Problems on Windows 7 64x with DirectX

[static_anachromatic]

Hello! :D

I am having a MASSIVE problem with this game, and i hope you can help me.

When i first tried to run it, it completely locked my pc. I had to hard reset it.

Then i went into the HitmanBloodMoney.ini file and changed the resolution to 1920x1080 (my native resolution)

Now i can start and play the game, but when i press alt-tab or exit the game, my pc lock up again.

My PC is a MSI GT70. http://www.msi.com/product/nb/GT70-0NC.html

I have tried to download a few different DirectX installers. Mostly old ones (2009-2010), since people say that they may install some missing DLL's that can solve the problem.

Now, the thing is, when i try to run those installers as administrator, It says: An Internal System Error Occurred.

I have tried the newest DirectX installer, (the one that looks for missing files and then downloads the missing files automaticly), but it just says that a newer or equivalent version has been detected and does nothing.

Sounds like the problem is either with the system or the NVIDIA drivers.
