OK, I downloaded the manual & had a look at the BIOS section. You probably have these set correctly, but it won't hurt to double check.

Under Advanced Chipset Features, set the 'Frame Buffer Size' to disabled. 'Bank Flip' & all Spread Spectrum options should also be disabled.

Under Integrated Peripherals, set 'Onboard GPU' to Auto.

Under PnP/PCI Configurations, set 'Init Display First' to PCIEx. Set 'Reset Configuration Data' to Enabled.

Save & Exit.

Users & techs are 2 completely different things ;-)

You need to disable the onboard in the BIOS & change the primary display setting to the PCIe slot. You moved the monitor cable from the onboard to the card, right? And I assume you have a 24-pin power supply with adequate amperage on the +12v rail? The 6-pin PCIe plug is connected to the rear of the card (if required)?

PCI-ex is main by cmos defaults, but i double checked it. this pc worked before, i only changed motherboard. 8600 gt is asus silent edition and it doesnt require extra power, it supplies only from MB. Yes, ive tried disabling onboard vga in device manager and then shutting down pc, moved cable to 8600 but when i turn on pc i dont get picture, so in the middle of work i turned back cable to integrated and it still works. Ive read multiple threads about similar issues but simply cant find solution..

Thank you very much for your time, after extensional testing ive figured out that 2 graphics card i owe are dead. finally after i put 3rd card, 8600 gts i got pic from the first time. It seems that cmos default settings was ok, it booted that card right away without even displayed integrated one in device manager. It took me 4 hours but at least i know what caused me all troubles. Thank you all again :)
