Hii there friend~~
Well i'm here to help...and you know actually is quite fun to build your own computer by yourself!If you do everything yourself and everything is working it will make you feel real cool and clever!!
So first of all i'm going to put a list down where to begin and what to install first!!
If you say you stripped everything
1.So first of all always start of by installing your motherboard first into your casing.
2.when your motherboard is installed then install every component which connects to the motherboard itself like(CPU...RAM...CPU FAN...AND HARDRIVES) Don't connect the cables just yet.
3.Then install your power supply...connect every power connector carefully to your motherboard and make sure every component is perfectly connected.
4.Then install all cables and make sure you do some cable management otherwise your computer case side panels will not close perfectly....
5.make sure you connect your front panel connector in the right way on the motherboard and yeah that's basically all...
Make sure every component is at its rightful place and where it belongs...other wise you will run into some trouble...Double check everything and make sure the power supply connections is where its suppose to be.
If you struggle you know where to look for help
