I recently read in small problem with my computer, the graphics card drivers latest Nvidia crashes with Firefox, the same happens with older or beta drivers. I can not tell me what it is, it is page-independent, factorial, however, that about every 20-60 min my screen turns black and then comes the message: I now know that freeze my computer, no BSOD no nothing. The last freeze, my mouse cursor still changed from the standard point made in the Windows loading sign and the image displayed on my motherboard but freeze A deep prolonged beep.
