I am not sure what the problem is but i have an Error Code 31 with my Lite-On LTN486S internal cd-rom drive. I can see it in device manager but my pc does not recognize it in my computer. It opens/closes drive tray but that is it. I have a Dell Optiplex GX400 running Windows 2000 Pro. Service Pack 4. Any help would be greatly appreciated. Oh and i can't reinstall windows, I do not have Windows Disk.

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
Uninstall and reinstall the driver
Uninstall the driver from Device Manager, and then scan for new hardware to install the driver again.
You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.
On the device Properties dialog box, click the Driver tab, and then click Uninstall. Follow the instructions.

Open Device Manager, click Action, and then click Scan for hardware changes. Follow the instructions.
first uninstall the drivers of CD-ROM and then again install the drivers you will see that it will play your CD. If it doesn't play then check your CD-ROM jumper settings remove the pin and set it to slave mode.
It should say on the label, but if not, you can multiply volts times amps to get the wattage.The power supply for these puts out 2 voltages (12V and 5V), so use 12 V to get a more accurate figure.See if your label has volts and amps listed, then multiply these to get wattage. Watt=Volt X Amp.
