I have a Sony Vaio SVS131E1DL running Windows 8. Every time I boot the computer up it displays the initial Vaio logo, then the screen will flash from the logo to a blank screen and back every couple of seconds. I have tried removing the battery before startup, as well as reseating the memory, as those are solutions I have read in other threads. The computer is only about a year old. I cannot get use any of the function keys to access safe mode or any other screen. At this point I am unsure what to do. Any help would be appreciated.
