This post is more to share something I learned, recently I have installed a network adapter to my computer and I had trouble with mysql and apache they didn´t wotk fine and I took a out my network adapter and reinsralled everything but couldn´t make even thought I formate my drive I asked all my friends and no one could gave me a solution after a while I asked a friend who doesn´t know to much about apache ot mysql but he told me maybe my bios was actualized, I thougth it was a very weird Idea but tried and finally reset my bios and everything worked. So next time some thigns are what they don´t seem.
