Recent Hardware Changes. Corrupt drivers for any recently installed hardware can crash the system. To get rid of the corrupted drivers, do the following:

a. Uninstall all recently added hardware.
b. Try to restore the system to a previous restore point
c. Reboot the system and return to a previous stable configuration if possible
d. Remove all external peripherals (printer, cameras, scanners, etc) and connections until the computer returns to normal.

BIOS - the Binary Operating System may be corrupted - Use of Safe Mode to boot system.

a. Try starting the computer in the safe mode. Restart the computer and see the point to which it boots up before you get the blank screen.
b. Press F8 as the computer starts to boot. (For HP and Compaq computers with VISTA, use F10, For HP Pavilions with XP or earlier version of OS, use F1). Use the arrow keys to select the safe mode and press Enter. Remember that NUM LOCK should be OFF for the arrow keys to function.
c. If Windows launches before you can choose the safe mode, restart computer and go to step a.
d. You can choose "Safe mode with command prompt" option if you know how to use MS-DOS
e. You can choose "Last known good configuration" to go back to the last known safe shutdown state.
f. If you have added any drivers or corrupted any files the last time you used the computer, the safe mode will help you get back to the state before the changes, when the computer was running smoothly.

Hard Disk Crash. This is one of the major reasons for black screens. A new computer will run reasonably well for about 2 - 3 years. After that, we'd better take precautions to manage our information in case of a disk crash. Backups are handy in case we need to re-install or replace a hard disk. To check if it's the hard disk, do the following:

a. Turn the computer on and listen to see if the fan is running.
b. After doing all the checks above to see if the peripherals (especially the monitor) are in good working condition, restart the computer again

Motherboard Problems.

a. Open the chassis. Turn the computer on and verify that the CPU fan and the power supply and the fan are running. If not, make sure that the connections are tight and replace the power supply.
b. Shutdown the computer and let it cool down. Unplug all cables from power sources.
c. Closely examine the mother board and see that it is NOT in contact with the computer case.
d. Removed and re-install your DRAM
e. Remove the CPU and re-install it.
f. Reset your BIOS to the default configuration following the motherboard's manual instructions.
g. Make sure that you have replaced every item that you had removed from the chassis, close it and try to start it up
h. If none of the above works, its time to seek professional help!
