I have been having a problem with the Crosshair motherboard- the BIOS has been able to run twice on two different days- when it is up it sees my drives, processor, I can set settings - everything loks great but when I save and exit I am left with a light show, the fans running, the hddr warming up, the dvdrw flashes for about 8 seconds and then goes off. The last time the BIOS came up, I had turned the PC on/off several times, pressed the delete key several times, checked on other tasks and then about ten minutes later, out of the blue, I heard a post, the monitor turned on, and I entered BIOS.
I have installed an AMD ATHLON 64X2 +6000, GEFORCE 7600 GT, a 160gb PATA drive, 500gb SATA, 4 gb ddr2 800mghz RAM , 600W PSU, AND A dvdrw. I finally have the dvdrw configured as the only IDE device, and the SATA as the only hddr. The short and sweet is the BIOS runs sporadically and I can't get the dvdrw to function so I can load an os. Any help or suggestions I will greatly appreciate.
