I swithed to asus crosshair motherboard. put in an athlon 6400 x2. Connected everything right. When i turn the power on, it stays on for just like 7 seconds then turn off. at the back the lcd says comp init. I also tried turning it on without the cpu, it works fine. tried my cpu with other mobo cpu runs fine. Help please

1) Navigate here and follow instructions to let it scan your system:

2) orhere to search for it manually:
http://www.nvidia.com/Download/index.aspx?lang=en-us

3) or if everything else fails download and install this one for automatic detection-downloading of drivers:

If everything fails, please report back!

sir, did you setup the motherboard to the cpu case all by yourself? tell me exactly what you did. thanks!

is this windows 7 32-bit OR 64-bit
you will need 64 drivers for all your hardware if you have migrated from a 32 to 64 bit operating system.
Windows7 64 bit still has some major bugs with certain sound cards.
Asus has updated drivers available at thier website, but they dont have them for all hardware, just the most current.
Hope this helps, post again if i can answer any more questions..
Regards!

get a pci card controller with usbs on it jim

no i dnt think so some time due to manufacturing defects this happens the new one wont burn unless and untill u over volt it.

Well, I would start by going to the ASUS web page and look up your specific motherboard. Here is the link right to the board---

http://usa.asus.com/products.aspx?l1=3&l2=117&l3=0&l4=0&model=1283&modelmenu=2

the specs listed at ASUS's site don't say specifically"how many Gz processor can my mothereboard suport" although they will point you in the right direction. Open up the site on a seperate internet page if you haven't already and look at if for me. Do you notice where it mentions the Socket types that it supports in the CPU section?? Basically the page is telling you what type of processors it will run. I believe the Athlon 64 x2 is the fastest out of what they have listed, although i did not look up the specs. You should be safe buying any speed Athlon 64 x2, Athlon 64 FX, Athlon 64 or Sempron processor. Hope that this was helpful, if it was could you please give me a good review? Thanks.

PLEASE INDICATE WHAT IS YOUR PROBLEM....

This sounds like an overheat problem, is your cooling fan working properly, also the processor you are using is a powerful one, so needs a cooling fan much more powerful than the lesser powered athlon 64 processors.

Make sure that your power switch is connected to the correct pins on the motherboard. The LED you see lit may be the stand-by power indicator saying it has power and is waiting for the signal from the power switch.

Hi Tomokato,
This maybe nothing but the first thing I checked is the CPU.
Supported CPU list through Asus web site for M2N-SLI
(Click on this link). http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=M2N-SLI
The first supported 64 X2 is;
Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2
Second CPU supported;
Athlon 64 X2 3600+ (DD),1MB,65W,rev.G,SocketAM2

The CPU that you are using is not supported.
Since this is a new CPU, you might be able to exchange it for the Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2.

Suggest you add the above link to you're favorites.

Even you're memory is not supported. As seen in user manual page. 2-13.

Have more questions, feel free to ask.
