I mentioned earlier about the installation of the AMD USB filter driver (even though not an AMD system). DO NOT install it if you run an Intel system! All seems fine for a start, but after the computer was in standby for a while it did not wake by keyboard or mouse (both USB). This is the first time it happened. I also have a USB connected hard drive. When I shut down the system the USB drive kept running, and the system 'froze' on boot (trying to initialise the hard drive, after a minute or two it 'booted') but the drive wasn't available in Windows. I uninstalled the USB filter drive and everything back to normal now! It's only 'available' due to something with the driver modding, it's not Asder's fault or anything . Just thought I'd make people aware that you need to manually deselect it for all non-AMD chipset systems. Also, as someone mentioned the ACP utility is for TrueAudio, if you don't have it, don't install it! (or select to uninstall it).
