my asus notebook is a new one
i bought it from our country countrys capital city Mal'e
I used it for 4 days. it works good
But today, when i started it, it shows the bootmenu, but it havent clicked any key
Then I restarted it several times but it didint show the login screen and also when it opens it didint show windows logo and processor name
Is there any way to fix this problem.
