Help a newcomer build a gaming computer

Please explain like I'm five. I have limited experience with computers, their parts and software. I know the basics, as far as what parts it takes to build a functioning computer; but beyond that I have no idea what I'm doing. I'd like to spend ~$1000 or so, not including the peripherals. As far as the games go, it'll be mostly steam games and maybe gta5 or black ops 3. I'd like to run full HD and have an SSD for faster loading, or do I need both an SSD and a hard drive? I don't plan on needing a bunch of memory, but like I said I am not 100%, hell even 50% sure exactly what would be the best setup. I don't need any fancy parts, or ones with lights etc. just a basic computer that easily runs CS:GO and other fps/RPGs. Please help me out!!! Thanks in advance. Hopefully you'll have fun picking parts and shopping for me! ;)
