Building first PC ...any tips?

a word of advice.... when you put the cpu heat sink on make sure to have the thermal paste in an even coating on every part of the cpu. Make sure the ram is all the way in. And before you boot into the windows disk, boot up without windows installed into the bios to make sure that your hard drives are in the correct setting and that all the parts are registering properly. Make sure you get all of the mobo screws in because that ensures that it is secure and it won't budge. Organize the cables if you can. and next time don't buy everything from newegg. they overcharge on some stuff.
