So I finished assembling a new PC yesterday (Xeon X3470 with GTX 960). It would turn on and all the fans were running, however there would be no output on my monitor. So I troubleshooted a little, moved the RAM, etc and earlier today a screen finally appeared (I forget exactly what is said, but it was something about being unable to boot). So I turned it off, plugged in my Windows Installer USB stick, turned it back on, and of course, no more output on the monitor again. I tried troubleshooting some more but ended put taking apart everything, and reassembling it to see if anything would change. Now, the PC won't even turn on (nothing happens when I press the power button) even though I am pretty sure I assembled everything correctly. Do you guys have any tips on how I could possibly troubleshooting the PC not turning on and then not outputting and display signal? Do you guys have any experience with these same problems and have any guesses on what I could be doing wrong? Any help is greatly appreciated, I honestly have no idea what to do right now and I'm afraid I just wasted my money.
