Few a few weeks my computer has been running slow and the internet browser would freeze as soon as I logged on. I have Norton antivirus. Then a couple of days ago I sooned as i turned my laptop on it would freeze. So im thinking it must be the hard drive. So since I have a Recovery Disk that i got when i bought my computer I thought ill just erase hard drive and start fresh. I found this website white canyon which as software the will erase my hard drive for me. i install it then after about 15 minutes of running it it was at 23% then the screen went blue like my laptop just froze. Now when I boot up I get No OS found on my computer I put my recovery disk in but it does nothing. Could I just buy a new hard drive then use the recovery disk to get back on track or will I need something else. Im running Vista
