I have recently installed a new firewire card on my pc, I run on XP Pro., I've had the card to work great, but I :( have to turn off the pc manually, I select turn-off, and it does, in all fairness turn off, but as it does so, so it powers up again !!
It has only happened after installing the new ieee1394 card.
By m/b is reletively knew, I installed a Gigabyte GA-7VA some 6 months ago.
