My cd drive will read cds but not dvds i try to istall somethig it wont work
while the other two posters have pointed out the obvious, that CDROM drives only read CDs, and that you need a DVD drive to read DVDs, i would like to add something to this.
I will asume you have a CDROM COMBO Drive, that *should* play CDRs and DVDs.
if you find it does spin CDs up and read them, but not DVDs then i might be able to offer some suggestions.
firstly, make sure there is no software conflicts (like two CD Writing softwares trying to use the CD Drive at the same time.. ). you shouldnt have to worry about drivers for the CDROM, as the default OS ones should suffice. but they may be corrupt. you could goto Device Manager if you are on Windows, and uninstall and reinstall the driver for the CDROM. it should find it automatically in the install wizard.
ok at this point i don't see how software could cause any other issue , so we should look at it being a hardware issue:
if you have the ability, try changing the IDE Ribbon Cable that connects the CDROM to the Motherboard. if that doesnt work, try changing which plug in the IDE cable the CDROM plugs into. these plugs usually have a blue plug at one end (motherboard end), and there is two plugs at the other end, or master and slave. keep the jumper pin on the CDROM set to Cable Select, so you dont need to change it to slave, when its plugged into the slave port, or master pin if set to the master port.
finally, if none of that helps (and it probably won't ) you might find that the actual fault is due to the laser in the CDROM not focusing tightly enough and therefore cannot read the data on a DVD ROM because of this. the only way to tell if this is ok or not, is to plug it into another computer and see if it can read DVDs.
you might just be better off spending 20-50$ and buying a new CDROM Combo drive from your local computer hardware store.
