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.

(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!

Hi mecompe,
Is this Asus a new used board? When you attemp power on, does the CPU fan spin? Can you hear the hard disk drive spin up & cd-rom drive spin up? If you watch the front of the case do you see any led's flash, like your floppy disk drive, hard drive led (AMber in color), cd-rom drive led & green power led on at the front of the case?
The green led on the board means standby, the board has 5volt power, thats all.
Are you using the onboard SiS Real256 graphics card or installed an AGP graphics card, & if so what is the model type (ATI Radeon ECT)? Is the AGP card 1.5v compatible?
What is the total wattage output? Example:(300w, 350w, 400w ECT)?
Understand all of the questions are relevent to your issue. Answer with as much detail as possible.
