Hello, I just recently bought parts for my new computer and it is my first time putting one together. I have a couple guides and read the manuals that came with my parts, but for some reason after I plugged everything in I can't get the computer to boot up. I'll see a fan light turn on for a split second and then nothing. I'm not sure what the problem could be but I have an idea that I may have messed up plugging in a cord incorrectly somewhere somehow. However, I've done a check on it and still can't find the problem. Any ideas?
