Hi friends, My laptop was working fine. I was just trying to reinstall win 7 in it, but as i was reinstalling it got hanged in between.So I took my harddisk in my frnds lappy and installed it. Now when I start my laptop then it load fine, but after the loading symbol of Windows , it stops there and does not move ahead to prompt for login screen, very few times it start nicely but after that when I start working in it it gets hanged there. If I starts in safe mode then it works nicely without getting hanged. I tried installing win 7, linux on it but installation process also gets stuck in half way, Can anyone tell me what problem can be there?
