Hi guys! There is sometime I have a huge problem: I can't update nVidia drivers! If I try to update, my Windows initialization files corrupt. My machine configuration is: mobo Asus P7P55D Deluxe (using modded bios version 2003); video EVGA GTX 470; 8 Gb RAM Corsair XMS3 DDR3 (CM3X2G1600C9). I'm using Windows 7 64x. I don't know what may be happening: I tried fresh installs, extract and install the driver manually, install the driver through Windows Update, but nothing works: everytime I'm installing the driver, my system hangs, and when I restart the computer Windows don't load! I must use the system restoration or the initialization repair to bring it back, and sometimes it don't work too, and I need to do a fresh install; this happens with any driver above 296.10, the latest that works to me. Some tip, idea, or pray? Thanks in advance, and please forgive the English errors, I'm Brazilian and don't write well in English!
