if i am using youtube, as i change the video, screen get black or if i open new window, more time screen black some time message appear "display driver stoped now working". sometime show memory dumped. and restart again.
I just have to let you know it's LAPtop. Not lab top. That's like my first pet peeve. I tell you this so you don't say it to someone and look stupid. I would try installing latest video drivers, or reinstall windows
