big trouble with Athlon 64 X2 3800+/Asus a8n-sli premium

[captain herisson]

hello this is my first post here

To be short, winXP pro sp2 detect only one core of my X2 and run only with "standard PC" HAL.

i have the latest stable bios (1009) and the latest cpu/mobo drivers.

the full story : i have updated my pc by changing the motherboard (k8v/kt800 -> asus a8n-sli premium) the cpu (3000+ -> X2 3800+) the CG (9800pro -> 7800gt) and the ddr (1gb PC3200 -> 2gb PC4000).

Because i'm keeping my windows installation i have changed my cpu to "standard PC" in the device manager and followed the process described here : http://www.ngohq.com/home.php?page=Articles&go=read&arc_id=36

After booting the new pc i had a lot of trouble, usbs didn't worked, the optical drives had some trouble refreshing and i could not change my cpu to ACPI monocore or multicore, i had two "standard pc" at this point...then i have installed/uninstalled the chipset and cpu drivers many times and tried a lot of things and still no luck.

So i decided to repair my windows installation using a slipstreamed winXP pro sp2 ... and after the reboot, BSOD while loading
i have tried again but this time forcing (using f5) ACPI Multiprocessor PC and ... BSOD
then again using ACPI Uniprocessor PC ... BSOD
and Advanced Configuration and Power Interface (ACPI) PC ... BSOD

so finally i chose standard PC, and that worked fine but still only one core is detected - one standard PC now, the optical drives don't refresh.. only the USBs are back to normal.

i'm totally stuck :/

btw cpu-z give the right info about the cpu and comfirm that i'm using the "Asus a8n-sli premium ACPI bios revision 1009"

Update to the 1011.001 beta BIOS. It's stable and it works properly with dual core CPUs.

ok i have updated to 1011.001 beta BIOS and because i was still unable to change "standard PC" to anything else in device manager i have repaired my installation and... BSOD, so i repaired again forcing standard PC HAL (f5) and now windows go to the second step of installation but hang at "device detection" maybe because of beta bios, i have no idea..
i think i may have a defective motherboard mh ?

Just format windows, it doesn't look like a mobo but a software problem to me.

Did you reinstall Windows after you put the X2 in, or did you just pull an old processor out and pop the X2 in?

If all you did was replace the processor, you'll have to reinstall Windows.

Suck it up and reinstall Windows, you need a new kernel for dual core and I don't think there's any way to get it other than doing a full reinstall.

You can reload the HAL within Device Manager, and change it to ACPI Multiprocessor by simply doing a new hardware scan, although windows should automatically do this anyway. With my 165 it worked straight away no problem, I only reinstalled when I corrupted the OS. However this can become troublesome and may not always work (Hasn?t always worked for some people), so reinstalling is always a sure way.

thanks guys reinstalling did it \o/
the funny thing is i did the "repair method" successfully to a friend in the same situation Oo

sorry for the reply delay but i had a lot of trouble for surfing especially filling forms, i just found it came from cool & quiet (i had speed issues too) that's weird.
edit- now that's fixed
