Re: Computer won't start after build
Yeah. Make sure you have your cables connected properly. That's an often overlooked simple mistake.
Just for your info:
I have had 3 computers so far which have done this. Press power, nothing. In 2 cases, the culprit has been a bad motherboard. The other was the power supply. Any other errors, as stated by a previous member, RAM, CPU, Video, etc, your computer would power on, but would beep at you to inform you of errors. If you can't even get turned on, it can only be 3 things. PSU, Mobo or wrong wiring.
OH! And check the back of your power supply and make sure the switch is turned on and plugged in. Another simple common mistake.
