Hello everyone, firstly here are the specs.

Board: ASRock X58 extreme
CPU: Intel i7 975
GAC: EVGA GeForce GTX 275
Ram: 3x 2GB DDR3 Cosair Doiminator
Power: Cosair TX750w
OS: XP (64 bit)

Today I attempted to install an internal blue ray drive on to this system. After installation of the sata power and sata data cables to the drive and firing it up the board stops at the boot screen. Showing 78 on the Debug LED which according to the MOBO manual states, "Initializes IPL devices controlled by BIOS and option ROMs."

My troubleshooting thus far;

1- disconnect blu ray drive and external HD's
-still gives error
2-disconnect all drives except windows installed HD and attempt to boot in safe mode
-boot process stops at acpitabl.dat for over 10 mins but did boot to safe

I am up in safe mode (takes about 25 mins to get to) Where do I go from here?

Thanks in advance for your knowledge and contribution to my thread. If you need me to provide any more information please let me know and I will do my best to acquire it.
