    Dell 4400 Dimension
    Operating System loads, but no video output. I disconnected the hard drives and was able to boot from a live linux cd, open a terminal, start other programs blind, including shuting it down from the terminal. I swaped video cards, checked the power supply, and other connectors with a multitester, and everyting came back great! The computer beeps 3 times during startup, and shows a blank screen on the monitor, like no one's home.

    Can anyone help?????

    Three beeps means no video card is detected.


    If you successfully used your video card in another PC and the same card fails to produce output on the faulty PC, then perhaps the PCI/AGP/PCI-E slot or the circuitry on the motherboard is bad, if I understand your situation correctly, which I'm not sure I do.
