I have had my computer for about 3 months, i built it with some new parts + some older parts. The old CD -rw drive I have came from a gateway computer . It is a model HL-DT-ST CD-RW GCE-8160B. I think it is made by LG, but that's not for sure. From the day i started using it up until a week ago, it worked fine, I was reading + writing discs all the time, no problems. Then, The cmputer stopped recognizing the CD-rw and it disappeared from the my computer fold. I went to the device manager + it says this: "Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41) Click Troubleshoot to start the troubleshooter for this device." I tryed the troubleshooter but it didn't help. I really need help + I hope I can attain it here. Thanks in advance.
