New computer causing problems

[Madina]

Hello. I built a new computer. All is good, except for when i try and install windows. Everytime i have to reformat the drive before windows will install it gets to 4% and the picture disappears but the computer keeps running. I suspected it was a problem with the graphics card, so i changed that for another one to see if it would make any difference, it doesnt

Im really stuck for ideas on this. Any suggestions (or a solution) would be brilliant.
