Hello, I recently bought a new HP Pavilion desktop with Windows 7 Home Premium factory installed and installed some of my old games on it. Well, for the past week or two I've had this rather annoying problem where I leave my computer on for an hour or so, come back, wake the computer up only to find that all my desktop icons and toolbars are gone, leaving my desktop background completely bare. Another thing that I find strange is that bringing up the task manager makes the screen turn black. So far I haven't found anything of any help over the internet regarding this problem. Any help would be appreciated.
