Hi I find out that my "Intel(R) Management Engine Interface" shows the problem in system profiler.
In properties it says "This device cannot be executed. (Code10)" - its just free translation
Driver has date 17.9.2009 and vesion 18.104.22.1689
I have Win 7 64bit
motherboard is Gigabyte H55M-USB3
How can I repaír it or reinstall it. Where I can download and update. I couldnt fint it on Intel site.
