Hi swindoro,
I am sorry to hear you are having problems with your system but let me help you.
Based on the information you have provided, I recommend you uninstalling the current driver graphics from Device manager and install the latest one from our side. Here you have the instructions:

You can download the latest drivers at the following link:

Besides this step, I recommend installing the latest BIOs updates and drivers from your computer manufacture. Please be aware that I have tested a system with HD 2000 and I was able to load the Media Center on Full screen mode and played some videos and music without a problem.
I also would recommend searching for an update for MC or running the Windows Update.
