Why did you have to reinstall Windows 7? Did you use factory recovery discs, or a recovery partition... or a full Windows 7 install disc? Make and manufacture of the laptop? Any idea of what the Blue Screen error code was? If you could edit your question and supply more information, you'd be able to get more help. – Bon Gart Jun 13 '12 at 5:21
My first operating system is windows 7 home premium, then i reinstalling by using windows 7 ultimate. so, here i just want to change from windows 7 home premium to windows 7 ultimate then the blue screen happens on my laptop – TOFIK Jun 14 '12 at 17:36
Did you purchase or download this copy of Windows 7 ultimate? Have you been able to identify what the Blue screen error says when it pops up? Why the upgrade/change to Ultimate? Did the system run fine with Windows 7 Home Premium? Again.. make and model laptop? – Bon Gart Jun 14 '12 at 17:40
i cannot identify what the Blue screen error, and I think if I use ultimate edition i can get the better performance (it is only by my thoughts true or false i do not know) – TOFIK Jun 14 '12 at 17:52
Better performance doing what? Better performance overall? Again... where did you get the copy of Windows 7 Ultimate? Did you buy a retail copy, or did you download it? I'm pretty convinced already you downloaded it, since I don't know anyone who would spend $300 or so on a copy of Ultimate, just because they guessed it would improve performance. Your issue could be with the copy of Ultimate you are trying to reinstall. You want a solution? Forget Ultimate. Reinstall your original OS with the restore discs. – Bon Gart Jun 14 '12 at 17:59
