What was the old CPU? New CPU?
Is DVD drive recognized in system BIOS?
DVD drive is "not recognized" where?
Try downloading latest system BIOS version from computer mfg. If a home-built system, download latest BIOS version from motherboard mfg.
I recently changed processors - nothing too technical -except now 5 times out of 6 , my PC will not recognize my DVD drive.There was no problem before.
Any ideas please??? (Windows XP SP2)
