I bought the asus A7N8X deluxe and an Athlon xp 2600+ thoroughbred about 6 months ago and they worked fine until 3 weeks ago. At first it stoped recognizing my cdrw intermitantly, then all together. and of course my slave DVD drive failed to recognize. I've checked both drives and both work fine in my other system for hours on end. and my DVD (but not the cdrw) will run fine as master ide 2, but not as slave IDE 1 "80 conductor IDE cable not installed". I've reset my bios and both worked fine as master/slave (in any order) for about 1 hour and then it started doing it over again, without any change to the bios settings. i've checked my power supply and changed IDE cables, no help. asus tech support just gives me the run around...help!
