Vista - Re: DVD drive causes computer to turn off

My first suspicion would that when the DVD turns on it overloads the power
supply which causes a total shutdown. First step would be to examine the
cabling to make sure it is properly connected, then try a different DVD
drive. Hopefully it is the drive as they are pretty inexpensive.

If it is still under warranty do try contacting Dell.

If you have not done so already, turn off the option to automatically
restart on system errors and see if there is a blue screen error that
explains what's happening.

have no appreciation how much those numbers report. Post those

In your case, important DC voltages are on any one of purple, red,
orange, and yellow wires where nylon connector attaches to the
motherboard. Simply press a probe in to touch each wire. Best
measured while system is accessing other peripherals (disk drive,
complex video graphic, downloading from the internet, etc
simultaneously).

What would be happening? Power supply controller (different from a
power supply but another component of the power supply 'system')
detects that an excessively low voltage has gone even lower. So it
sends a signal to the CPU to power off. You saw the rest. But nobody
knows until you first provide those numbers.

Nobody can identify this failure without a multimeter. A tool so
'complex' as to be sold in any store that also sells hammers. Wal-
Mart probably has a best price at less than $18. Or you can spend
days 'trying this and trying that' using wild speculation. Get the
meter. Have a definitive answer - no more speculation. IOW get an
answer from the few who actually know this stuff. But that will only
happen if you first provide those numbers.

Doors stick because of heat (expanding wood), humidity (also expanding
wood), too many coats of paint, loose hinges, loose screws in the door
frame, defective weather stripping etc. Yet you would have someone try to
"repair the foundation" first? You ARE nuts!

Most any door can be diagnosed by a careful visual inspection and utilizing
a 4 foot level.

Stick to "following the evidence" in your computer diagnosis - as you
describe it. Even then, a competent computer tech will have the problem
identified before you are done with all of your testing.
