OK, get the chipset drivers from here: Foxconn Support - Download
Scroll down until you see "Motherboards : Socket 1156 : Motherboards Drivers : System & Chipset Drivers" (it's the 4th one down)
But, I'd like to find a more recent chipset driver for you, so try this:
- download and install CPU-Z (free from here: CPUID - System & hardware benchmark, monitoring, reporting
- click on the mainboard tab and read what it says for chipsets there (north and southbridge)
Foxconn says it's the Intelо H55 chipset - but I'd like to be sure so we can download it from the Intel website.
To find out if the SlimDrivers program worked, go to C:\Windows\System32\drivers and check the dates on the files from above.
Since you've uninstalled Microsoft Security Essentials, it's not likely that the MPFilter.sys driver will need to be updated (unless it's also being used by OneCare or Windows Defender).
The amxdata.sys driver is in the chipset drivers that I described above.
Uninstall the Intel Turbo Boost program for now. If needed we can find another copy at the Intel download site.
Please let me know what you found (if anything) in Device Manager.
