Re: Boot Problem

It sounds like you are stuck in the bios. There is several way to reset it


1 - If you have your motherboard manual look for instructions on how to reset your bios. The is a jumper (set of pins) on the board that will reset it.


2 -  Unplug your unit from the AC, open the case. Look for a lithium battery and remove it. In the battery socket short the led?s for about 30 seconds. replace the battery close the case.


Note - Be careful when removing the battery.

Re: Boot Problem

This motherboard has the Nvidia graphics (GPU) which is BGA (ball grid array) soldered to the PCB (printed circuit board). Instead of using pins on the chip that are soldered through the PCB it is instead sat on top of tiny solder balls that fuse it to hundreds of 'contact pads' on the motherboard when it is heated during manufacture.
Due to the impressive performance of the little Nvidia GPU, it generates quite some heat and the lead-free (WEEE compliant) solder cracks and the whole board fails.
It seems that manufacturers do not want to go back to the reliable 'pin method' as it costs more money and fitting a bigger heat sink, especially in laptops would make them bigger and less saleable!
It seems that although a bigger heat sink is fitted on these motherboards it is made from a crappy light-weight aluminium metal with an inadequate thermal pad and a limp sprung tensioner to secure it.
Inserting a PCIe / AGP card after the Nvidia failure will NOT bypass the issue most of the time.
Your best bet is to heat the chip with a blow lamp (unless you have a re-flow station) but as gingerly as gingerly can be, i.e. don't toast it to the board until it is on fire. And don't press it down either!

If it didn't work then you haven't lost anything, being that you

My pc dont show any thing axcept blank display with i tried to change graphics

Maybe one of your memory chips is bad.

If it seems to boot up all the way except the display is blank try the steps below:

Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor display the desktop then the original monitor is bad, but the video card inside the computer is ok. If the Borrowed monitor does not display then the video card inside the computer is bad.

If it does not seem to boot up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

When I turn on the computer and window boot up .My montor will flash green, red, and blue colors.

This will happen for one of two reasons:

1] No input to your monitor (i.e. there is power to the monitor but it is not getting a VGA feed from the PC)

2] The monitor does not support the Display resolution that is set on your operating System.

If you have set the resolution to high - you will have to boot into SAFE mode if you are using windows and set the resolution lower. To boot into safe mode - follow these steps:

Once in safe mode. Right click on your desktop. Click on Properties, Then click on the Settings TAB and slide the resolution toolbar down to for example 800 x 600 Click OK and reboot.

Hope this helps.

Good luck

Check that the + and - for the power button connecting to the MB is correct. If everything is new, it is possible the board is DOA (happens).

Motherboard problem.

Test the motherboard with nothing attached to it except the monitor, mouse, keyboard and the power button. If you can't still get into the bios then try again with another memory and processor. If it's the same then it's dead, junk it, it's unfixable.

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!
