8600 GT Dual Monitor Problem
I hope someone can help with this problem.

I built a computer for a relative who lives cross country.

The specs are as follows;

PNY GeForce 8600GT PCI-E x 16
Biostar TF560 AM2+
4 Gigs DDR2 Ram
2 - Maxtor Sata 320 gig H/D's in Raid 1/0 configuration
AMD 5200 AM2 CPU
Vista 64bit Ultimate
Thermaltake 550 watt power supply.

Here's the scenario and problem;

When I built the system I used my 19" LCD VGA monitor to install the OS and update all the drivers. I used the VGA to DVI adapter for the connection to the video card.
I used the port just below the HDM-I (?) connector (Top of card).

Shipped it out to him. He has 2- 22" Samsung monitors with DVI connections.
If he connects only 1 monitor to the video card and uses the connection I used, his system won't start. It acts like the power supply is shorted.
If he tries the other port, the computer boots up and runs fine.
If he connects both monitors, the computer acts like it's shorted out again.

Tried both monitors in different ports and can only get one monitor to work.

I used the Nvidia driver that was released in July.
Also on a side note, when I was setting up the computer I installed Ntune. But I had to uninstall it because every time I tried running it I kept getting a SeaCache (?) Device unknown error.

Thank you,
C. Katz

Fixed!!!
:D

Even though I'm using one Nvidia card and 2 monitors of the same model it seems Aero was the issue.
Turned off Aero, shut down, connected second monitor and it booted right up and got the dual monitors configured.

This Microsoft article got me thinking so I tried it;

[url="http://www.microsoft.com/whdc/device/display/multimonVista.mspx"]Vista Multiple Monitor Support[/url]

So even though they say Aero will work as long as only one graphic driver is used, this problem may apply to to any setup.
