Issue in brief: System won't post if I have both monitors connected to my one video card. Unplug 2nd monitor, bam, system starts.

I just upgraded to Gigabyte SLI mobo, AM-2 5200, MSI 8600 (single) video card. Have FSB 450 watt psu, connected SLI power from supply to mobo. Ran XP disk and did the OS upgrade, installed all drivers, downloaded drivers for video card from nVidia. Bios is late version July 07.

Dual monitors worked with last (6600) card just fine. Main monitor is DVI, 2nd monitor is plasma connected at PCI using DVI to D-Sub adapter that came with the the MSI card since card has twin DVI ports.

I don't think this is a driver issue or OS issue since system won't even go to post. Turn on power, fans start, nothing else happens. Pull plug for 2nd monitor, restart, system starts fine.

Am going to clear CMOS. I don't have any other ideas.

[Edit] Cleared CMOS, checked for updated GPU bios (none available). System is now restarting with both monitors connected, but am not confident this will continue because it has started a few times, but mostly will not start.
