AMD Drivers make windows not start up properly  

Do you have any errors or other(unknown) devices in Device Manager ?

could be a number of things

check power to the cables

check if it is in the slot all the way

those are things that would do that also check if you have onboard graphics interfering with your card

Yeah i did IT myself, i've checked and i'm sure i didn't move the computer or anything i didn't touch the hardware inside before i reinstalled it so everything is in place.

If your video card is not detected it could be a faulty card or your drivers aren't set up properly. What card do you have?

Sapphire 7950 OC

It simply does not show up in device manager.

Thing is i ran everything perfectly on my previous windows enterprise, but the key has been disabled so i not only had to reinstall the professiona one because i ****ed up some user account stuff in regedit and whatnot but also because it wasn't genuine anymore. Anyway, between switching from OS versions i didn't do anything intresting. I guess the videocard is just toast... will try to put it in a friends computer asap and see if it detects it to make sure it's no the motherboard.

Where did you get the current version of Windows and is it activated?

This is the one i still got from school, i downloaded it from MSDN or what's it called? And yes it's activated and genuine.

Can you post a screen shot of your Device Manager with the "Display Adapters" expanded?

It says "Standard VGA Graphics Adapter"

I also get a score 1 for (gaming)graphics in the performance index.

Can you try using the GPU in a different motherboard slot, or just re-seat the card in the current slot?
Testing the GPU in another PC is a good idea if that's easier.
