I thought I've seen everything until...

A computer came in that would shut down and reboot whenever a CD was put in the drive.  Fun times!  It even did it with the IDE cable unplugged.  It worked with a test unit though.  It must've been something in the motor of the CD drive that caused some sort of surge in the power supply.  Anyone have that happen to them before?

Surge or sag in the +12VDC supply rail (ATX spec:  11.4VDC to 12.6VDC).

Would you also recommend a power supply replacement?

[Computer_Commando]

No.  Seems like PSU and/or motherboard are doing exactly as they were designed to do.  Replace the CD drive.

I've done that already, but thank you for the advice.  I was just wondering if it was possible if the power supply was also compromised by the drive error and you have answered my question.
