My laptop, Asus zenbook infity Windows 8.1, starts the Asus loading screen. Then it jumps to a Windows loading screen. It is written: "Gjør Windows klar. Ikke slå av datamaskinen."(readying Windows. Do not turn of the Computer). After the Windows loading screen runs for about 15 seconds, it jumps to the Asus loading screen and the loop is complete. I have pressed f9 and entered the Windows diagnostics/repair tools. I have tried everything, it wouldn't run successfully the "forny PCen"(renew the computer) or "Tilbakestill PCen"(reset to a previous version) tools. I tried the safe modes, only safe mode with cmd worked. When I logged into the computer, I ran successfully explorer.exe. I did run the tweaking.com repair tools, it didn't fix the problem. What should I do?
