This should be a fool-proof procedure, selecting automatically between AGP or on board video.
If the other components, especially memory, are installed properly and you're not getting any beep codes, it sounds like a faulty board.

    Monitor says no video signal, not even from the onboard card. Do I need to get the DVI Graphics-SI card? I didn't get one with this refurbished board. I have tried PCI and PCI Express cards.

    1) Monitor plugged into the VGA connector on the motherboard, (Rear Panel), you should get a display.
    This is with the proper settings in BIOS.

    Reset BIOS back to the factory default settings, and clear CMOS Error Codes.

    Unplug the computer from power. (Monitor plugged into VGA connector on motherboard. No graphics card installed)
    Press the Power On button in, and hold it in for a count of 5 seconds. (Count 1001, 1002, 1003, etc.)
    Let go of the Power On button.
    Do this procedure 2 more times.

    Plug the computer back into power, wait 1 minute, turn the computer on.

    If you get OnBoard graphics now is the time to install the drivers for the graphics card.
    Then close all windows, turn the computer off, unplug from power.
    OBSERVE Anti-Static Precautions and physically install the graphics card.

    Still no?
    Time to enter BIOS Setup, and see what graphics settings you have.
    (When the post screen comes up press the F2 key)

    On the main page use the Right Arrow key to highlight - Advanced - at the top of the screen.
    Press the Enter key.

    Use the Down Arrow key to highlight - Chipset Configuration
    Press the Enter key.

    Initiate Graphics Driver should have - PCIE - to the right of it.
    This stands for PCI Express. This is the factory default setting.

    Internal Graphics Mode Select should have - Auto - to the right of it.
    With it set to Auto;
    The OnBoard graphics will be automatically disabled when a graphics card is installed.
    The OnBoard graphics will be enabled when a graphics card is Not installed.

    This is the download page from AsRock Support, for the User Manual for the AsRock ConRoe 945G DVI motherboard,

    On this page click on Click Here to the right of User Manual, after you have chosen what country that is nearest yours.
    Allow time for the PDF file to download. (Sometimes up to 30 seconds, and additional time may be needed to fully download the file)

    I would also like to know what Power Supply you're using, and if you are sure beyond a doubt that it is a Good unit.

    Can you elaborate the functions of this product....

    The following applies to motherboards such as an AsRock K7S41GX.
    It does NOT apply to motherboards supporting the Intel Core i3, i5, i7, and i9 processors.

    1) Motherboard diagram,

    A) CPU = Central Processing Unit. Another term is Microprocessor, or Processor for short.
    The 'Brain' of the computer.

    B) Front Side Bus. Also abbreviated as FSB.
    The FSB is the 'Information Highway' between the Processor, and the Northbridge chip.

    [Chip and Chipset are slang terms for I.C.
    Integrated Circuit, ]

    C) The motherboard chipset is the Northbridge chip, and the Southbridge chip.

    The Northbridge chip handles the faster capabilities of the computer.
    It is named NORTHbridge, because on the orientation of the motherboard, it is to the North of the motherboard.

    The Southbridge chip handles the slower capabilities of the computer.

    D) The Northbridge handles the Processor, Ram Memory, and HIGH-speed graphics.
    AGP and PCI Express are high speed graphic technologies.

    A graphics card used in a PCI expansion slot, and Integrated Graphics are NOT high speed graphics.

    E) The Southbridge handles Integrated Graphics, (OnBoard graphics. Same/same), and the PCI bus.
    A graphics card inserted into a PCI expansion slot is one example of Southbridge support.

    Any add-in card inserted into a PCI expansion slot, is in the PCI bus.
    Therefore handled by the Southbridge chip.

    The Southbridge chip also handles IDE (PATA), and SATA harddrives.
    Handles USB ports, Ethernet port/s, audio, and the CMOS memory.

    F) The Internal Bus is the 'Information Highway' between the Northbridge chip, and the Southbridge chip.

    G) The LPC Bus is the 'Information Highway' between the Southbridge chip, and the Super I/O chipset.
    The LPC Bus is also the 'Information Highway' between the Southbridge chip, and the BIOS chipset.

    H) The Super I/O chipset handles,
    Serial port
    Parallel port
    Floppy Disk Drive


    The AsRock K7S41GX has;

    A) Socket A processor socket. Also known as Socket 462

    Can use AMD processors that fit in a Socket A processor socket, and have either a 200MegaHertz, 266MHz, or 333MHz FSB.

    Here is the CPU Support List,

    Supports DDR Sdram ram memory at either 266MHz, or 333MHz.
    PC2100 and PC2700, respectively.

    Maximum TOTAL Amount of Ram Memory is 2GB
    Maximum Amount for EACH ram memory slot is 1GB.
    There are two ram memory slots.

    Has an AGP (Accelerated Graphics Port) graphics expansion slot, that supports AGP 4X , or AGP 8X graphics cards. (1.5 Volt)

    Has two PCI expansion slots

    Supports IDE (PATA) harddrive/s. (2 maximum)
    Supports IDE optical drives. (CD or DVD, or burners for both)

    The motherboard chipset is a SiS 741GX - Northbridge, and the SiS 963L - Southbridge

    upon checking your motherboard, it has an AGP port for video. so you have to get an AGP video card compatible. New video cards are PCIX capable which will not fit AGP ports..

    So you can get any AGP Video card and that should work.

    ASrock P4i45GV Motherboard

    Hi sandesh8, did you know you can increase the memory size of the onboard AGP card above the 64MB? Page 26 in you're manual. If you install another AGP card into the opened AGP slot, please go to this site & only use the recomended AGP cards in the Asrock list. Click on this link:
    This is one of very few video cards found on the list with 256MB of video memory.

    Good Luck!

    Any idea what the wattage of your power supply is?

    USB45 Socket connections

    You can download the manual here:

    which lists the pinouts for the onboard USB ports. I'd post the port info itself, but it is a graphic embedded in a PDF, so can not copy and paste it here.
