I say that it doesn't display the OS because it displays all fine during the start up. But as soon as windows starts, the picture goes away and the "HDMI no signal" message appears for some seconds before it all goes black.
Now the weird thing is that I still have a signal when I use the computer on the safe mode; it works with no problem. But when I try to tart Windows normally, the signal just disappears.
From that, I assume that it might be a problem with the controller and Windows 7, like it's not loading properly with the operating system. I tried to fix it using the safe mode, but I didn't really know what to do. I tried to update the controller, but as usual it says that the latest version of the controller is already installed. I accessed the startup programs but there was nothing about controllers during startup.
So I don't know what to do =(
My OS is Winos 7, 64 Bits
My Monitor is an ASUS VH236, LCD, 23 inches
My main board is a Gigabyte B75M-D3H
No video card.
