Hello, I have a Dell Latitude D620 laptop that I bought in 2006 and it runs EXTREMELY slow, whether I am on the Internet or just doing basic tasks in Windows or MS Office. It has Windows XP, some basic software (like MS Office), and only a few files (because the hard drive crashed last year, so I only put a few files back on it, after installing the new hard drive). I know it's relatively old, but is there ANYTHING I can do to increase the speed of the computer, without buying additional memory? Any help I can get with increasing the speed will be greatly appreciated. Also, I don't know if this is a different issue, but sometimes the laptop seems to get too hot (at the bottom) after being on for too long. Thanks in advance.
