Hey, I am having a problem with my CD/DVD ROM drive. It will not read certain games. For instance I have installed Flight Simulator in the past but then uninstalled it. Now I want to re-install the game, but it does not let me. I have tried all of the disks #1 #2 and the Acceleration pack (all installed before, then I uninstalled them...) I put the disk in the tray, then close the tray and wait but it does not registrar the disk, it does not even acknowledge that there is a disk in the drive. Now the weird things are, that I can hear the disk spinning and see the LED flash. Then also on the screen I see that is trying to load the cd, but it does not. I go into My Computer and look and try to open the disk and it tells me to insert a disk and then ejects the drive. I know the disk drive works because I installed a game (Tom Clancy's HAWX) and that works fine. I can play Crysis with the disk. I can also play a DVD movie and it will work fine. I have also tried putting in ARMA (Game for Windows) but that does not registrar. It does the same thing as FSX (Flight Simulator X). I have also had this game installed before and then uninstalled it. This is just weird to me, it also seems like it is just games that I Have installed before then uninstalled that appears to being doing this. If any one could help that would be great (IMPORTANT INFO BELOW): The Night before this started to happen I upgraded my PC UPGRADES INCLUDING: -Intel Core i7 920 @ 2.67 Ghz -MOBO: EVGA x58 -GPU: EVGA GTX 260 -RAM: G.SKILL 6GB DDR3 @133 Mhz Components that stayed the same: -500GB Seagate HDD -Rosewill 750 PSU -Zalman 9800m CPU fan -CASE coolermaster -CD/DVD drive: (It can read DVDS and CDs also write them.)See below: -http://www.newegg.com/Product/Product.aspx?Item=N82E16827106072 -Vista Ultimate SP1 32 bit Things I have tried to do: -Re seat the cords to the Drive -Update Drivers (There where no updates) -Make sure the drivers are working (They were) -Look all over the place for any settings I could change (could not find any...) I have no idea what the problem is or what is causing it. It might be Vista with some stupid software protection thing. It could also be a hardware problem. I don't know, I am stumped on this one. If some one could help me and maybe others that have the same problem that would would be really nice Thank you! Also if you need any more information I will be happy to give it to you!
