Go to the start menu and type services.msc, hit enter.
Disable AMD External Events Utility
Disable Offline files (unless you actually know what it is AND use it)
Disable Windows Search service (everyone in the "know" does this)
The Lavasoft Ad-Aware might be contributing to poor game performance so you could uninstall that as a test. Especially because you're also running Microsoft Antimalware Service. Running both is not good. In this case, also
disable Windows Defender service. (You only should use one.)
Like I said though, visit ATI's site and download the latest driver
for the video card. You're running an older version 8.641 when latest is 8.671 - use the device manager to install if you need to, to make sure all driver files are updated.
