Re: Computer shutting down.
Hi tenbear8, I checked the bios date for the motherboard. I'm guessing this board came out in late 2005. Asus warrants their boards for three years. With this in mind it’s worth a call to Asus tech. Open you're case & find the white sticker on the LPT port. Write down the information there. Call Asus M-F 8:00AM to 5:00PM EDT. The number is 1-812-282-2787. You will not be on the phone very long before a tech picks up. (Free support). The tech will want the information you wrote down from the sticker. In the mean time update you're bios with the latest flash. Bios number 0809, it has a fix for CPU string correction in the bios. It may just do the trick. Click here for the link to P5VDC-MX download site. http://support.asus.com/download/download.aspx?modelname=P5VDC-MX&SLanguage=en-us Download the bios file & download the Bios Utilities. Either way it will not hurt to call Asus even if the bios flash fix's the system. The more information you can get from Asus the better. (They know their boards better than anyone). If you're board is bad Asus will know & if it’s still in warranty you're looking at receiving a replacement board. Nothing to loose & everything to gain.
Good luck tenbear8! Please let me know how things work out with Asus.

That means that the monitor is not getting a signal from the computer. There are several possible issues involved. 1) Make sure that the computer tower is on. 2) Check that the video cable is connected to the active port on the desktop. (Computers often have video connections on the motherboard and an added video card. The motherboard connection is disabled when the video card is active. Similarly if there are several ports (VGA, DVI, HDMI, Display port) only one may be active.) 3) Try a new video cable (if possible) and one of the other video ports (again if possible). 4) Try connecting a different monitor to the computer or connecting this monitor to another computer.
Open up the computer and check if the card requires a separate power connection to the power supply. Make sure it is plugged in. Do the fans in the computer spin up?
If a second monitor doesn't work or the monitor works on another computer, then the problem is with the video adapter on the computer, the power supply or the power switch. Please add a comment with more information about the type of desktop and the current video graphics adapter (on the motherboard or separate card). I will provide additional help if possible.
Cindy Wells (who has a computer in the company that needed a new monitor (power supply failed) a few months ago and lost the fan on the video card last week. Without the fan, the card overheated and shut down. Thus no signal to the monitor.)
what u may have done is wwhen u were installing the new board, gave a static shock to the system...that will cause only the fans to come on and nothing more...this is a bad problem bc u cannot fix it...if u figure out something else is wrong, and it gets fixed, let me know
The fan should run constantly. It needs to be replaced. Otherwise the power supply will shut down when it gets hot. It can usually be replaced, but if the supply is cheap, just go out and get a new one.
It was a faulty or worn out power supply fan. I just replaced it and the computer has been running for about an hour and a half and still no shut down. The system temperature is stable. It runs quieter now. New fan cost 13.88CAD.
If the computer shuts down with no warning then it could be your power supply is faulty, which explains it not turning on sometimes. Just check the back of the PC to make sure it is plugged in properly (TURN OFF ALL POWER TO THE PC BEFORE CHECKING). if this does not help, get it looked at by your local qualified computer technician if you don't know how to replace a power supply. Also, a connection to the motherboard to the Power button may have a fault somewhere, which also means take it in for a look if you don't know what to do. If it does give you warning with 'Windows is shutting down' it can be the following things. 1- Your power button on the PC is sticky and movement causes the computer to think you have pressed it and so it shuts down, which can also explain why it wont turn on all the time. Just use some household grease cutter and spray it on the outside of the button, turn off the power supply to th computer and press it in and out a few times to get it back to working order 2- A Virus is shutting your computer down on you, but this does not fully explain why it won't turn on but this could be an effect of the virus so use a virus checker to see if this is the case 3- Your computer system is getting too hot and usually a computer has setting which shuts it down before permanent damage happens. Check your PC fans to make sure they are running and feel around where your computer sits to see if its warm or hot and replace the fans or put your PC in a cooler environment
check the fan (top rear of the computer) , make sure it runs when you start the computer. if it is NOT running the power supply may be the cause.
also you may need to remove the case and inspect the fans inside. you shoulkd be able to remove a couple phillips head screws on the back of the computer and lift the cover off or at least the side making the guts of thhe computer visible.
once open , inspect all the fans and cables, especially the fan on the main board and the metal piece with fins undernieth it, this tends to collect dust causing the cpu below to overheat and shut down the syatem to protect itself. The number one cause of crashes is overheating.
look at these things to start and post your findings and we'll move on to another step.
That is an impressive wait. You must be an OR LP to have tolerated that battery manipulation; hopefully the surgeons aren't up nights over the 3 lost insulated forceps.... It sounds as though the system is dissatisfied with the CPU fan speed or another power/cooling interface component (CPU over 90 centigrade, chipset over 95 centigrade, the power supply fan running, etc.) and thus shutting down immediately to protect itself. Do all those things check out, particularly in the BIOS power/cooling section? How about fan and power connections on your videocard being right and jumpered accommodatingly?
That is, you could connect tach fans on any spare 3-4 pin headers and see if favor comes your way. The system will spin them slowly once it boots and you enable automatic CPU/fan control (and power savings) settings.
Maybe you have not put the correct fan on and it has shut down to protect itself. Processors overhead catastrophically in a matter of seconds. Also did you connect the fan to a power supply on the motherboard.
