Hi and welcome.

The major issue is the athrx.sys driver, for your Atheros wireless lan.

Check the device manager for the exact type you have, then update it from here:

0: kd> lmvm athrx
start             end                 module name
fffff880`040a7000 fffff880`041ff000   athrx    T (no symbols)           
    Loaded symbol image file: athrx.sys
    Image path: \SystemRoot\system32\DRIVERS\athrx.sys
    Image name: athrx.sys

You also have a very out-dated Marvel Yukon network driver:

yk62x64 yk62x64.sys Mon Feb 23 10:02:27 2009

Visit Sony's site to download and install the update to it.


Update this from Sony's site.

While there, you must update the Sony Fimrware Parser Extension driver which has issues:

SFEP SFEP.sys Fri Aug 03 01:35:53 2007


While there, also update your Ricoh SD Card Reader driver:

rimssne64 rimssne64.sys Wed Jul 08 04:24:39 2009


And it is also very important to update the NVIDIA video driver while there too:

nvlddmkm nvlddmkm.sys Mon Jul 27 20:41:15 2009


And it is also very important to update the Intel storage driver from Sony's site:

iaStor iaStor.sys Thu Jun 04 21:53:40 2009


Update your Realtek HD Audio driver from this link. Run it, reboot then run it again:

Thank you for your help! I'll be here again after all updates are finished.

Just as I predicted this was going to be a complicated process.. Drivers are not being updated, well that's is what I see in Device Manager. Whenever i attempt to update any of the drivers and check the driver information the date remains the same as before the update. I assume this is because It is a different version of Windows 7 and there is a conflict.

Versions do not matter, besides the architecture. What that means is that all drivers for Windows 7 work on all versions, as long as if you have 32 bit you install 32 bit drivers and if you have 64 bit, you install 64 bit drivers.

Update like this in device manager for the Atheros. First, extract the download to a folder. Then right click in device manager, choose Update driver software. Browse my computer. Let me pick. Have disk. Browse.

Now find and double click the .inf in the extracted folder. Hit ok then next and it will install. All other drivers will have a download .exe to run and update automatically.
