Many folk popped in a replacement motherboard and found Windows would not boot.
But this is only the tip of the problems here. Why did it want you to hit F1? Did the owner clear the CMOS, have a dead battery and didn't re-setup the bios values?
Have dell desktop running windows 10. I turn on the computer goes to american megatrends . hit the f1 key and goes to blank page. Windows won't load up. There a way i can do to get widows to load up?
Thanks
