Hi, everyone.. I just joined the community cause I'm having a serious problem with my Lenovo desktop, and I BADLY need help recovering some data. Just recently, when I booted up the computer, the monitor displayed the Lenovo logo, then displayed that it was troubleshooting, then the screen went blank. I've rebooted a few times now, and there is less and less time before it goes black, each time I reboot. Now, when I reboot, it just displays the Lenovo logo, then immediately goes black. But I know it's still on, because when I put it in sleep mode, then exit sleep mode, there's a password screen that displays for about 2 seconds, before once again going black (fully black btw -- no cursor, no NOTHING)... I don't know a whole lot about computer machinery itself, but I am a bit curious as to whether it has something to do with the fact that, when I boot up the computer, I hear the machine's fan going, but it shuts off right before the screen goes black. I generally fix these problems by Googling and researching, because I hate asking others for help, but I really do need some advice here... Can someone please offer up an idea? Thank you so much!
