Can anyone offer any advice?

I run under XP.

Quite regularly my system reboots itself when the CD/DVD tray closes.

Could there be a software problem or is it more likely a loose connection?

Thank you

Sways

When exactly does it restart? At which part of the insert sequence does it
do so?

Press button > tray ejects > insert CD > push tray/push button > tray closes
> tries to read > stops reading ???


Also:


Check your Event Viewer via Administrative Tools.

Open the System as well as Application tabs and look for red X errors that coincide with your problem. Details here:

Basic information on Event Viewer errors can be found here: EventID.Net




Also turn off the auto restart function:


How to turn off Auto Restart in XP

Right click on My Computer

Select Properties

Select the Advanced tab then the Startup & Recovery section

Select the Settings button

Uncheck "Automatically restart" and then click Apply


This will give you a Blue Screen with the error message rather than restarting the computer.

Write down the error detail then use the reset button on the computer to restart.

The system reboots just as the cd tray finishes closing, I guess the system is just aware that it is there.

A few times when the cd tray has been open, I have removed a cd and am looking for another to insert, the tray has automatically closed without me touching it and the system rebooted.

See if turning off auto restart throws any errors.

If not I would open it up and reseat all the connectors at the drive as well as the motherboard.

Also perhaps try a different molex connection.

Thanks for the advice

No problem. Let us know how it goes.
