DVD rom won't run

Hi, I changed power supplies on my AcerPower SV computer running Windows XP when I tried to reinstall a game. To my surprised, the disk drive no longer runs. I tried Windows troubleshooter and it said that Windows loaded the software for the device but cannot find the device–Code 41. I know power is going to the drive as the power light goes on and I can hear the disk running for about 5 or 6 seconds. On the Device Manager, the DVD drive is highlighted yellow. When I tried to install another DVD drive, I got a Code 19 for the Samsung DVD-rom. Any suggestions? Johnny

My best guess is the cable(s) have been disturbed, it doesn't take much to upset them sometimes, could even be a faulty cable, more so if they are old, they really don't like being moved, so gently check the cables and try and make sure they are sat right without having to stretch round anything, or try another cable if possible, hope that helps.

Ok, I'll try that, every CD or DVD rom I install doesn't get recognized by the software. Johnny
