Me to unplug USB cords and such. But you can try that and tell what lead you to install the OS. Why it matters is you may have a machine that crashed due to some hardware issue and you thought reloading the OS would fix it. The full story can help.
I have a dell 4700, about 4 years old,and I'm retoring windows xp with the original installation cd. when I run the cd it will make it through the first few steps. I click on xp install, then I say yes to the agreement, then I put in the key numbers, then it will copy files to the computer. then it wants to restart,but it sops there and goes back into the old windows. but right after it boots if I click on xp setup, it goes into a black screen with a small 1/2 inch line flashing in the very top left corner of the screen and stays there forever, or untill I shut the machine off,why is it not following through with nthe setup?
