Came home one night to find my computer on after I shut it down before I left for work. There is no patter to the shut downs and have run several test. Its not temperature related, i am guessing it's something to do with the BIOS or power supply. I do get a beep code sometimes and its saying my DRAM is out of sync but not sure that would cause my computer to restart

Motherboard: ASUS M5A97 LE R2.0
CPU: AMD Phenom II x4 965
RAM:2 2GB DDR3 SDRAM Kingston
Graphics: GeForce GTX 650 Ti
Power: Raidmax Tech RX-630Z 630W

Just installed new power supply and checked all electrical wires. When it shuts down it doesn't just shut down like the power has been unplugged, it turns off as though i have selected shut down windows.
