I recently upgraded my AMD Sempron system to an Anthlon64. Before I replaced the CPU, I had an installation of Windows Vista Home Premium that worked flawlessly. However, ever since the CPU upgrade, Vista keep detecting the following error:

PCI-Express Standard Root Port (Code 12)

I know Code 12 is a resource problem, and I have tried to disable other devices on my system to attempt to fix the problem. I have had no luck.

Here are my system specs, if they help:
AMD Athlon64 2.8GHz (2MB Cache)
330GB HDD (SATA2)
2GB RAM
NVIDIA G100 (GeForce 9400GT)

If anyone has any suggestions that could help me fix the problem I would be extremely grateful, as I do not really want to do yet another clean install of Windows XP.

Regards,

Bee

I assume that you did the Vista install after the upgrade.
Did you reinstall the system drivers?

No. The installation was existent before the upgrade.
I did install all the MOBO drivers, and I also tried installing the Video Card drivers, but it says the specified hardware could not be found.

If this helps, my MOBO is an MSI V-Class K9n6PGM2 with the nForce430 Based Chipset.

Let me get this straight: Your install was working properly. Then you removed the existing CPU and installed a different one. Now it is not working properly.

And we are to believe that somehow this is the fault of the OS? I think not.


With that settled, here's some things you can do about the situation you created:

First - Are you *sure* your current Bios version supports the new CPU???? Make sure.

I'm positive.

I have Windows 7 BETA on a different partition (using now) and everything works fine.

You will probably have to do a repair install of Vista. It may contain different parameters for the better CPU.

Didn't work.
At least it didn't create any MORE problems, but I just don't know what else to try. I re-seated my sempron last night and the OS started working and functioning correctly again.

It has to be something to do with my new CPU, but I can't think what. I have done a few Google searches and discovered there are a lot of people having the same problem with the nForce chipset(s).

I also tried to download the latest drivers from the Nvidia website last night, no luck. I flashed my BIOS, no luck. I don't know what else to try.

I dont think it is the nforce chipset because that is what I am running.
What are the specs of your computer?

Vista = PROBLEMS.

Solution: Dump it.

Last poster = NO HELP.

Solution: Ignore him.

If you don't have anything you need backed up, I'd suggest wiping the Vista partition and installing it clean. If it boots successfully, then there is some piece of software or driver causing your issue. Can you boot into Safe Mode?
