Computer will not shut off with PCI card installed

[i430VX]

Hey guys, I’m now the proud owner of a PCI 8400GS that I got for my Compaq DeskPro EN running Windows XP.

There’s just one small issue. With this PCI GPU in, the computer will not shut off. Doesn’t matter if I boot windows or not, and it happens in other computers that I’ve tried the card in, too. It does “flick” off for a split second but promptly turns back on and begins booting again.

My questions are:

-Why does this happen?

-Is there anything I can do to stop it, like taping over a specific “power on” pin or something?

thanks,

i430VX

See if there are any wake options you can disable in the BIOS.

took me a bit to find the thread again, it got put in a better place i see.
Yeah, after several minutes of searching in the BIOS i finally found a setting for PME events, set it to disabled, and sure enough it stayed off. Still sorta weird that it did that in the first place, but whatever.

Thank you for the help!
