I sent in my Alienware to remote assist for them to fix an issue of my laptop not turning on. After I got it back from them it takes 10 minutes for my computer to start up and always says "diagnosing your pc" or "analyzing". SupportAssist is always popping up and I have no idea how to get it to go away? Also, my computer will always black screen randomly and go to the Alienware loading screen and say "please wait" about every 10 minutes. I have no idea what to do? I've contacted support over 15 times and nothing has worked. I've downloaded new BIOS, new operating system, everything.
