I have recently got back onto this forum , I tried to download the Free Windows 10, which I had started on Tuesday 4th , having seen the screen say 25% recovering files and folders , it suddenly went quirky a blank monitor ,and my desktop was showing the blue light flashing, this continued right through until Sunday.
What did I do:
1: I switched off the computer on the mains for a good 10 minutes, this after several attempts no change.
2: On a switch back on the motherboard screen ASUS showed I pressed the F2 button , which showed the CPU screen , I then did F8 for boot.
3: This produced a blue screen saying going back the original version in my case windows 7, after several days of the blue screen showing restart with a clockwise circle movement on screen.
4: This morning early it went into the next phase, then went to a blank screen, I then repeated what I had done earlier by switching of the at the mains.
5: After the second showing of the ASUS motherboard page I went to the Boot symbol on the lower part of the screen , this was booting the computer without the need of the original Windows disc.
6: This after about 5 minutes or so stated it was taking me back to Windows 7 , I entered my password and then came straight on line.
