Ok, I just finished building my custom pc. The stats are: Asus A8N sli premum mobo, AMD Athlon 64 3200+, 160 gb seagate sata 3gbs hardrive, 400W power supply, 512 mb kingstom ram, e-GeForce 6800 GT PCI-E video card, and NEC dvd-burner. <p> The problem is that I cannot get any drives to boot from the IDE channels. I'm only using the IDE for the dvd-burner optical drive. I tried changing the cables, changing jumper settings and nothing! The optical drive is working because I already tested it in a friends computer. The hardrive is using SATA1.<p> When I turn on my computer it just lists all of the devices detected, not showing anything on the IDE channels...it just shows this message: <br> Disk boot Failure insert system disk and press enter<br> Is this message normal? I assume that message is asking to insert the OS disc, but I can't because of this problem<p> If I get one of those IDE to SATA adaptors for my optical drive, would it recognize it? What can I try to change in the BIOS so it can recognize my dvd-burner?<p> I can access the mobo BIOS. The cpu seems to be running fine, I already tried changing the ram to a different channel. Also the computer did shut itself down like 3 times since I installed it, is using a cheap 20 pin PSU that came with the case, whereas, the mobo is 24 pin, but I can still power on because of the extra 4 pin connector. Could this cheap PSU relate to my problem of not recognizing drives in the IDE channel? Or is it motherboard?<p> Please help!
