Just like the title says, my DVD-rom drive is intermittent. I just reloaded windows due to a virus, and reformatted. When I restart, 90% of the time, the drive doesnt show up under My Computer. And if I insert a cd or dvd, it just spins up for a second, then quits and then nothing. I try restarting all the time, and if I insert a windows cd, sometimes it doesnt autostart the "windows set up". What's going on that's causing it to only see it a few times out of many? The drive is brand new, and used probably 10 times until reformat.

Thanks in advance.
