I installed a new pci board (2xFireWire External + 3xUSB2 External + 2xInt PCI, A-329 is code number)into PC(F-S Scaleo 600)in PCI slot 2. Since then it will not do a power off at shutdown, just reboots itself. I've checked all network connections are disconnected or disabled, and also gone into BIOS to make sure there's no "wake-up" parameters set. Anyone got any clues?
changing the slot probable won't make a difference - - -but it takes ' a dodgy slot' out of the equation. And not powering off, does that mean your screen displays the "windows is shutting down" thingy or it tells you it has shutdown and to power off you have to hit the power on/off button ? And does it boot up cleanly after such occurences or do you need to run scandisc - - the latter signifying that your PC didn't closedown correctly.
As it's XP when you "turn off" it auto powers down (or at least it did). It now goes to the "No Signal" on the screen (where I can power off the whole thing), but if I dont get the switch it reboots cleanly. No scandisk here (thank goodness). Thanks for your help so far, but no solution yet.
XP treats Firewire as a networking protocol (which it is). It may be that you have an entry in your BIOS that has enabled the 'wake on LAN' facility, triggered by residual activity in the Firewire card.
Try disabling the 'wake on LAN' setting in the BIOS.
I've now gone through all the BIOS again, I can't find any "wake on LAN" setting, all power settings are disabled. I've reinstalled the drivers (in desperation more than anything else) and am now attempting to contact the makers (InnoVISION)...I'll put up the outcome of that. Thanks for assistance.
My Bios (Asus) has a Power Up Control menu which includes a range of things which will power up the computer - including Power Up on PCI Device. I had a similar problem recently when I tried to enable Wake Up on Lan while using a Wireless PCI card. I know it's a longshot and you've probably had a good look at your Bios options, but it might be worth another look through.
