For a very long time now my disk buzzes like crazy on startup. It takes an incredibly long time for it to go away so I can finally use my PC again. The buzzing basically shakes my entire desk . Yesterday I tried to boot but got an error saying “Reboot and select proper Boot Device” which strangely also went away after a restart. However, today, I got a Blue Screen of Death with the '' Kernel Data Inpage Error'', and upon restarting it took my PC 10 minutes to start up. My disk is regularly at 100 percent at various times for no reason and I have no idea what to do anymore. Thank you for any help.
