I have a toshiba Satelite L505D-GS6000 and this morning I was surfing the web and my laptop just shut off. So I thought that maybe it unplugged so I started it up. When it started up it was all normal but after it had the screen with the "Toshiba LEADING in Inovation" it went to a black screen with a blinking DASH to the top left and every time I click a button it beeps. When I click Ctrl alt Delete it goes back to the "toshiba leading inovation" screen. How do I fix it. And by the way I do have a RECOVERY disk but it wasnt working when I tried it. PLEASE HELP!!!!HARD Drive Crashes can cause this and for recovery disks to fail. If the HD is bad, the recovery disc's cant USE the drive to perform repair or clean install. I'd suspect the hard drive if it is not happy with bootable recovery CD/DVD.Disregard the above post.

Reboot. As soon as the system begins to boot start tapping the F8 Function Key. That should take you to the advanced boot options screen. From there, try "Last Known Good Configuration". If that doesn't work, try Safe Mode. Any luck with either?
