While in a site, facebook, google, and looking at a page, it will start to flash on/off and then go blank. By this, the heading of the page shows, but none of the information I was looking at. Seems the window freezes. I can try to shut the window down with the close screen red X in the top right conor, but nothing happens. I have to turn the unit off with the power button and reboot it, then it works for awhile, but will fail again shortly. I have a XPS13 Dell, about 4 months old. Any suggestions or help. Thanks, Norm
