This is my first build, I have had several other off the shelf computers and I wanted something better. I currently use it for gaming and will be used for streaming movies to the t.v. as well. After watching lots of videos online I was pretty confident in my skills to get the job done. I built it out of the case first and was elated when the bios popped up on the screen during the test boot. After settling down a little I got to the job at hand and put in the case and installed the water cooler on the cpu. I remember someone saying in one of the videos to leave the side off the case for the first boot, otherwise it wouldn't boot. I did not head this advice since I wanted the fan on the side hooked up and put the side on. After pushing the power button...nothing. Thinking that I had simply put the power button on the wrong pins, I took the side off and looked at my manual everything was right. I took it off the pins and tried to jump it...nothing again. I was now pretty scared that I had broken something when I was installing it in to the case or had an extra offset on the case that was shorting something out. After several more attempts, I was pretty disheartened and decided to take everything back out and build it out of the case again. Got it all out and hooked it back up to nothing. Now I was sure I had broken something. After looking around online on how to test my power supply and motherboard, I found a fancy tester for my power supply that was supplied from EVGA. Hooked it up and the power supply was good. So I had power, but no power to my board. By this time I was pretty frantic and trying to think of anything I could that I might have done wrong. I unplugged everything and went through the power supply cords making sure I had them all correct. When I unplugged the 24 pin from the power supply I noticed that it wasn't pushed in as far as it could have been. Pushed them all back in, this time with a little more force and success! So now I had to put it all back in the case... It was a learning experience that I will never forget, and am looking forward to my son getting a little older so that I can build him one. Right now he has inherited my ASUS ROG Laptop, which he loves. Sorry for the wall of text, just wanted to give my experience. Thanks!
