step one-
REMEMBER THE FRICKIN SPACERS!!! If you dont remember to put the spacers in between the motherboard and the case, you will fry your motherboard, and go through a month and a half of RMA's (like me lol)
step two-
Wire all those annoying case-motherboard connections, because its alot easier to reach the connectors with the board outside the case
step three-
making sure that you don't have anything under the motherboard except spacers, put motherboard in case and screw in
step four-
insert CPU according to directions given to you by CPU company
step five-
set up the rest of the PC, you know what to do
step six-
plug everything in
step seven-
find in motherboard manual the right button to get into BIOS. Press on button, and then hit the button to get into BIOS. Configure BIOS as you please.
step eight-
if you do not have an OS in the hard drive you put in, install it now. if you did, you will need to repair your OS. This will take some time...
And thats it. you're done! you have a custom rig of gaming power! and if theres one step you need, its the one involving the SPACERS!!! good luck!
