Okay, There is no cd and dvd drives visible in my computer, or disk manager, or device manager. I deleted upper and lower filters in the registry and nothing happened. there are no exclaimations or question marks in the device manager and a search doesnt bring up the two drives. I tried making a windows xp boot disk that totalled six different disks but then it promted me at the end to begin setup of windows xp and i chose no, after running the six disks. still nothing has happened. I recently changed my motherboard and It may be slightly possible that i didnt connect the drives correctly if that is the case, what procedure should i follow for correcting the hardware issue. if thats not the case, what can i do to get the drives back? is there a program that creates drives that are real not virtual. any help is appreciated, thanks!
