I got a new power supply and a new motherboard for Christmas. I did have the LSP Ultra ATX Power Supply 600w and the Gigabyte 78LMT-S2 Ultra Durable Classic 4. But for Christmas I got the APEVIA 650W Beast Power Supply and Asus M5A78L-M Plus motherboard. After I installed the new components, my PC won't turn on. Everything is getting power because my LED lights on everything is turning on. But once I hit the boot up button on the front of my case, it won't turn on. Can anyone help? Please and thank you.
