I am currently experiencing some problems with a PC and I am not sure if is it hardware or software but I am leaning towards software. It seems like the lower halve of the screen stretches sideways. It is a PC with two screens connected and both screens do it, I already replaced the graphics card, updated the drivers and that did not help. It is running Windows 7 Professional 64 bit and seems to happen even when not working on the machine. What can I look at to fix this? I attached an image of what happens.
