Video card help? cannot get a signal?

Agree with the other two answerers ,you can't just simply hook up a new graphic card without disabling the intergrated graphic card or uninstalling the old graphic card drivers, take out the card restart the pc if a display ,go to the bios and disable the the onboard graphic card,shutdown and unplug the pc , install the new card ,plug back in , restart the pc, should have a display internal graphic vga driver kick in, if found new hardware show up cancel it , and install the cd software drivers

Use the PCI card. you may get get a no sign if the determination you place isn't known via the video demonstrate. This commonly happens with TVs. additionally some video demonstrate contraptions, like mine, will demonstrate the message for some 2nd as quickly as I first stat up the pc.

It will still be using your on-board graphics on your motherboard you will need to disable it first before you graphics card will take over

you might not have a powerful psu or your bios is set to intergrated video output and you need to change it to pci
