My computer after some time keeps disabling my CD disk drive. I get a little icon in the tray that says disabled and when I look in explorer, it isn't there.

When i look into it further, there is this error message:-

"Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)"

To get my drive back, I have to restart the computer.

Any ideas what to do? Never had this problem until about five days ago.

Any help appreciated.
