Graphic problem at the startup

[Cionny]

Hi Guys, first of all I'm Italian, so I'm sorry if my English isn't the best, hope you'll understand

I've recently done my first hackintosh, here's the configuration:
Motherboard: Gygabyte GA-Z87X-UD5H
CPU: i7-4770k
Ram: Crucial Ballistix Tactical Tracer 1600 8GB (1x)
No graphic card (I use the integrated one)
SSD: Samsung 840 Series Pro 256GB
HD: Seagate Barracuda ST1000DM003 1TB
Power Supply: Corsair RM650
Case: Corsair 500R
OSX 10.9.4
DVI Connection

Here's the video of the problem ... During the startup something goes wrong (0.13), the Apple logo goes away and then appear a "lag" screen. After few seconds the Apple logo comes back and everything works fine:

Are you using the native resolution for your monitor? If not, set it to your native resolution to prevent artifacts.

Yes, I'm using it, I'll check it anyway (at the moment the pc is at my friend's house).
In addiction, down in the "lag" screen, there is the last screen that there was when i shutted down the pc; in the video, in fact, you can see the dock and the desktop background. Yesterday i shutted down with the finder opened, and down in the screen there was the window of the finder.
I hope you'll understand, thanks!

On wich port is connected your screen? Dvi or vga?
Did you try other symbios?

My dear Friend justo do this:
Change you Sys Def to : iMac 14.2
Boot.plist: IGPlantform : 0C260000

Those change fix my same issue
