From what I have researched there are 3 main possibilities and ill list them from most likely to least likely.
#1 Your hard drive is failing or has failed to the point of not being able to boot in which case your computer will try to boot elsewhere and/or there is a problem with the connection from your hard drive to the motherboard. On most laptops you can easily unscrew a screw and slip the hard drive out. You may want to disconnect it, (with battery removed and ac power removed) then reconnect the hard drive to be sure it is securely connected.
#2 You have or possibly need a bios update which fixes this sort of issue. Only way to be sure would be to have your exact model number of Toshiba so that I could look it up for you to determine whether or not any exists.
#3 Your board is fried or some other hardware component on the board is. You would have to get the problem diagnosed.
There is also the mention that the CMOS battery could be dead and need to be replaced or removed to reset the bios entirely.
See these links for possible ideas and post the make and model if you can figure out what toshiba it is (or post the serial number on the bottom sticker or something).http://www.nocrash.c...msgs/3576.shtml
A post mentioned at geekstogo http://www.geekstogo...le-t184055.htmlhttp://www.computerh...es/ch000706.htm
What would I do?
#1 Remove and re-insert the hard drive.
#2 Reset the cmos if applicable and/or tell bios to change to defaults.
#3 Take the thing apart and check cables and else (usually laptop hard drives are plugged into a connector which is directly soldered into the board so in this case there is no cable to check.
#4 If all else fails and it is important to you, have a tech check it out at your local pc store. Have around $200 handy as you will usually be charged $50-$100 for the diagnoses + the cost of parts. If it exceeds $300, just sell the thing for parts and buy a new laptop as you can get a decent one these days for $450-$600
