My cd-rom stopped working, so I bought a new one. but after I installed it, the computer can't boot up in one try, I have to restart my computer every time and choose 1 normal on the menu to get into my windows every time now. but if I put the original Cd-rom back into the computer, it boots up fine, so basically, the computer won't work with any other CD-roms, what do I do? help!!!!!
