CD/DVD Rom Error Code 39.

[Chintam]

hi there......

My Windows Operating System cannot load the device driver for this hardware. The driver may be corrupted or missing. and it is showing Error Code 39.

Due to this error my cd/dvd drive does not display up in MY COMPUTER and it's entry in DEVICE MANAGER has a yellow exclamation mark near to it.

I have uninstalled the drive in DEVICE MANAGER and rebooted but still the same error code.

I would be really grateful if anyone could tell me what this actually does and whether how to resolve this conflict.

any reply would be greatly appreciated!
