I have purchased new DVD drive and installed it after clean Intall win 7 64 bit ultimately , but unfortunately will not read dvd or cd.it still recognized by the machine. Double clicking the drive path in my computer will cause the drive to open.
I am not able to istall device drivers from motherboard cd
it is Sony nec optiarc ,model number ad - 7203S
My motherboard is Asus h81m-e
Asus Mainboard-DVDs should be bootable, did that work?
You can also try a different SATA-port for the drive, this mainboard have SATA2 and SATA3-ports
If not, teh drive is maybe defect or don´t like the mainboard
