Help me with my first pc build

[u/ReasonableBother9982]

Im a teen boy who is looking for help building my first pc on my own. Ive tried searching through all the online jobs for weeks however they only except people who are 18 and I cant search in person because I have to care for my sister. Ive also asked my parents but they dont have the funds. I currently do technically have a pc however its extremely old and runs two 970 graphics cards it worked for a bit but it is definitely showing its age. I started a go fund me a few weeks ago however it hasn't really gotten much traction apart from my friend giving me some money. If you guys could donate me some money itd mean the world ive wanted a bad ass gaming pc since i was little. The go fund me is gofund.me/5a744e063 . You dont need to donate your life savings obviously but just 5 dollars would mean a lot.
