Power supply?
 

I was sittin' my kitchen listening to streaming-audio and all of a sudden I
heard a click and my computer died; not a slow death, but an absolute
instant-death! Everything connected to the power supply: fans, case lights,
etc., are all dead! Is it safe to assume that the power supply went south?
I suppose not, since when I first put it together, nothing would come on
because of a bad memory-stick. The power supply is an Antec power supply
that came with my Antec case, are these generally good power supplies?
There's no user-replaceable fuse, should I look for this in a replacement,
if it is indeed the power supply? Thoughts?

Thanks in advance!

No. Disconnect items one at a time (starting with drives), and check
for PSU operation after each. If the PSU still won't start, test the PSU.

To test an ATX PSU:

First, disconnect everything from the power supply (including MB.) Plug
AC cord into the rear of the PS. IF the PS has its own rocker on/off
switch, turn it ON. There should be +5v on pin 9 of the 20 pin connector
(+5vsb, usually a violet wire.) There should be 0.8v on pin 14 (PS-ON,
usually a green wire.) This is from an internal pull-up to the +5vsb.

Connect PS power leads to 1 or 2 IDE HDs (for a load). Jumper pin 14
(PS-ON) to pin 13 (ground, black wire.) At this point, fan in PS should
start spinning, drives should spin, and + 5/12v, -5/12v, +3.3v, and
+5vsb should be present at 20 pin connector.

Disconnecting pin 14-13 jumper should turn supply back off.

Further, if the PSU starts:

When your system fails to start, what is the voltage on pin 9? If it is
less than 4.75v, either a) the logic on your motherboard is shorting
b) your +5vsb is under powered, or c) your PS is bad. It is
most likely a combination of b) and c).

If your +5vsb is OK, measure pin 14 of the PS/MB connector. If it is 0.8v
(and the +5vsb is OK), the power supply should be on. If pin 14 is 0.8v,
the +5vsb is OK, and the PS is OFF, the PS is bad. If pin 14 is 2.0v, the
power supply is being told to stay OFF by the MB. If depressing the front
panel ON/OFF switch does NOT lower pin 14 to 0.8v (and the +5vsb is OK),
then the problem is NOT the power supply, but rather MB related.

Thank you! I will print your reply and do the step by step checks, it
sounds like a hassle, but I suppose there's no other way, unless I just take
it somewhere and say: "fix it" Thanks again!
