....changing the DVD-RW drive to "Master" as DVD drives prefer the master setting. You can leave the CD-RW drive set tp CS or slave. (Personally, I prefer slave.)
My desktop keeps freezing after booting up. The keyboard and mouse will work for a minute and then nothing. The screen freezes, the mouse is the sand thingy (I can't remember I am so mad). I just installed a new DVD burner, I made sure both my DVDRW and CDRW were set to CSelect, they are connected, they light up when I power on the tower. I get a message that the "Secondary Drive 1 not found". I followed the instructions someone gave me on clearing the NVRAM. And now it is worse??? HELP me please!!!
