El procesador es Intel G860.
Bear in mind our support is in English only.
I recommend you uninstall the graphics driver from Programs and Features in Control Panel first and then install the graphics driver from this link https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22519&lang=eng&OSVersion=Windows%207%20%2832-bit%29*&DownloadType=Drivers
If the issue persists you can try updating the BIOS of the motherboard from this link http://www.gigabyte.com/products/product-page.aspx?pid=4089#bios
You can also run a test to the processor using this utility http://www.intel.com/support/processors/sb/CS-031726.htm
Thank you for help me.
After installing and checking all of the options was the same problems. Replacing the motherboard of the new solved the problem.
