Hello. I'm working with a new system I just built and at first I used an old acer 24x cd-rom, but then when I would put cds in the cd-rom, xp would ask me to put a disc in the cd-rom when there was a disc in there!, so last night i bought a new cd-rom (56x) and it worked for a couple of installs, but now this cd-rom is doing the exact same! Are they both bad cd-rom's or is there something screwed up on my system? Any help would be greatly appreciated. Thank you!
