I am gathering parts for my first computer build. What I am wondering is what is the minimum components that I would need to turn on the computer. I know what parts I need to have a complete system, but I am wondering if after only gathering say the case, cpu, and motherboard is there any way to see if each part is working properly. What parts would I for sure need. I have heard different answers from other people but just thought I would try it out on all of the experts here. I know this sounds like a stupid question but I am just wanting to make sure that the parts I am getting are working the way they should.
