There are people here who would be happy to help you, but you have not given us enough information to work with.
Might I suggest you start with one problem (most important) and see what we can do. I recommend that you only ask one question
per post so that we can keep focused. When to many questions are asked in a post, they don't always get answered well.
Among the information that would help us to help you, is a description of your system, your OS, added software and any specific
errors that the computer generates.
