I've just finished assembling a new system. When I try to turn it on the fans
get power for less than 1/2 second, then shutdown.
Nothing else happens.
The case, CPU, power supply, and GPU fan all start, then immediately stop. To
make it do even that again I have to hold the power on switch for 5 seconds,
let off, the push it again. Or shut off the power supply switch long enough for
the green led on the motherboard to go out. I've taken the whole thing apart
and reassembled, then double checked all connections again. No change. any
guess what the problem is. My only thought is the power supply itself because
it doesn't power up long enough to be much else. System specs..
Antec SLK3700-BQE w/350 watt PS
Asus P4P 800 MB
XFX FX5200 personal cinema graphics
TDK 440 N DVD burner
P4-3.0
2@ 512mb Kingston PC4000
Seagate 80 MB HD
I've tried with only the apg card, CPU and fan, HD, and one stick of ram
installed. No change. TIA

The symptom you describe sounds like something shorting out the power
supply, or it being overloaded, and any defective component can do that:
motherboard, processor, display card, hard drive, CD, etc.
If it's new equipment, though, odds are that something is connected wrong
or you have a short from the motherboard to the case (such as not having
the mounting stand-offs in the right place or using oversized screws where
the head contacts a circuit trace).
Try disconnecting the floppy. People sometimes get the power connector off
center, or even upside down, and that'll short the PSU real easy.
And, speaking of disconnecting things, you can't get power to even stay ON
so forget about 'booting' for the moment and try removing EVERY thing (no
nuttin; just the motherboard) and see if you can get past it not shorting
out. If that still doesn't stay on, remove the motherboard, put it on a
piece of cardboard (so there's nothing for it to short out to), and try
powering it up naked.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: new build problems |

Two thoughts, try setting the m/b in the cardboard box or something other
than the case, you may have one of the set pins grounding out the board.
Second thought is a bad p/s; when I rebuild my son's system, new
m/b-processor-ram-vid, into a working case and p/s, nothing would work,
tried second working p/s-nothing. Was just about to send m/b back and tried
in an old system lying in the basement and it fired right up.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: new build problems |

I'll try unhooking everything, then removing the MB from the case. I used only
the standoffs and mounting screws provided with the case. Also the MB manual
shows where to place screws, 9 total, leaving one hole open near the PCI slots
so that's how i did it. there was only 9 stanoffs with the case. Thanks!

Just off hand I'd guess it's 350 Watts since he said it was a 350 Watt PS.

Well, i started with MB out of the case with nothing but the wires from the PS
plugged in and finished with CPU, RAM, and video card plugged in. No change.
1/2 a second or less and things get quiet. Any other thoughts? Buy a new PS and
see what happens? Buy a Dell? LOL
thanks,
Scott

Well, yes and no. Take out the memory, CPU, and display card, I.E. "no
nuttin," and see if powers stays on. ('No' because that's what I originally
said. I.E. how do you know THEY are good? Which, btw, also means none of
those cute little wires to the front panel LEDs and such; just the power
switch; and I'd try tickling the power-on pins with paper clip instead of
the power switch just in case IT is 'stuck' or defective.)
The 'poor mans' PSU test is to put only a known good hard drive on it (no
motherboard or anything else) and jumper the power-on wire with an
appropriately 'U' shaped bent paper clip inserted into the motherboard
connector pins (14 to 16).
<a style='text-decoration: underline;' href="http://xtronics.com/reference/atx_pinout.htm" target="_blank">http://xtronics.com/reference/atx_pinout.htm</a>
In particular, the green wire (14) to either of the black grounds on pins
13, 15, 16, or 17. 14 to 16 is a good choice.

Tried all that, nothing. Got a RMA #. Sending back just the power supply,
Mwave said no need to send the whole case back. Here i bought an Antec case
thinking i would avoid problems.........
