Ok so my computer has been freezing on startup, blue screening, and shutting down randomly for the past 1-2 months. I have set up various threads with all my problems in the past. It seems to have been fixed at random times with little to no interference. It was fixed for the last 12 days at this point before it blue screened when i started up tf2 just now. Now it freezes on welcome screen. Is it worth trying anything?
