Question about ASUS A7V8X-X (90-M7A690-W0EAY) Motherboard

Installed new mother board, bad things happened.

Hello, I just installed a replacement motherboard and now I am having technical problems out the @*%. First, I made sure I was grounded, and then I screwed the motherboard into the case. I then hooked up all of the drives, cards and wires. So I thought that I was all set. So I plug in the power cable, monitor, keyboard and mouse. I turn on the computor and get to the bios setting page, and then it turns off. Everytime after this, the same thing happens. I take out the cmos battery, and then nothing happens, After that I move the jumper to it around, after going to a couple of forums, and it gets the fans spinning. But that was it besides the disk drives. I made sure that I was grounded while having an open case. Is there anything that I can troubleshoot to maybe get everything working again.

Hi Willy,
Sounds like you have a faulty memory stick.
You did not say if you used your old stick or replaced it with a new stick!
If you are using your old stick or sticks, MAKE SURE they are compatible with your new mainboard.
At one time, you could use a slower speed memory stick and the board would operate but with the memory bus at the slower speed of the memory stick, HOWEVER, this is not true nowadays!
You cannot mix old and new sticks, nor can you use the incorrect stick. Even if the stick fits into the same slot it may still not be compatible.
It sounds like you board is not finishing the POST ( Power On Self Test) and this is usually caused by the ram stick or sticks or the CPU
Check them both with the boards specs.
Try leaving the memory sticks OUT and boot the board without them. If the board starts beeping, this is a sign of faulty sticks or incompatible sticks.
The length and number of beeps will tell you what the problem is ( but we already know that no ram is installed)
If this does not work, remove all the cards from all slots etc and try booting a clean board, if it boots, re-install each card one at a time until the card or ram stick which is causing the problem stops the board from booting.
Also, make sure your power supply has the correct power connectors for the board and make sure the ATX12volt connector is plugged into the board.
Some boards use a 20 pin power connector and a ATX12volt connector, newer boards use a 24 pin connector PLUS the ATX12volt connector.
If you are still stuck, I would suggest you take the case to a reputable repair shop. Poking around a live board can cause more faults then you can fix.
Make sure you have disconnected the mains from the supply BEFORE you remove or install any cards or board components. REMEMBER - modern boards all have a 5 volt supply rail connected to them as long as the power supply is connected to the mains!!!!

Have Fun

Assuming that you triple checked to make sure you made all the connections right ( and that the motherboard diagram is not actually printed upside down giving you a backward christmas tree line up for the pronged connections (which happens)... and that you did apply the heat sink insulater goop nice and perfect...and that all your stuff is compatible with each other..
there are two possibilities.
Either you got a bad motherboard or you got a bad power supply.

Good quality power supplies are equally as important as the mobo.
Swap out the power supply. If the problem repeats, its definately the motherboard.

Thankyou and good luck. Please remember to rate my answer *s*

Hello everyone. Just wondering do I need an optical drive for my brand new pic I just built? And I just installed my motherboard and the graphics card together but nothing is working on the screen.

use the cd that came with the mother board as it has all the drivers to make the mother board work and to line up the graphic card
if the was a cd for the card run that as well
other than that talk to a IT geek shop and get ideas

Msi g41m-p26 won start (no power)

The most likely solution is to replace any Capacitors that have blown in the onboard power circuit. Look for a Capacitor that has got a very bulging top in the region of the power connector.

Installed new motherboard, but system would not boot. What is the problem. Did not receive a manual with motherboard at time of purchase.

Hello Dch,

After replacing the mother board if the system is not booting up then check the power connections on the mother board. The wires of power, restart buttons are properly connected to the motherboard. Also check the thermal grease which is used between cpu fan and cpu. If the thermal grease gets dried then clean the grease and apply the 2 drops of new thermal grease and properly lock the cpu fan.

My ACER laptop will not switch on the workshop told me i require a new motherboard they installed a new mother board but the problem still persists


It is very possible that your battery pack may be bad. Even if it is holding a charge, the connector can go bad thus diabling your unit to power on. The workshop should have connected a voltage meter to the board to make sure it is working.

I would return it back to the shop and demand they correct the issue. (Assuming you paid them for the service.)

Good Luck.

No vedio

swap monitors if monitor is same dell brand then its the monitor. otherwise you can buy a Video card PROVIDED that you can disable from setup the MOBO video card, and install drivers, also speaking of drivers try uninstalling the video and monitor drivers first !! the do mon swap, finally new vid card .

funky things can happen to drivers, esp improper shutting down windows like flip a power switch or not having a UPS and computer shuts down during a power outage or storm. seen this happen as well.
