I currently have 3 monitors hooked up to my system. Onboard video (NVidia 6150) displays all colors properly on monitor 1, but the 2 monitors that I currently have hooked up to the 450G (both hooked up to the top video output to a 2 way DVI splitter and then through dvi to vga adapters) are showing up in some funky colors. My desktop expanded to monitors 2 and 3 just fine, but monitor 2 is red tinted and mionitor 3 is green tinted. I have th emost current driver form the Matros site. Any tips?

Hello ghinea18, sorry you can't do that because this will cause hardware conflict, that's why motherboard bios automatically disable integrated graphics if you install video card using pci express x16 slot - Nvidia GeForce 7300SE. do you know if your video card has dual vga or dual dvi connection?
You can try dual display, im not sure if this card supports dual monitors because nvidia online specs does not show full specs on 7300se series. \
Have you checked the bios to see if onboard graphics have been disabled.
You may also have your resolution/refresh rate set to high for the new monitor.
Boot into safe mode (F8 on boot)
This will boot with minimal drivers, your monitor should now come on, if it does then go to you display settings and lower the resolution and refresh rates.
If it does not come on in safe mode, try hook up the old monitor, or another monitor to reduce the resolution
It appears something has happened with the video card or connector especially if it displays fine with the onboard video and original memory. Disconnect power and reinsert the video card into it's slot.
simply install another video card or get a card that has two outputs no pc will work with more than two video cards but the best setup is 1 on main board and one in the agp slot . or 1pci and 1 agp then enable them in your display settings :)
Check bios settings. ie. disable onboard video, enable PNP OS installed, enable "assign IRQ to vga", disable shadowing and caching, enable passive release, enable delayed transaction, vga boot sequence: AGP, set graphics aperture size to 128MB, disable turbo modes.
Verify power supply is at least 350 watts.
Reboot into safe mode (press F8 right after the BIOS POST screen and before the windows loading screen) and use the program, Driver Cleaner Pro to remove Nvidia video driver remnants. Don't select all of the options, just the Nvidia driver and the plain ATI selection.
Verify the monitor cable is securely connected to both the monitor and the computer.
Verify that you have connected the cable to the vga port on the card and not the onboard vga port. (I'm not implying that you are dumb or anything like that, but sometimes even the best of us, overlooks the simple things... especially me! LOL)
Verify the monitor cable is good.
(Last but not least), try using another monitor to test. (Could be an incompatibility with the monitor.)
