You need to read the part about pixel clock limits. Since you're using an HDMI adapter, the HDMI limits apply. You won't be able to get 90 Hz with HDMI, and that monitor probably won't be able to handle 75 Hz over a single-link connection. That monitor requires dual-link DVI to get higher refresh rates.

That means the driver is restarting, so the error is coming from an external source. It looks like igfxColn_v4229.dll is coming from Intel's integrated graphics driver, but that shouldn't even be enabled if you have a dedicated graphics card.
