Computer slow to boot after minor bios tweak.

[Capbadge]

Just bought a new Nvidia 8800 GTX Graphics card and fired it up for the first time a couple of days ago.
I got a higher 3Dmark '06 score with this single card than with my 2 X ATI XT1900XTX's in crossfire.
Trouble now though is that after making a minor BIOS tweak last night to disable the secondary PCIe slot, the machine now takes ages to POST and the score for my new Nvidia card has dropped to about a quarter of the first benchmark.
I have tried this now with the secondary slot enabled and disabled to no avail.
When I slot my ATI's back in, the PC runs as it should.
I haven't edited my signature yet but a brief summary of my Rig:
AMD FX60 @2.6ghz
DFI Lanparty CR-DF 200
2gb Samsung DDR
Polit Geforce 8800 GTX 768mb @ 1800mhz.
3Dmark '06 score : 9104.

You can try resetting your BIOS. That will reset everything to its default/origninal settings.

Thanks for that.
Just Re-flashed the motherboard BIOS.
(Went back to default settings).
Still the same problem.
It seems that the PC is slow only when this card is in.
The ATI's work fine.
But why was the card so good when I first put it in?

Do you have the most current drivers for the card?

I have the 64bit drivers that came with the card but they are really not an issue here.
The PC POST's very slow with this card inserted.
When I stick my ATI's in, the PC POST's normally as it did before.
