Welcome to LQ.
Linux is not harder than Windows, but it is different. Be prepared for it to be different.
Also be prepared for this: LQ members will often ask you to do something at the command line. This is not to be geeky; rather it's because different desktop environments, such as Gnome, KDE, Unity, and XFCE, may have may have different GUI utilities and menu arrangements, but the command line is a great leveler--it is pretty much the same regardless of distro.
We will be happy to help you with your issues. Please follow the guidelines for posting a question
; they will help you provide information that will help others help you.
You might also get familiar with the lspci
commands--they can help you uncover details about your hardware for when you need to ask for help.
