So whats my story
I bought my first computer  just before Windows 95 came out. I had no real knowledge about computers, but I knew I needed to learn how to use one. Most people back then knew "DOS" (Disk Operating System) which was the first widely-installed operating system for personal computers.

Please be advised that my recommendations to upgrade your computer will only take between 20 to 30 minutes which will include cleaning out the dust (general maintenance). While over time, I have learned how to replace almost all components found in your everyday desktop computer, it is not a necessary talent today. The cost of todays technology is so cheap that most people just buy a new computer (it cost more to repair). However they make a wonderful "toy" for the average teenager to figure out how to repair one and a simply $100.00 upgrade can easly bring your old computer up to speed (depending on your use). The value is in the knowledge your child will aquire and would be the best $100.00 investment you can make in a child's future "open heart surgery" so to speak.
