Nvidia Quadro NVS 450 problems

I have an Nvidia Quadro NVS 450 video card for my 4 monitors, running on WinXP pro.
I have an Intel Core 2 Duo E4500 processor w/ 2g Ram.
I have a variety of problems and can't figure out if a card problem, SW conflicts or what.

When I bring the machine up in the morning, monitor 1 doesn't come up for 2-3 reboots.
Once monitor 1 comes up the other 3 usually follow, but many times monitor 3 changes resolution and acts like a larger monitor : when I drag the mouse across to get to the last monitor it scolls over like the screen is wider and longer than the 20" screen size.
I don't know how to fix this so I have to keep rebooting until the size is correct. The dispay properties say it is the same resolution as the others at 1280 by 1024.
Once that is fixed, the monitors are usually mixed, so in Display Props, settings, I have to move Mon4 between Mon1 and 2 to fix the order.

Then at times during the day one of the monitors will go black and in the display properties, I have to recheck the box " Extend Win desktop to this monitor" Then it usually comes back. But sometimes I have to reorder the monitors again.

A couple of weeks ago mon2 was flickering alot, so I changed it out thinking the monitor might be going bad. So I traded monitors with another dual mon pc and the flickering stopped. However that monitor works just fine on the other pc with no issues.

Then today Mon 2 blacked out and can't seem to bring it back. Disp Props shows it as being active, Device Mgr shows it is working properly, but no picture. The mon light is also green, it usally turns orange when taken off line.

Sorry for the long note - I wanted to describe all the problems.
Anyone out there with experience in 4 monitor cards ??
Thanks

hmm same problems ?? Interesting!
I have fixed 2 of my 3 problems. I returned and got a replacment card. Monitor 1 comes up immediately now and all of the monitors stay up all the time with no glitches. So that must have been a card problem.

The one problem I still have is on startup - monitor 3 is still an oversize monitor for the screen display. It takes over a dozen restarts to get all 4 monitors up correctly. In device mgr, it shows 8 monitors : 4 default monitors and 4 plug and play monitors. The correct ones are the plug and play monitors. I have disabled the 4 default monitors. But on startup the bad monitor shows as a default monitor, and 3 plug and play monitors. After a dozen startups or so, I get 4 plug and plays and I am ok.
So far the solution is just to leave the pc running all the time.
But I'd still like to figure this out. Is this a SW problem ?? or some kind of conflict ?? or maybe compatability issue. I doubt a card problem anymore.

I'm confused, the power requirements quoted on nvidia's site are of 35 watts maximum. Could someone explain why there would then be a requirement for a 350 watt power supply in the system?

Was hoping to use it to build a system with a low power need and passive cooling.

Thank you
