Neither the graphics driver nor the audio driver installed properly. And it seems that the wireless driver I provided is older than the one you already had installed.
If you wish to rectify these issues, try installing the graphics and audio drivers again. To revert back to the old driver, go to Start -> Run -> devmgmt.msc -> expand "Network adapters" -> double click on "Atheros AR5B91 Wireless Network Adapter" -> select the Driver tab -> click "Roll Back Driver". Close the dialog box after ensuring the version is "7.07.0000.0348", then close Device Manager.
The BIOS and chipset drivers were updated successfully. I can't be certain of the Ethernet controller's version, but that shouldn't matter much.
I'd say either updating DirectX and/or MTA:SA fixed your issue.
