You could try this: Uninstall the U3S6 from Device Manager, shut down, remove it from the computer. Then reboot and go into Windows. Check that the monitors are working and everything is cool in Device Manager.

Then shut down and install the U3S6 in a different x4 slot if you have one (or a x8 or x16). Restart Windows, install the driver, and test.

The reason for this is that some cards attempt to use certain system resources depending on where in the PCI bus they are installed on some systems. There are of course ways to change the IRQs and resources from the BIOS or even the OS, but this test will tell you if this is the cause or if it is something more to do with the card itself or it's driver.
Hey man,
Thanks for the answer.
Everything is definitely cool without the U3S6, whether out of the compu or disabled in bios.
Unfortunately I don't have another x4 slot, or anything which could handle the U3S6.
I can use the U3S6, only the primary monitor then does not function. In that setup, no error/conflict shows up in device manager, haven't compared IRQ's for everything, though. You think I should?

Yes, it's the only thing I can think of that would explain your symptoms.

You should take some time to read up on "changing IRQs" before actually changing settings. If you have a modern motherboard it will use "Advanced PIC" or APIC for IRQ's.

Jan, is the XP install on a different PC or are you dual booting it with Win7? The ASUS page TVeblen referred to does not have your listed mother board in the compatible U3S6 list.

It's precisely the same machine (dual booting). For compatibility listing, you're right. My mobo is not on the c list for U3S6. Haven't found out what the incompatibility would consist of, though...

So my best guess is either an obscure IRQ / other resource conflict (does not show up in device manager) or, more likely, a dual / sli gpu connected phenomenon which did not (yet) exist in XP, but does exist in win 7.

The logic would be: there's a card/device in sli position, let's find out if it does graphics and ask whether the primary monitor is attached, query goes wrong, primary monitor no longer available, secondary used for login, everything works except one monitor.
On XP, no questions asked, ok, everything works.

Not too advanced thinking on my part, but still, sounds logical to me.

A strange test perhaps.... You state that your main monitor does not function correctly in W7 with that card in. It wont go past BIOS. Have you tried booting in Safe mode with th card in? I know your second monitor won't show... But it would be interesting to see if basic Safe mode W7 drivers do let the monitor and card combine....

It's a good thing to test - didn't yet try.
I'll try that tomorrow (getting late here anyway) when the calculations I'm running right now are finished.
thanks,

Yep... Probably just as late as it is here
Hope the test tells us something tomorrow!

The pics for ASUS shows the U3S6 needs to be in the 3rd X8/X16 slot, that may be the issue, since your board has but two PCIeX8 slots? Doesn't explain why all is well in XP though.

You might evaluate the Different BIOSES. they mostly refer to adding CPU support, which may have something to do with the way Win 7 handles the U3S6 card. Just be aware flashing your BIOS can render your Pc unuseable if you don't know what you're doing. Proceed carefully, you seem techie enough to handle this though.

Tried it, they do combine in safe mode. The USB 3.0 Host Controller utility recognises the card and the primary monitor keeps working.

Flashed the bios to the very latest, too (was asus 5001, a bÍta, now 1103).

After normal boot, no change though.

I'll check again for the latest Nvidia gpu driver, did the last one like a month ago.

Still a puzzle to me..
