Hi to all of u guys on the forum. I fanally managed to install Snow, and everything seemingly worked flawlessly. However, i have a problem with my Liteon dvd burner. When i start snow it works fine, and i can eject as many times as i want, paly dvd an cd-s.... all normal. But if i leave my computer for a while at idle or am doing something else, dvd rom would get stuck. If i try to eject it, i get a ball spinning endlessly on desktop... So dvd simply disconnects and vanishes vanishes if it doesnt do anything, as if somebody pulled the sata cable out of the case. Any ideas guys, please?!

Simple restart doesnt unlock the drive. When i try ordinary restart, AHci bios screen halts because it can not list the drive....I have to turn off the pc and turn it on in order to get it unstuck.
Any ideas are greatly appreciated!!!!!
