First of all I would like to say that this problem has been looked at by 2 computer repairing services and both of them failed . I have asked on 2 forums already without even getting any answers, but I am convinced that there is a solution to my problem.
I wasn't sure if I should post this problem here or as a windows 7 thread however the origin of the problem comes from a hardware issue yet I believe that a solution can be software related.
Going to try to describe my problem as simple as I can so I might skip important bits which I can fill in if anyone bothers with reading and will be willing to help.
So I am the owner of an alienware m17x R3 laptop which graphics card (nvidia 560m) started to die last year (white screen + freezing) and re flowing couldn't help it. I was advised to buy a new graphics card and so I did buy a nvidia 870m. In the beginning there were some troubles with drivers which I solved by changing few inf files and I got my card to work. All of this was done on a old system which was installed on my old graphics card and only the video drivers were removed. Few months ago I decided to clean my hard drive and install a fresh copy of windows 7 (got original disc). Here is where the problem starts. The installation of windows is going on without troubles and everything is displayed fine until the installation is finalising its operation. Then the system restarts and whenever it starts again it loads into white screen (no cursor or anything). Services which tried to fix this used different versions of windows and install paths (through flash drive etc) and even difernt HD however the same problem keeps coming. I am not even able to open the system in safe mode because it says that it cannot finish installing windows in safe mode. I am pretty sure the card should be working fine since the moment laptop stopped working was when I uninstalled OS (deleting all drivers) and my personal theory is that there is something in the laptop that does not accept the non-default GPU.
Not sure if anyone here will be able to help me, but if there is someone to try to deal with such advanced problem I can try giving more info if required.
