i have upgraded to vista just today but that didn't go exactly as i expected it to be and it didn't work,so i chose to rollback to windows XP  instead,that didn't go right too and my computer doesn't even boot now and if my brother saw that he'd be so pissed off as i am and he'll blame it on me as always

the reason why i'm pissed right now is because my computer has a problem with my graphics card and it doesn't work today,that's why i'm gonna upgrade to vista which i heard was good BTW and right now i'm stuck with the built-in one which is no good that most games like Oblivion & NFS:Carbon Doesn't work on it
