Hi Tech folks! I have problem with my DVD ROM not being able to run after I had clean my compt. It was showing in the device manager with the yellow exclamation mark stating that dvd driver is missing or corrupted. I had reinstalled the driver for the DVD from Toshiba website and it is still not working. Any idea what I should do? I am trying to get to the BIOS but not sure how to get it. is it F12? Anyone who had this same problem....plesae assist!!!
