ITT TECH!!

ok... I am stuck on what I want to do. I dont want to own a daycare business anymore. I am very good with computers and want to major in something dealing with computers!! I have no idea what area. From what I have heard they're many different areas. Maybe someone can help me out because the more I look the more confused I get.
I love working on computers and figuring out what is wrong with it. Everytime there is a problem with my computer at my moms house they always yell "Brandie, come fix this!" or "What is wrong with this stupid thing?" Im always right there trying to fix it. If my mom thinks I cant do it without messing something else up she'll call the people and Im always right next to her telling her exactly what they are telling her to do.
So can someone please help me!!
