No Graphic card under display adapters.

The properties of my only shown display adapter are: Intel(R) HD Graphics 3000, hardware id =
PCI\VEN_8086&DEV)0116&SUBSYS_04CA1028&REV_09
PCI\VEN_8086&DEV)0116&SUBSYS_04CA1028
PCI\VEN_8086&DEV)0116&CC_030000
PCI\VEN_8086&DEV)0116&CC_0300

Someone?

I booted with linux lime(something) a while ago, and sadly also there it didnt find any devices.

That's one argument more for the "it's not a Windows problem" list.

I could write down the hardware id's 1 per 1, but i wont know what it means...

When you have the hardware IDs, all I do with them is put them into Google and see, what it is. That's all I do to find out. The ID you posted above belongs to an Intel HD graphics card. You can try that with the elements in the device manager, of which you think they are somehow strange.

There are people who fixed this trough changing registry keys from 0 to 1. (i dont know what it means, but they say it works for some people) I'm just too scared too brick it totally.

That means that they changed a value inside the Windows registry. There is no need that you do something like that now, but if you still have the website where someone writes that doing such a change helped him, I can have a look at it...

A stupid question: have you tried running the driver installer for the nVidia graphics device? I don't recall reading that you explicitly did so.

You may get a "no nVidia graphics card detected" message or something of the sort, but it should do no harm.
