I am having a dilemma. My computer suffered for the blue screen of death, hence i need to reformat vista. When i first got vista, i put the license sticker on my PC but the sticker was defective and didnt stick very well. It eventually fell off and was never to be seen. It didnt occur to me that this was the only copy of my product key i had and now that i am trying to reinstall vista its become a huge problem. I was relieved to find the page with the SIW.exe method and since i havent formatted yet, i can still perform this trick. The only problem is, my computer cannot perform a successful boot up. It hangs on the Microsoft corp screen with he green loading tube and never ends, and if it does end, it hangs on a black screen for too long that i just give up and turn the machine off. I have tried using safe mode, but it also hangs after it loads all the necessary files and i have tried turning power off for one minute but still no luck. I really do not want to purchase another copy of vista just because of a stupid sticker and especially since windows 7 is on the horizon. Does anyone know how to get my computer working? Also, if i call Microsoft can they issue me with my product key? Surely there must be some way.
