Computer
I do not have specific website to recommend. When I have any problem regarding computer, I will google it. For an example, recently, many encounter problem in msn ( keyport problem and bla, bla , bla , all the error code xxxxxxx appear ). Just google error code ( e.g. google 8844022 msn error) and find solution from expert. Follow step by step, most of the time , problem can be sloved. You also can get whatever software ( freeware, shareware) by “googling” it. Another example, google “how to uninstall certain antivirus software ( avast, nod32 and etc.)” if u can not uninstall that software. I still remember that one computer expert say there is nothing that you cannot manage to search in internet. I partially believe that, as long as you put effort to search, you will get it finally.
I think it is better to teach to fish instead of giving fish like our lecturer told us every day. So, start fishing ( but not phising-what does it mean, try to google it) today ^ ^.
