I have an asus M4A78LT-M LE motherboard on a amd athlon 2 x3 440 processor and nvdia gt 240 gpu. The problem i am having is whenever i start my system 4 dialog boxes pop up telling me to install high definition audio bus. The device manager in control panel also shows 4 yellow question marks beside audio device on high definition audio bus. i am using a windows xp service pack 2 OS and VIA HD audio driver. please help me on how to get rid of this problem. THANK YOU.

Hello here is the homepage:

To enable crossfire, you must have 2 identical graphic cards.

The onboard graphic can`t be used with the hd6670.

This means that you must buy another hd6670 to add on the mainboard.

The graphic cards homepage:

http://www.asus.com/Graphics_Cards/AMD_Series/EAH6670DI1GD3/

AMD CrossFire technology is the ultimate multi-GPU performance gaming platform. Unlocking game-dominating power, AMD CrossFire harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve gaming performance.

You also need a large power supply min. 500 watt to have enough power.

Please disable the onboard graphic in the device manager.

Good luck

all you need to do is go to asus web site look at am2+ motherboards and see what you want just that easy jim

No, you do not need a video card because that motherboard has graphics integrated on the motherboard. The motherboard has the following video processor built-in:

Integrated ATI Radeon™ HD 3000 GPU

Feel free to let us know if you have further questions.

Thanks!

Hey there. Your motherboard is most likely faulty and is causing shorts inside the keyboards and mouses. You should get a replacement from your retailer for the motherboard.

Have fun :)

Click here to view the list of supported processors for the ASUS M4A78LTM LE Mainboard.

The AMD AM3 Phenom 2 X4 965 3.4GHz is not supported as it is a 125Watt or 140Watt Processor.

The ASUS M4A78LTM LE Mainboard supports up and including a 95Watt Processor.

Therefore you either need to downgrade, purchase a Processor that is supported as shown in the list or purchase a Mainboard that supports your AMD AM3 Phenom 2 X4 965 3.4GHz Processor.

I myself would go for an ASUS M4A88TD-V EVO/USB3 Mainboard, its a good companion for that monster of a Processor you have got.

See if you are able to return the Mainboard and purchase the ASUS M4A88TD-V EVO/USB3

There is also the cheaper ASUS M4A785TD-V EVO

Tell me how it goes!

All the Best!

the only phenom-II cpu's it supports are the 545 and 550 socket am3 1.01ghz. if you have anything other it will not run. here is complete cpu support list here

This are the comptible processor that you can use for this motherboard if you plan to do a upgrade on it. AMD Athlon 64, AMD Sempron, AMD Athlon 64 FX, AMD Athlon 64 X2

Here is a link that contain all the details about this motherboard.

The ASUS A8M2N-LA is the motherboard used by HP for the new D4500e AMD AM2 PC.

Here are the details:
Motherboard manufacturer's name: ASUS A8M2N-LA
HP/Compaq name: Nodus-GL8E
CPU/Processor
Socket: AM2 Supports AMD Athlon 64, Athlon 64 X2, and Sempron processors
Front-side bus (FSB)
2000 MegaTransfers/second
Chipset
GeForce 6150 LE chipset
BIOS features
Award brand system BIOS Keyboard combination to used to enter BIOS: F1
Form factor
Micro-ATX: 9.6 in X 9.6 in
Memory
Four 240-pin DDR2 DIMM sockets, Supports PC 4200 (533 MHz) and PC2 5300 (667 MHz) DDR2 DIMMs, non-ECC memory only, unbuffered Maximum HP/Compaq approved memory is 4 GB*
PS - as you can see the rangeis 533 - 667 MHz. I would suggest you call HP support and ask if it will support 800 MHz,

The Ol' Asus A7V266-E?
1.The fastest Front Side Bus setting is 266MHz
2.Uses Socket 462 AMD processors
3.Uses Athlon, Athlon XP, and Duron AMD processors.

I would stick with an AMD Athlon XP. Fastest one? Hmmm, I believe that would be the AMD Athlon XP 2600+
The one that operates at 2133MHz with a FSB of 266MHz. Part number AXDA2600DKV3C

Here is the Motherboard Manual for your Asus A7V266-E, (It's a PDF file download. Let it download all the way before looking through it)
http://www.motherboards.org/files/manuals/1/a7v266e-100.pdf

If the above direct link does not work for you, then go here,
http://www.motherboards.org/mobot/manuals/ASUS/A7V266-E/ (Click on -> Download <- all the way to the right of -> File:a7v266e-100.pdfVersion:--Release Date:--)

Go to Page 19, Item 2. NO POWER connected to computer, make sure the SYSCLK (System Clock) DIP switches are set to 133MHz.
1, 2, 3, and 4 are set to the OFF position for 133MHz.
All you will see is the ON. The switches go to the opposite side as shown in Item 2.

I'm sure they are set there however, as your 1900+ you have in right now, uses a 266MHz FSB.
I should explain.
AMD processors are Double-Pumped. Therefore the 133MHz setting will become 266MHz for the processor. (Intel processors are Quad-Pumped.

They are both the same Core, (Thoroughbred A/B, Model 8, 130nm), so a BIOS update shouldn't be necessary.

1. goto Bios setup diable your onboard display
2. get a new display card and its driver, fix it in
your computer.
3. install the display card driver.
4. your problem will be solved.
