It might be a sofware issue "windows", since you have your machine do what yevrag says please.
It would be nice to see what cpu-z says about hardware mainly in the gpu tab section.
Also since you got this working in another computer please tell us what you did to install it and get it working.
Also "what" drivers did you use or what is it windows generic drivers installed by the os ?
I know its alot of questions buts that how I work, the more accurate info the better chance of this getting fixed sooner.
