I have an old laptop, a Dell Inspiron 9100, it has been a very reliable computer for 5 years but I am now having some issues...It takes forever to boot up and then it is so sluggish I can not even use it. My question is...Does this sound like a memory issue or a software problem? I am 99% sure it is not a security issue. I have always had AVG; Spy Sweeper; Zone Alarm on the system with AVG and Spy Sweeper doing daily scans. Thanks to all of you that have helped me start to learn more about my computers! If it is a software problem, how do I go about finding the problem if the computer is to slow or sluggish to use? Thanks!
