hi guys, i am no computer wiz so can help please be simple and not in too technical words 
basically i have purchased windows 7 home premium and when i install it, it starts working until it gets stuck on 87% of "gathering files" in setup. i have tried installing this on another pc and it works so it is not a faulty disk, also i have tried another disk and i have the same problem.
what do i do. both times when installing on my alienware m9750 (the laptop i am talking about) i have tried doing an update coz i don't really want to lose microsoft word and other files, but will do a complete installation if people think that's the answer.
Please help!
p.s. i have tested my pc with the microsoft windows 7 compatability check it says it should work
