Step 1: You need to buy the parts. You can either buy the parts at your local Best Buy or buy them online. I recommend buying you parts on the website called New Egg or PC Part Picker.
PC Parts you need: CPU,GPU,Ram,Memory,Storage, Power Supply and a PC case. Extra things you may need is an extra storage card, a ethernet cable, extra fans if needed and Windows 10, CPU Heatsink
First take out the motherboard and the CPU and install the CPU into the motherboard. The CPU looks like a square chip and you install it through the square shape on the motherboard.
Then install your ram, GPU and you ethernet cable if you have one. If you don't have an ethernet cable you can get a Wifi card and do it that way as well.
Install the motherboard into the case by sliding it in until it fits with the I/O shield. After you installed it in make sure sure it is secure by screwing it in with the a screwdriver.
Then install the hardrive by taking out the hard drive shield located in front of the case and slide the drive into it and put it back into the PC.
Install your Power Supply into the rectangular shaped side of your PC. Plug in the cabled by using the manuel for your specific model.
Connect your cables that come from your power supply to the motherboard,proccesor and hard drive.
You need the 6 pin cable from your power supply to plug i t into the graphics card, the 24 dual pin into the motherboard, the sata power cable into the hard drive and the CPU power pins into the CPU.
After you so all of this you have to heatsink power which is from the heatsink, so it's not as hard.
You have to attach the case fans to the power supply back adapting a 3 pin molex adapter to the PSU and then adapt the 3 pin connecter.
Plug the motherboards SATA cable into the hard drive. There will be two cables, so plug one into the hard drive and one into the motherboard.
On the back of your motherboard there should be a power on button. Press it and then turn on your PC and it should turn on.
Success! You have your very own PC and now you could use it to play games, watch movies or do any office work!! Good luck with your PC!!
