This happened after i changed something in the bios. Ive had someone try to repair it but they didnt know what was wrong with it. They removed the cmos to reset the bios but it didnt work. And know i have no idea how to fix it. Anyone who know what the cause could be?

You must remove battery and turning on and press and hold Alt+CTRL+Del for 10 s, then you heard a shout beep and next it solved. you can boot it and continue
