Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty
If its a 40 pin flat ribbon type it will be the first to fail.
Even something as small as a faulty electrical fan and its lead can cause you problems
computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error.
Make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free.
Restart your computer then reinstall it this should activate found new hardware wizard
Check the VGA cable connection running from the computer to the monitor.
This cable must be completely inserted into both VGA connection ports, otherwise the video signal is not going to reach the display.
Disconnect the VGA cable from the computer and monitor, then look at the metal connectors on both ends.
If you are missing connection pins, the video signal is not going to transfer between hardware correctly.
Examine the power connection on the monitor.
If the monitor is not receiving power, it is not going to turn on.
Turn off the monitor for a few minutes, then power it back on.
Like other computer hardware, the monitor may not initially turn on correctly.
Move the mouse and press the "Enter" key on the computer keyboard.
If the computer is in sleep mode, the monitor is going to appear as if it does not have any display.
Hope this helps
