A few weeks ago, my wi-fi kept turning on and off. Sometimes it wouldn't even connect and would just keep saying limited access. Then today my computer screen turned blue and said "Kernal Data Inpage Error". The computer restarted and said PXE over iPv6 and that didn't work, then it said PXE over iPv4 and that didn't work as well. Then it went to a black screen and said "No boot device found". I restarted my computer several times just to get the same screen every time. On the 6th or 7th try, I finally made it to the start menu. Then the next day, the same problem occurred and now I can't even get to the start menu. If I press F2 or F12 and then press ESC, it will say "Checking Media [fail]". This is a new computer I purchased a few months ago.
