Question about HP Compaq Presario CQ50-110US Laptop
I had this problem on a certain brand of laptop,i finally refered to the owners manual to find FN-F5 toggled from the screen to external monitor depending on 1 click or 2 etc and that Fn-F1 put the screen into sleep mode the same way---im not suggesting your machine uses the same sequence keys but it might be worth a try finding out if you have accidently toggled your keys.
you could also be missing your OS or your bios boot sequence is incorrectly set--Press F2 whilst booting to get into boot sequence option of bios)-there navigate with tab or arrow keys--save and exit or reset settings to default and exit--dont change any thing in bios settings until you are familiar with how to navigate and select changes OK!

Turn on your laptop and look at the first screen that comes up as soon as it is on. This screen will tell you "Press x key to enter setup", replacing "x" with the actual BIOS access key. It's usually "Del" or "F2" on Toshiba systems.
Press the key firmly and quickly before the screen goes away. If you do not react quickly enough, you will miss the window of opportunity to enter the BIOS. On Toshiba systems, this window of opportunity is somewhere between two to five seconds.
Navigate your BIOS configuration screen to the "Boot" tab. It is usually just before "Exit."
As the first boot device, select "USB," or "USB HDD." If you have a "USB ZIP" option, you might be able to boot from it, so select that if you have no other choice.
Press the button for "Save and Exit" in your BIOS. The correct button is usually F10.

test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) Ide/Sata make sure they have a secure connections and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?
even something as small as an electrical extension or a faulty fan lead can cause this problem
a computer needs all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly
make sure your graphics card is securely seated with no dust in its socket
