Hello,
It seems there is some external software interfereing on the video board communication. To help us identifying if this is the case, I would like to ask you to follow this procedure:
http://sourceforge.net/projects/hjt/files/latest/download
Please download the small executable “HijackThis.exe” and copy it to your computer desktop or some other convenient location. Run it as administrator, agree to the License that appears next by clicking on [Accept]. A small GUI with different buttons will next be presented to you. Click on the button [Do a system scan and save a logfile]. Please send us a copy of the logfile that is generated, “hijackthis.log”, as an email attachment.
“HijackThis.exe” does not install itself on your computer. You may simply close it and delete the executable file and it will be gone. This logfile lists every single process running on your computer.
Regards,
Gustavo.
