I have a Dell Inspiron 15 purchased last October. Windows 7. Have not installed any hardware, have not dropped the laptop or spilled anything on it. Last night I had it on battery power and it went into sleep mode while I was eating. When I pressed the power button to bring it out of sleep mode it brought up the login screen. After I logged in the screen went staticky with rolling pixelated sections of blue and black. Hit the power button, laptop turned off and back on, showed the Dell logo, brought up the login screen, then took a few seconds for the icons to show up on the desktop. I don't have a screensaver. Called Dell, rep had me run diagnostics, everything passed. He said it wasn't a known issue. Worked fine the rest of the night and seems fine today. Anyone else encounter this?
