I am starting to think my hard drive is going to hell. I thought I just downloaded too many programs to the laptop for school. But I did a total reboot of the C drive, and this computer is so slow, and it seems to freeze up for long periods of time. Is there any way to tell for sure if the hard drive was going bad? Also where would you all suggest getting another drive from? And what can I upgrade the ram to in this old thing? And last but not least, where should I get the ram chip(s)?
