I have a liteon LTD-165H dvd rom which will not open anymore. I had to take back my graphics card after it stopped working and when I brought home the replacement the computer shop gave me while my card is being sent back to the manufacturer I discovered that my dvd rom will not open. The green light still flashes when I press the open button but then it stops and the dvd rom stays closed. Is there anything I can do to get the dvd rom to open??
