Well I know it shouldn't be the bios as I haven't been able to get to it. I
know its not the video as I am using the on board video at this point. The
ram can only go in one way so I will rule that out. What is meant by
motherboard not seated right?

I was guessing that you installed a motherboard in a case yourself - if
you installed it and shorted out a circuit (electrical trace on the
board) with a stand-off / screw, or if you over-torqued the screws, you
may have a bad motherboard.

If the unit won't post, and you get some LED's for a flash, and no beeps
(connect the PC speaker to test), then you either have bad RAM, bad CPU,
bad power, or a bad motherboard (since the video is built-into the
board).

If you check the stand-offs / screws, and none are in the wrong
position, take the computer to a shop and have them test it.

One last thing, if you have two sticks of RAM, and your board supports
booting with just one, try it with just one.

Steve:-
If I understand correctly you say that you get momentary power to the fans
and the LEDs and then nothing.
Unplugging and replugging the power cable to the case repeats this.

If this is correct then you still haven't pushed the power button on your
case after plugging in the power cable.

It can also be shorted Reset switch or Power switch.

Sorry I missed telling a step. If I press the power switch, the led
flashes, the fans go for a second and then nothing. If I press the power
again nothing happens until I unplug and replug the power cord in and then
when I hit the power again it happens again.

I did install myself. It is the 10th time I have built from scratch. Last
ngiht I checked further and decided it was best to take into local shop as
there can be too many variables that I don't have time or resourses to
check. Thanks for the help.

I thought it might a shorted switch. As I do not have a alternate case or
powere supply to play with I decided it would be best to admit defeat and
get the local shop I bought it from to deal with it.
