Build and Shoot

Hello fellow mappers.

I know that not many of you use Voxed (the map editor included with both of the 0.76 and 0.75 versions) to make maps, but I want to use It to polish my maps Instead of loading them in-game and spending hours tweaking them only with a spade and some blocks.

The thing Is, whenever I try to open Voxed.exe, the screen goes white for 5secs or so before loading the map. That's not it ; I'm running Voxed at 2fps (I can't even look around or move the camera).
That's still not it ; It crashes my video driver after 10-15 secs most of the time.

And It worked just fine before I reinstalled Windows (Took a nice rootkit right in the face).

Here are my specs (custom built !) :
i5 3570k 4.2ghz (4-core)
nVidia GTX 660Ti (2gb GDDR5, MSI)
8gb DDR3 (4x2)
1x 120gb SSD (Samsung, my OS Is in there !)
1x 500gb HDD (Seagate Barracuda)
1x 150gb HDD
Windows 7 Ultimate x64

Any help will be GREATLY appreciated.
If you need any supplementary details, just say It.

Thanks lads !

And BTW, It works just fine on my laptop. I must be missing something that's required on my computer.

Also, I'm trying to Install a 2013 driver for my graphic card.
Slab6, Openspades and Ace of Spades voxlap are running fine.

PROBLEM SOLVED !
Reinstalled old GPU drivers, works like a charm now.
