How do i get my computer to work?

My cd-rom wont work. the computer says that it causes the system to be unstable. how to i get it to work?

• the red light on the front of my tower is on (i think it used to be green), so i think the stuff is all still connected on the inside, though i havent opened it up to check. I was thinking it might be an ugly virus of some sort, but i dont know. also, as i mentioned, everytime i start up the computer an official looking bubble pops up on the bottom left saying 'your cd drive has been disabled because it causes the system to become unstable.' so...i think that is a big clue. When i click on the bubble for more info it just sends me to the cd-rom makers website and theyre just like 'gimme money for updates!!!!' so thats no help. any ideas? oh, and i dont think i mentioned this earlier, but the cd-rom -will not- open.

  Problems reading and writing CDs are common. In many cases, the problem cn be solved by checking the PC with free software, hardware modifications and cleaning the CD drive. I found the information at http://fixit.in/cdrdrive.html useful.
