Re: No Video

Check your power supply. It needs to be at least 300 watts, 350 is better.

I bought Foxconn 755A01-6EKRS Motherboard for my HP pc replacement. i install my AGP VsionTek x1300 graphic card and turn it on and nothing show up on screen...then i put the graphic card back to my old HP...

Your new Foxconn motherboard Primary Graphics Adapter settings in set to onboard vga that is why there is no display in your monitor. Do not install yet your agp video card. Use first the onboard vga of the motherboard.
Power up your computer and go to the BIOS settings. Locate in bios about the Primary Graphics Adapter settings and then select AGP. Save changes and the exit. Turn off your computer and now install the agp video card.

Biostar u8668 grand does not power up when agp

Good Day sir, try to check the CMOS/BIOS setup, and go look for Initial Display First, there are several options, Onboard / AGP / PCI. OR, after you remove your AGP, clear the CMOS/BIOS setup. find the jumper wire near the battery this sets your motherboard to factory setup and uses the onboard VGA. test the pc without the AGP.

Disable video graphics onPTGd1-LA

Every motherboard manufacturer has different ways of implementing the setting up of the display priority of the slots. If you add a PCI-E or AGP VGA card on a based board, there's no problem for the board to see your add-on card as the first display. If you add a PCI-E VGA card or a AGP/Super AGP VGA motherboard board, you will need to set up the display priority. Every board manufacturer has its own system of setting the priority up. Some of them will implement it in the BIOS, in the item "Integrated Peripheral"," Initial Display First", you can choose "PCI-E or AGP slot". However some other manufacturers implement the settings by using jumpers, if this is the case in your situation you will need to refer to your manual or contact the manufacturer for further help. The best solution is to seek help from the manufacturer of your board. Hope this might very helpful to you and good luck!

Motherboard installation

Hello mecompe,

If you installed an AGP graphics card before your fist boot of the system, you will not receive display. By default the onboard graphics is set to boot display. (If this is the case, remove the AGP graphics card & boot the system). The Asus P4SGX-MX can only use a 4x AGP 1.5volt (only) card.

There is an order of sequences to perform before installing/ adding an AGP graphics card on to the board when the board also uses an integrated graphics card.
First, shut down the system & unplug the power supply from the PC. Connect your monitor to the VGA port at the rear of the board. Remove the AGP card. Re-connect the power supply & boot the system. You should have display? Re-boot the system. As the system starts up press the delete key on the keyboard every 2 seconds. The bios main menu will load. (Open your manual). Go to
section 2.4.3, page 2-20 under Advanced, PCI configuration. Set Primary VGA bios to
[AGP VGA Card]. Save the bios & exit. The system will auto restart. Press & hold the power on/ off button on the PC case until the system shuts off. Unplug the power cord from the PC. Insert the AGP card into the AGP slot. Connect your monitor to the AGP card.
Check all internal data & power cables, (Incase something came loose). Re-connect the power cord & boot the system. You should have display! Install your video software.
If your using the integrated VGA PCI graphics card, go over the bios settings page 2-18 & 2-20.

Need the Asus manual? Click this link;

To view the manual you'll also need Adobe PDF reader, click this next link for Adobe.

(The green led (light), means standby. The board is receiving 5volts DC.

If you still do not have display just let me know.
Good luck mecompe!

Vga display problem

There is one pin/wire on the VGA connector that translates to the color red on your screen. If you aren't seeing any red, I would suspect that there is damage to the integrated VGA connector on the motherboard, or a component failure in the circuit.

These are great desktop boards.

The Video bus on these boards are shared between the integrated (onboard) video card and port and the AGP slot. This means that you can only use one or the other. When you install an AGP card in the slot it overrides the integrated video including your problem.

If you are good with electronics I'd take a look at the board under the scope and look for damage.

I would rist check with intel on the warranty. You may be surprised. I've had several of these replaced via RMA through intel. They are a bit older but still by desktop board of choice.

Hi sulip, your board uses an Integrated nForce 2 with TV-out video card. The nForce shares your system memory to function.
If you have not made any changes to your system memory, I suggest you follow these steps.
1. Please upplug the power cord from the PC
2. Remove your system memory (if more than one DIMM is being used), remove one at a time.
3. Using some house hold alcohol & a cotton swab lightly damp, clean the memory's copper contacts.
4. Blow out the DIMM slot with canned air. (If you have some).
5. Firmly & evenly re-install the DIMM. Do the same to the other DIMM.
6. Plug your power cord back in & start the PC. (do you have display)? If yes than we are all done.
If no, than recheck the cable connection from the PC to the monitor. (good connections). If possible test your monitor by hooking it up to another PC or notebook.
Your board can also use an AGP 8x 1.5volt (only) video card.
You can buy an AGP card or borrow one from a friend & add it to your system. If you get display with the AGP card than your integrated video card is defective.
In case you need to buy an AGP 8x 1.5v card you can find one at this link below.
This card uses the 1.5 volt spec.
It also has a Lifetime Warranty.

Good Luck!
If I can be of more service, just ask.

New graphics card not recognised

Peter, you need to enter your bios & make a change.
How to enter bios? Start the PC & begin pressing the Delete key every two seconds untill the display screen opens to the bios menue. Peter here at the main menue of your bios look to
Pg. 29 in your motherboard manual. If you do not have your manual download it from the link provided:
In order to move about in the Bios look at the bottom of the screen. There you will see how to move about using your keyboard.
Take your time in the bios. It can be confusing, even for me!
On pg. 30 change the Video (EGA / VGA) to AGP if available.
If AGP is not listed do not change.
Go to Pg. 35&36
Advanced Chipset Features
AGP & P2P Bridg Control Change to AGP if listed.
VGA Share Memory Size Change to 0 if possible.
The onboard/intergrated AGP uses part your system memory to function.
AGP & P2P Bridge Control
Play it safe & change to the size of memory to 256Mb.
Which matches your FX5200 memory
AGP Fast Write to Enable
AGP Driving Control set to Auto
AGP Master WS Write to Enable & same for Read.
Save & exit bios. The system will re-start.
If after your system starts back up & enters into windows & you notice you do not have video switch the cable connected to the other VGA out-put on the FX5200. Your display should show up.
Install your software for your new card.
If you have troubles Pete just post back here & I'll address them.
& please vote...

Intel P$ 1.8 mhz on a D845HV/D845WN board

Before removing your current card swap video outputs on the PC. If currently connected to the VGA output switch to the HDMI connector AT the video card. Use the HDMI to VGA adapter that came with the video card. Check & see if the display loads Pc starts. Taking the information directly from your motherboard manual pg. 25, your AGP video can only run at, AGP supporting 1.5 V 4X AGP cards. The 9600pro runs at 8x & it is not backwards compatible. (able to run at either 8x or 4x). You could run the Sappire ATI Radeon 256MB 9550 DDR AGP 4x/8x 1.5volt card.
Here is one site:
When you do get the video card be sure to set your bios AGP to the correct size as listed in your manual pg. 109 subsection 4.4.7
I hope this helped.

Video signal

If it worked fine before the AGP card was removed then the problem is probably related to your BIOS settings. The BIOS setting that controls the integrated video may be set to OFF.
  1. Insert an AGP video card
  2. connect the monitor to the card
  3. boot to BIOS
  4. check settings
  5. turn ON integrated video
  6. save and exit BIOS
  7. shutdown
  8. Remove AGP card
  9. connect monitor to motherboard video port.
  10. Reboot.

What happened?

How to disable onboard VGA

I believe if you install an AGP card the onboard VGA is supposed to be automatically disabled. Did you buy an AGP card?
