 I'm here to learn a bit more about computer hardware, motherboards, and something like that.
 
 I'm a computer enthusiast at high school.
 And i am started to learn about how to fix hardware problems on computers or laptops since i graduated from high school.
 
 I got a broken laptop and searching for some informations about the motherboard, and here i found badcaps.net is one of the great forum on the internet.Comment
