Hello. I just built my first custom pc, and I have run into a problem. When I installed my lite-on dvd-rw LH-20A1L it is not recongnized by my computer. I can still burn cds dvs, and I can still use it in every way a recognized drive would, but the safely remove hardware icon on my system tray has this drive listed. I stupidly bought this product OEM (I didn't know what that meant at the time), so I don't have the install disk. So, how do I get this drive recognized by my pc??? Also, when I put a disk in my lite-on drive it doesn't autorun. I have to go to mycomputer and select the icon for the cd to run. I don't know if this is because my computer doesn't recognize the drive, but even when i load an iso onto a virtual drive it doesn't autoload. So, how can i set my computer to autoload a disk???
