DTK DEFT-865G Barebones

[Jav Atar]

Hello,

I bought one of these, and it seems to have arrived DOA. I installed
the CPU and memory, and hooked up a monitor and power, just to test
the boot function.

When I power the machine on, it does nothing. No beeps, no fans,
nothing at all.

Any hints or comments most appreciated!

Cheers,
Jav Atar

make sure ALL the power connectors are secured properly
barebones?.... A bare bones system 'to me', is an assembled case, mainboard,
cpu and memory- tested and shipped.

I don't know the brand, if it is some cheap Chinese brand check the
voltage selector switch, assuming you didn't already. I have seen cheap
Chinese crap on the web that 120 Volts and 60 Hertz are both optional
(UPS Etc.)

Are you certain the Power_BTN wires are connected to the correct
header pins on J1 System Panel Connector ?

I don't see a LED on the motherboard, for monitoring +5VSB. Power
comes in two stages. When you plug in a ATX power supply, with
the switch off on the back, there is no power output. In this
state, with the switch off, it would be safe to add or remove
components on the computer. (But I recommend always unplugging
the computer, just to be safe, before touching the hardware inside
the computer.)

When you flip the switch on the back of the computer, the power
supply delivers the +5VSB. That powers the circuitry used to
turn on the computer later. Some motherboards have a glowing
green LED to warn you that +5VSB is present, and that it is
unsafe to add/remove hardware.

When you push the power switch on the front of the unit, the
motherboard converts the momentary front power switch contact,
to a steady command for power on the PS_ON# signal, on the
main 20pin ATX power connector. The power supply should
respond by spinning its own fan, and sending out the regular
high current 3.3V, 5V, 12V and the motherboard begins to POST.
That is how it is supposed to work.

What cpu? .... I surprised the hell out of myself when i found out i had a
socket 478 cpu in a socket 478 that wasn't acceptable!
machine would not boot at all or just fans if incorrect.
be sure.865 takes most any if bios is correct and flashed to do so.

In which case, Jav should tell us what the SSPEC number, or the
order code is, that is printed on the box the processor came
in. The SSPEC is a number like SLxxx, where the xxx indicates
the processor. The order code is a longer string of characters.
Using that info, it is possible to look up the processor's
vital statistics, on the processorfinder.intel.com website.

Hello Paul and Others who Appended,

I checked into these things. As far as I an tell, this mobo does not
have a LED. As someone suggested this system seems to be cheap far
east stuff.

In any case there is no activity in the system. No fans turn, in the
power supply or otherwise. I verified the on/off switch was correctly
connected, so that was not it.

In the end, I requested the seller to allow me to return the unit. So
it will be on its way back today.

I don't know if this is the case with regular size PC's, but in this
small XPC category, you really get what you pay for. I have built 3
other XPC's, two by Shuttle, and one by a another no name brand. The
Shuttle PC's seems to be very stable and worked first time .. the
other PC's, including this 4th DOA unit .. well ..

Anyway, thanks for all your help!
