NVIDIA GTX 960m's problem

[hamed]

I bought a new ASUS n551vw Intel(R) core i7-6700HQ CPU 2.60 NVIDIA GEFORCE GTX 960m.

I have a big problem with my graphic card (I guess), the problem is that when I start using chrome, firefox and..

other web browsers the font change to an awkward form that I have never ever seen in my life as it is shown in

in the photo below!

Is there anybody who has the same problem ?

This doesn't look like a graphical corruption, it looks like a type font, the GPU doesn't decide on type fonts. The problem is software based.
If you have been testing out themes that could be the answer. If this has been happening from the start then your system may be missing some font data. If neither of those I would do a full malware scan.
