Can't reach desktop

I have a PC that was working fine 3 weeks ago and havent used it since. I turned it on the other day to use it. It booted up, got to the 4 blue boxes for windows and expected to load my desktop but it didnt. I tried using gparted live and then install windows 8 again, saw the 4 blue boxes again and loaded devices and then no desktop again. What could be causing this?

I tried using 2 different HD's. 2 different dvd players, 1 integrated video card and 1 I installed. I have tried windows 8 and 8.1 but cant seem to get to my desktop. Can someone plz help.

thx
