Machine boots up properly only on UPS and not on Mains

Hi,

On this particular machine I have both Debian & DragonflyBSD.
Debian hangs sometimes or goes for a reboot automatically but it does not
boot up properly when the system is on main power supply. The CPU fan goes
on in variable speed, on and off kind of perpetual rebooting with out
giving even BIOS display. It boots up properly if it is on the UPS alone (
when the switch to the main power supply is off )
DragonflyBSD does not hang or reboot automatically. So that is what I use
most of the time :-)
But if I reboot DragonflyBSD some times it hangs.
But if DragonflyBSD reboots without hanging then I have to switch off the
mains so that it will get power from the UPS to boot up properly.
If DragonflyBSD is on the mains the CPU fan goes on in variable speed, on
and off kind of perpetual rebooting with out giving even BIOS display just
like debian.
It boots up properly if it is on the UPS alone ( when the switch to the
main power supply is off )
I could get a coredump when DragonFlyBSD hangs if someone can tell me how.

Any idea why this is happening?

Thank you

Siju
