[Pc_Support] using DVD drive shuts down computer

[Justin M. Keyes]

Hi Friends,

Whenever I try to use the DVD+/-RW drive [1], the computer turns off
immediately. I suspect it is a power supply [2] problem, but read on
please...

To test, I left a CD in the drive so that it would spin up when I
tried to boot. I disconnected the hard drive, the graphics card, and
the floppy. So, the power supply is only powering the DVD and the
motherboard. Booted the computer, and when the DVD spins up the
computer turns off. Same result when I tried different Molex
connectors with the DVD drive.

Why would the power supply suddenly start hating the DVD drive? Could
the DVD drive itself have messed up the power supply somehow?

I replaced the power supply with an old Antec power supply, and
everything ran OK, however, when I used the DVD drive, the Antec
started making weird crackling/static noise, so I disconnected the DVD
drive for fear of ruining another power supply. The Antec ps still
makes "static" sounds, but not as bad as when it was using that DVD
drive.

Is it possible for the DVD drive to harm the power supply?

Thanks very much...
