My n1996 onboard display card doesnt displsy any more, can i use an another AGP CARD

Your board has S3 graphics and if you would like to try and find drivers for that this is MSI's link;
I don't know what version of windows you are running and/or what the exact problem is with your graphics however, to answer your question, Your card will accept AGP 8X, 4X cards and, as long as you have an operational slot open, yes you can use AGP cards. If you have upgraded to Windows 7, you can find cards that have Windows 7 support.

Self having the following configuration on Home desktop PC. INTEL 1.7GHz, P4, D845GBV motheboard with AGP ATI Radeon 9000 graphics card, RAM is 2 x DIMM DDR2 266 Hz, 1 x 1GB + 1 x 512MB total 1.5GB RAM....

Power down and disconnect AC power from your PC. Remove the AGP card and DIMM again and use some "canned air" or dusting spray to get any dust off the contacts on your motherboard and your memory and AGP card. Wiping the AGP card contacts with some isopropyl alcohol (also known as IPA or "rubbing alcohol") and a clean, lint-free cloth can also help. When everything is dry, put your card and memory back in and try powering up again.

No display on monitor & if ram open and restart on then no sound on buzzer.

*Please Read full post before trying Also download the Online manual for this motherboard it takes only a minute and probably will answer a lot of questions you might have regarding *********** Board.*

Um... i am assuming your able to still see the display on the monitor if you plug your monitor into the on board video card. I am also assuming that the problem your talking about accursed when you plug in a video card into *********** board and then plug your monitor into that video card. I am also assuming your graphics card that you want to plug into *********** board is a AGP slot card.

If both of these conditions apply to you then try this.

Start your computer with your on board graphics card and unplug any other graphics card form *********** board.
Next go into your bios, and follow these instructions:

Go to "Advanced", "Chipset", And then "AGP configuration".

Next change your "Select AGP 3.0 Data Ratio" to "4X".

Next change your "Graphics Adapter Priority" to "AGP/Int-VGA"
*make sure its set to" AGP/Int-VGA" or your display will not work and you will need to reset your bios via the mother boards jumper cables.*

After that hit esc and go to "Exit" select "Exit

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!

Video controller problem PLEASE HELP !!!

Hi bullterrier0,
The Asus P4S8X-MX uses an onboard video controller, (SiS Real 256E graphics card).
There is an order of sequences that must be followed when adding another video card on to the motherboard. If these are not followed your new card will not function correctly. Shut down the system. Unplug the power cord from the PC. Open your case.
Please remove any graphics cards you may have added into the system, (For now). Once removed leave your case open & plug the power cord back into the PC. Press the start button. Start pressing the Delete key every two seconds as the PC starts up.
The bios main menu will load. Instruction on how to move about within the bios is listed at the bottom of the menu. You will need the P4S8X-MX manual. (If you no longer have the manual you can download it from Asus by clicking on this link:
Click the plus sign next to; Manual. Find the English manual.
Create a folder on you're desktop & name it Manual. Download the manual. Save the manual into the folder. The manual will need Adobe pdf reader to be viewed. If you do not have Adobe you can download it for free from this link:
Once into the bios go to the title Advanced, page 2-17 in your manual or page 59 in Adobe pdf viewer. Open Chipset sub-menu.
Than find, Primary Graphics Adapter page 2-21 in manual, pg 63 in Adobe.
If the TV turner card is an AGP set this to [AGP] & set AGP Fast Write Control to [Enabled].
If you are using a PCI TV tuner card set this to [PCI]. Save the bios & exit. The PC will auto restart. Press & hold the power on button until the PC shuts off. Unplug the power cord from the PC. Re-insert you're AGP TV video card. Double check all internal connectors for good connecting before closing the case. Plug in the PC's power cord & start the system. Once windows has finished loading install the TV video cards driver software.
If you installed software drivers for the P4S8X-MX other than driver software provided by Asus please uninstall that software through Add/Remove programs. (If at all possible).

Since you want to use a TV video card you can not use the onboard graphics card at the same time. This is why windows was restarting. Windows did not know which card to load. Once the onboard card has been disabled by telling the bios to load the AGP, (Assuming you're TV card is an AGP card) windows should run fine. There is always the possibility I interpreted your trouble incorrectly. If this is the case, please let me know & I'll adjust my answer to fit the issue.

Good luck bullterrier0!

Brand new geforce 6100 pm -m2

This is for the EliteGroup P4VMM2 motherboard. Please remove any newly added video card. One done boot the PC. Windows should load & function (Including video display). Yes?
Restart the PC & press the delete key every 2 seconds untill the bios menu loads. Opem the manual to page 33. Change the Primary Graphics Adapter from PCI to AGP. Save & exit the bios. The system will begian to restart. Press & hold the power button untill the PC shuts down. Unplug the power cord from the PC. Install the AGP card & connect any additional power to the video card if required. Double check all data & power connections for good fit before closing case. Re-connect the power cord & start up the PC. You should have display. Allow windows to finish loading & install the AGP software. Than update windows.
Who ever heard a single long beep. This means the video card may not be seated fully & or correctly. Remove the AGP card, blow out the AGP slot with canned air. Take some alcohol dripped onto a cotton swap. Clean the AGP's copper contacts & clean/wipe the copper within the AGP slot as best as possible. Allow time for alcohol to dry. Re-insert the AGP card, firmely & evenly.
Any more troubles? Please list the issue here. Need manual for the EliteGroup P4VMM2? Click on this link:

Good Luck!

GeForce4 MX 420 Video Card

First question: Are you sure you have a PCI card?
there are several points here:
Make sure you have the monitor connected to the correct output on your computer. (In this case to the output of the graphics card, not to your onboard output)
If you have a PCI card set bios to PCI
Setting it to AGP means the computer is looking for a graphics card in you AGP-slot on you motherboard.

I cannot help thinking, that you actually have a AGP card in a AGP slot and that you computer is not working on onboard, but on AGP. But you can check which graphics device is used, in display properties (right-click Desktop, Properties, Settings)

Please post some feedback

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...
