Hi everyone ive recently built my first system and everything is running as should except the new SATA LG GH22NS50 dvd multi burner ( oem ).it burns discs , no problem, and it will read and install in dos. But within windows it becones unresponsive when reading and causes windows to "hang" and become unresponsive.ive updated the firmware,uninstalled the reinstalled dvd drive and tried changing sata connections, the motherboard chipset drivers and all other drivers are up to date,im at my wits end and would appreciate any help.The rest of the system runs superbly well and i only have probs when i want to install something from disc into windows.My system is: Asus M4a77t Motherboard, Amd phenom ii 565 black edition with an extra core unlocked running at 3.8 ghz per core. 8GB ( 4 X 2 ) Kingston Hyper blue 1600 Ram. 1 x 80 gb hard drive for operating system and 1 x 300 gb hard drive for software .Palit gts 450 Sonic Platinum Graphics card. Benq G2222 HDL monitor. 750 watt PSU. Windows 7 Ultimate. Software and Games run brilliant. Its just the dvd drive thats giving me a headache. ANY IDEAS ????
