If you go into device manager and under display adaptors do you see the 4350 there? You may have to enable the card if it is there and says it is disabled.

This sounds like a problem you would normally see with older motherboards but it still happens, go into your bios settings and disable your onboard video, connect your video card and see what happens.

By "onboard" he means the graphics chip that is literally on the motherboard, not the graphics card.

Hook you monitor cable to the "Built-In" graphics card, then go to your BIOS and disable it. Or make the PC boot from the Add-in gfx card.

Then turn off PC, hook your monitor cable to the discrete gfx card (HD 4350) and you should see singal from screen when you turn on your PC.

ok heres what you do, hook it up form the onboard WITH the video card plugged in, go into bios, disable the onboard and then save settings and reset, then unplug the vga from onboard to the card

do all of this while the 4350 is in there
