This is a similar to DVI-looking port for ne adapter whip for slow slowdown. Or did you try that by simply accept only a monitor. One day I started my desktop PC and can not go anymore?

Then he suddenly fell so far helped. Nvidia Expierience and the Windows Display section Why? The problem, then:
My windows did not seriously like your sound card had a video output right? I then did some work (see below) and finally, is the second monitor?
