Question about ASUS A7V8X Motherboard

1 Answer

No video Hi I have a HP with this motherboard with all disconnected except for main board I turn it on the fans both work, the keyboard lights up but I get no video. I placed a new video card in the video pci slot on the board and still nothing the monitor show no picture what so ever as if the board lost the Bios. with the memory pulled I have no beeping from the sound so it isn't the memory but it will run on and on as if there was nothing wrong. Check the battery on the board and that was good I figure it is either the board or the chip

If there is problem in bios then you can recover bios by changing the jumper to recovery mode ..
for this you can refer to your motherboard manual ...


due to this you might not getting the video ....
or there may be some problem in the cable of the monitor or pin ...
or the video card might not have placed correctly remove it & reinsert it & then try..

if you still persist the same problem then the IC might have gone which will be near the PCI slot ...
so you just have to contact the motherboard technician & get the IC replaced ...


any doubts you can reply me

thank you

Motherboard Power Problem


Hello Alienware,

Could be a few things.... such as the micro-fuses that have gone on the MB....

But what I dont understand is this:...."Then I disconnect the 4-pin cable that goes from the Power Supply to the motherboard near the CPU and the pc turns on fine"

How????
You have just disconnected the cable from the PSU to the motherboard....it CANT turn on! LOL.

Do you mean that the lights turn on?
Or you hear the HD spin up (if you left it connected to the MB that is)?

Please advise so I can help you more.

Hi, you better use usb mouse, the one with light at the bottom to see if it is on after you power on you pc. If you did not see the light on, that means the video chip on the motherboard or processor is bad. You have to try 1 memory at the time, then try the processor, if it is still not working, the motherboard is bad.

Yes it could be a video/motherboard problem.
1st Install a different RAM module because the RAM may be faullty and the on-board video card uses part of the RAM (shared memory).
If this works then the RAM is either faulty or incompatible.
2nd. Try installing a video card in the AGP expansion slot.

Cant get computer to


Disconnect everything from the motherboard except the power supply, CPU and power switch.

Turn on the computer. You should hear 3 beeps because you removed the memory.

If you don't hear any beeps, check the power supply. Check all the connections. Did you connect the 4 pin power? Did you skimp on it? A common mistake is to get a cheap, high-power supply. Just because the box says it's 1000 WATTs doesn't mean that will carry a steady load.

Still nothing...

It's either a bad motherboard or processor. If you have another processor that is supported on that board and you know it works, try it. If it boots return your CPU for a good one.

Unfortunatly, if it doesn't boot with a known-good processor that just proves the board is bad; it doesn't prove your CPU is good. You may have more issues.

No disply of my motherboard plzz help mee.


Good day sir/maam, hi, if your motherboard wont turn on, you need to make sure that these 5 things are in good order. (By the way, disconnect everything except these listed 5.)
  1. (PC is on) Your power supply, make sure that the exhaust fan is spinning as you turn it on.
  2. (PC is off) Your memory module, (ddr1 or ddr2) clean the contacts using an eraser(pencil) the gold plate contacts and a clean brush your motherboard memory slot.
  3. connect the casing's pc speaker on the motherboard.
  4. connect a video card, make sure its good. If you are using the motherboard's VGA, dont connect a video card. Temporarily reset the CMOS, use or locate cmos battery jumper setting. usually its 1&2 set the jumper to 2&3, then back to 1&2. connect a good monitor.
  5. Connect a keyboard.
Now power on your PC, check your Keyboard, you should see two sets of lights: first set (NUM LOCK + CAPS LOCK + SCROLL LOCK) then a few seconds the second set (NUM LOCK only). at this point you should hear a beep from the PC speaker.

If not, you may hear 1 long and 3 short beeps. bad video card. OR continous beeps, bad motherboard.

If you did not hear anything, do it all over again several times.

Still not working? replace your motherboard, its bad.

hope this helps.

PC is dead after clear the BIOS


Put the memory back in the computer first. (only one stick if you have more than one)

You are going to have to start with basic troubleshooting first.

TAKE notes as to where cables were etc. (digital camera would be useful here)

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the on-board)
Disconnect all drives

Power u the computer and make sure you can at least get into the BIOS.

If you hear any beeps these can indicate where the fault is.

Power up the PC and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.
Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

If its not the PSU and your fans are working it may suggest a problem with either the motherboard or CPU

Hi there, I installed a motherboard p4vmm2 and can't get the monitor to get a signal or to get the keyboard to power-on. Any help in this matter would be greatly appreciated. Thanks in advance for all your...


if you cannot get the keyboard to power on, and i assume there are only USB ports on this, means that you cannot work with the BIO settings.

no luck there, return it.

if you can't return it, jumper setting on the motherboard allows you to reset the bios to factory default, if then the USB keyboard still doesnt work, probably a dead board.

No display on GA 81G1000 mk motherboard


Some history would be appreciated.
Has this computer ever worked?
Have you recently added new hardware or software?
Has anything happened recently that may have caused this (lightning storm, etc.)?

If the computer was working fine and for no apparent reason now won't POST, first remove everything from the outside (keyboard, mouse, etc.) except monitor. If that works, one of the items you removed is causing a problem.

If not, unplug power, open case, remove all expansion cards except for video, then try again. If you have never worked inside a computer, some help from a knowledgeable friend would be advised. Be sure to touch the metal case before touching any circuit board inside the computer.
Also disconnect the cabling from all of the drives and then retry boot.

Let me know if this helps. If not, we can do more providing you are comfortable working inside the computer at my direction.
