do anything.Just a second ago it froze in BIOS and after freezing repeatedly the last 5 boots. I don't know what category to put this under or whats wrong with my pc but any help would be appreciated,
thanks.
