Dell inspiron 14z n411z, I have tried to install the intel hd 3000 graphic drivers from both microsoft and from the intel website. issue is occasionally screen will "flash" as in glitch sideways a little for a split second. I don't think they is any damage to the laptop itself because shaking it, or moving the screen open/close does not cause the screen to glitch up. it just happens completely randomly.
I just recently installed a fresh copy of 7 on a clean parition, but i think it had been doing it prior. maybe another driver or something i have installed is interfering with the graphics driver? I have tried re-installing random drivers, but it didn't have any effect.
