I have a Dell 4100 with Adaptec CD software which has a CDRW and a CDROM-DVD. The DCROM-DVD will no longer read CDs that I have burned. It use to do this just fine, now the light blinks but it never seems to find the CD and while it's doing this the computer becomes brain dead. Some times it will give up and give me back the computer but mainly I have to reboot. Both drives have also developed a problem with ejecting CDs. this also sometimes requires a reboot to get the CD ejected. I have tried the burned CD on other drives and it works fine. Any help would be appreciated
