When I turn on my computer, it seems to be booting but yet all that happens is the monitor light just flashes green, and the monitor remains black. I checked the memory, power supply, video card, and monitor and they all work, should i assume that the motherboard or processor is dead? I bought another board, processor and memory, and would you believe the same thing happens too. What could be the problem?

Re: System wouldn't Boot
If your CPU or memory were an issue your Asus board would sound off with BIOS beeps. Asus uses the Award BIOS & you can see what these beeps mean at the link below. Regaurding your PC not able to boot is an issue with your PCIE/PEG video card-in relationship with BIOS setting & the SLI switch card mode that came with your board. When running 1PEG video card you must set this in the BIOS to Auto & you need your SLI switch card connected in its slot. By default, the EZ Selector card is set for a single graphic card. When you install dual PCIE graphic cards on A8N-SLI series motherboards, please make sure EZ Selector card set to the Dual Video Card side and properly inserted.

Will come in handy.
Reading the FAQ's at Asus site will help you better understand your A8N-SLI Deluxe. You'll need to fill in the, "Please Select the Product" first: http://support.asus.com/faq/faq.aspx?SLanguage=en-us

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: http://www.pchell.com/support/safemode.shtml
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.
If the cpu were damaged, you would still get something at boot.
Smell your power supply? Do you smell arcing or burning. If so, it may be your power supply. You can get a power supply tester for about $20. The power supply has several different voltages that it supplies. So, the system might seem to be on but not really.
Depending on the size of your system, you can get a power supply for between $20 and $125.
I am willing to bet that it is the power supply. A cheap power supply can easily burn out.
I know, this is a very frustrating situation... Unfortunately, the only reasonable way to find out what's wrong is to swap components with a reference system, until you found the defective part. I hope you have another P3 system available to swap parts.
I would do it this way:
First check that the power button is connected correctly.
Swap the memory from the faulty system to the reference system.
If ok, put it back into the faulty system and connect the power
supply from the reference system (or some other known good one) to the
If this doensn't help, swap the CPU from the faulty system to the reference system.
If the CPU is ok, the motherboard seems to be defective.
Now when you say blue power light, what are the rest of the lights doing, does the hard drive light flash, does the fans turn on, does the hard drive make it's spinning noise, if so you may just have a bad LCD inverter which is very common and about a 40$ part. you can test this by trying to hook the laptop up to an external monitor and see what happens.
i am also using same motherboard dg31pr intel but it does not reboot .......
because this is the problem with you monitor , just you change the monitor and try again .
this is only the solution to solve this as the tecnition said me.
Try another (Known good monitor). Or try you're monitor on another system.
Remove all memory except 1 DIMM. Double check all data cables (internally) & power cables. Remove the added video card. Try booting the system. Watch for the case LEDs to flash/blink, listen for hard drive spin up /cd-rom spin up. Lastly pull the battery & check with a volt meter. Bios battery should test no less than 3 volts. Post the correct MD rev.
I am having the same issue. Clearing/reset the bios will get the board to boot up, but when turned off and started again the board will not boot. you will have to clear the bios again. The board seems to be rebooting itself continuously before it evens get to the POST.
Sounds as if your power pack might have a problem.blown fuse ect.I whould remove the cmos battery and or change jumper pin setting to start fresh in the bios settings.after removng the cmos battery,Make sure to put it back in before you re boot your computer. Good Luck garydalel
