PC/104 TITAN SBC Board power cycle issue

We have been using VIPER boards from now Eurotech in our product lines. 
They have been running basically pretty well.  However, Eurotech
discontinues making VIPER boards and came up with TITAN boards as an
alternatives.  

In our past year experience using TITAN boards, it happens quite a few time
that the board dies right after power cycle. That is, when we power cycle
the chassis where TITAN board sits, sometime the boards won't boot up and
never will.

Just wonder if any of you using TITAN boards have similar experience and if
you have a clue as to what happens.  We have no clue whether it is board's
problem or hardware design issue (with the mother board) or even, in a
remote chance, software causes the problem.  By the way, Windows CE 5.0 is
the operating system running on our TITAN boards.

I'd appreciate any feedback from you.

Could the new board be stressing your power supply? Perhaps you are on
the 'edge' of the low-power reset/watchdog circuit's threshold.
Has anything else changed in the system?
I'm more comfortable with hardware from winsystems.com , but almost
anyone could 'upgrade' and overlook power issues. Perhaps contact
Viper to see if they have updated bios as well.

good luck

Thanks for your replying.  Talked to the hardware engineer; he didn't think
it wsa the case (low-powers supply.)  On one hand, when this happens, the
board seems to be fried.  CPU is pretty hot.  On the other hand,  Eurotech
has warned not to use PC-104 to power the TITAN board and we have provided
5v power cable to the board without cutting the 5 volt connection in
PC-104, which makes wonder if, at one instance of powering-up, the board is
powered by PC-104 alone without the 5-volt supply, for some reason.

Thanks again.

Perhaps Eurotech would be willing to examine a system , if you can
send them one, to look for voltage spikes/race conditions/ w'ever.

anyway - good luck
