For a few days, my GTX 460 gives me problems. Sometimes, the image moves radomly left and right. This goes very fast but is very annoying. After that, it moves back to center and it also moves about 2-3cm. This morning, my computer started and the image was already moved 5cm to the left. I had to change framerate/resolution and then change it back to fix it.
Sometinmes, my screen gets blurred and this can only be fixed with a restart or with changing framerate/resolution and changing it back.
My screen: Link (sorry, not on the english amazon)
My System: Windows 7 Professional x64
How do I fix this?
