what sort of error message does this come with?
or does it just fail to load the OS, if so it might be a case of reinstalling windows (if you use that)
to make sure you don't loose your files build a knoppix live CD/DVD/USB (plenty of guides to help you with this) once you've done this go into the BIOS and change the boot order to whatever media you have it installed on to first so lets say USB it will look sort of like
4. Network Boot
so once it boots navigate to the HDD and you should be able to access all files now just begin copying the ones you want to keep
The HDD password is a BIOS function. A password is set and passed to the HDD. Then the BIOS on power up sends the password to the HDD and unlocks it on each boot. It could be your HDD is dead and so when BIOS sends pwd to HDD there is no response.Try BIOS reset to defaults
Remove the hdd cover from the bottom and make sure it is completely seated and connected. If the hdd is properly installed and it still will not boot, try entering the CMOS Setup. If you can enter setup you most likely have a bad hdd. If you can't you need to take or send the pc to a repair shop.
Shutdown the system and disconnect the power cable.Disconnect external peripherials.Hold the power button for 10 secs to drain static power.connect the power cable to the computer.turn on the computer and hit the F2 key to boot in bios.If you are in the bios turn on the caps lock,scroll lock, and numlock key.then Hold the Alt key + E, then Alt key + F, Alt key + B. Computer will restart check for hdd or boot device.If hdd is detected it should boot to desktop.If issue persist .Shut down the system.disconnect power cable.Hold power button for 10 secs.Open the tower and disconnect the hdd from the sata or ide cable.Connect hdd in a different sata or ide connector.Connect power cable and turn on the computer and follow steps 1.If still getting same error possible hdd gone bad.Good Luck.
Either the power supply is putting out too low voltage or the power jack is bad.Try moving the ac adapter tip around while its starting up to see if it keeps it running or shuts it off.If it makes no difference try another ac adapter that does work for sure and see if thats the problem.If neither approach works,then the HDD may be seizing or one of the ram sticks may be bad.Some sort of hardware conflict can cause shut downs.You would have to take the bootstrap approach to narrow it down to one pacific component.
-Take a look in your BIOS console to see if your primary boot device is connected and shown in the list.
-if yes then, bootsector on primary boot device is missing, and you might have to connect this HDD to a different computer and back your data up, and then connect it back to your computer and run the windows recovery. make sure you scan for bad sectors after your system is up and running.
-if no, then shut your computer off and groud yourself and take all the precautions for static and open the cabinet and make sure that your primary boot disk is securely connected to the motherboard and power connector is firmly connected to it (you can try switching the cables to see if its an issue with the cables, motherboard ports or power supply)
The flashing caps lock is an indication of a failed POWER on Self-Test (POST)
Remove the HDD, Battery, AC adapter, RAM and Modem
Press and hold power button for 15 seconds
Connect AC, see if you get any beep codes. If you do, power off, disconnect power, insert RAM, connect AC and reboot. If system boots, power off and add hard drive. If it doesn't, replace the motherboard.
If the system boots with RAM, but fails to boot with HDD, replace HDD 1st.
