Yesterday evening, i shot the system down without waiting for it command like;

SYSTEM: there are still some apps runing, "shutdown anyway" or "close app first"
and this morning as i on the system of which if it boot, i will tell me i should enter my password but all i see is a blank screen with the cursor display

U see the proble is because u shot d system! Is it by d head or d balls? Lol!

On a more serious note, u probably have a virus infected system or the windows os is broken.

Try and restart while tapping d f8 key. When it brings up the menus, select safe mode.

If it still doesn't bring up anytin else apart from d black screen, drop ur whatsapp phone no and I'll buzz u and walk u thru a process.

Take kia
