I recently build a home server using the following components:
PSU: CORSAIR Builder Series CX430 V2 (CMPSU-430CXV2): http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026
Motherboard: BIOSTAR B75MU3+ LGA 1155 Intel B75: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138357
CPU: Intel Pentium G620: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116399
RAM: G.SKILL Sniper 8GB (2 x 4GB) 240-Pin DDR3: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231417
I'm running Ubuntu on the server and have 3x3TB HDD's in a Raid-Z pool that are working great. I also have an 80 gig system drive working great as well.
The problem I've run into, is that sometimes, when I reboot the system, it shutsdown properly and actually begins the boot, but after giving 1 beep from the BIOS (signifying successful POST) and seeing the BIOS splash screen, it will just instantly kill power and shutoff. It seems to do this after successful POST, but before beginning to boot the OS. Also, it doesn't do this everytime, just randomly during reboots. It has never happend during a normal startup (from the poweroff state). Is there any way to troubleshoot this problem?
