I started out as a livingroom tech teaching myself. Today it's far easier to work on these things. To help you get better aquainted, I have some suggestions.
#1, Computers for Dummies by IDG Books is a fantastic and informative way to learn PC's without having to learn the language. They keep it simple to understand and in laymens terms. The also keep the book lively with whitty humor.
#2. READ YOUR WINDOWS MANUAL... OMG I thought I knew some stuff until oneday in the tub I read my Windows 98 manual, I learned sooo much from that book.
#3. You need to pick a specialty. What intregues you the most about computers, see you have hardware, software, programming ,networking, antiviral, data entry, etc... you need to find a subject that intrests you. Learn about it first and thru it you will find the next subject and the next and the next.
#4. I have an old Yahoo Group that I once ran which is still in use today where I post how to's and free software to help you work on PC's. http://support.comstar-computers.com ... Use this site to help yourself become more acclimated.
