As far as I can see, you don't have a copy of the ASACPI.sys file on your system in any position to cause any damage. No drivers by that name are loaded.
From the MSINFO32 report, you're missing drivers for these devices:
Not Available ACPI\ATK0110\1010110 The drivers for this device are not installed.
Xbox 360 Wireless Receiver for Windows USB\VID_045E&PID_0719\FD9B9BB0 The drivers for this device are not installed.
Multimedia Audio Controller PCI\VEN_1102&DEV_0007&SUBSYS_10121102&REV_00\4&35E69562&0&30A4 The drivers for this device are not installed.
Download this file from the Asus website for your motherboard and OS ( ASUSTeK Computer Inc.-Support- download_item_mkt
): ATK0110 driver for WindowsXP/Vista/Windows 7 32&64-bit It's under the Utilities section.
Extract the file to a location on your system
Double click on the MB Windows 7 ATK folder to open it
Double click on the 64 folder to open it
Double click on the AsAcpiIns.exe file to install the new driver
Then double check in the C:\Windows\System32\drivers folder to see if you have the 2009/2010 version of the ASACPI.sys driver.
I would remove the X-Box device from the system and uninstall it from Device Manager
I'd install drivers from the Asus website for your built in Audio device in order to make that functional.
Beyond that, I don't see any issues with your system - it should be working just fine.
Are you having problems?
