Today I had to manually restart my computer 5-6 times and it's been like that every day. I was infected with some virus before and I got tired of trying to get rid of it(my antivirus wouldn' remove it). I decided to format the harddrive and do a clean install Vista Ultimate. That went well but now the computer freezes too many times in a day. It freezes randomly when running IE or just when I'm trying to install something. It's a fresh install and I need to reinstall some programs I had on it before but the freezing problem just wouldn't let me. Can anyone help me figure out what's wrong?
