The hang/freeze after BIOS entry splash is most likely the Motherboard having problems finding drivers for the attached devices. It is best to use only the onboard devices and minimal devices to get the MoBo started.
I would start by loading the BIOS default CMOS settings and then select the SATA controller based on the config you want <RAID> or <AHCI>
Do not disable UEFI
Use only the internal Blue 6.0Gb/s (ports 0&1) or Black 3.0Gb/s (ports 2-5 SATA connectors for the HDDs and Optical drives.. The Grays are secondary SATA ports.
If you are using the PS/2 port it is only for 1 device (no 2-1 "Y" cables) [only KB or Mouse] and most USB Keyboards will not work with a passive USB/PS/2 dongle. [been there done that got the Tee shirt]
Thank you guys for your responses.
I ended up testing the MB outside of the case with a different power supply and then again with the current power supply and found that the build was working and able to boot from other devices. It seems as though the CPU isn't being powered on while I have it installed within the case.
So it seems to me that there is probably a short occurring from the board to the case. Is there anything else you guys could think of that might be the issue?
