If you are hearing a beep after you power it on, that indicates the laptop is successful in a power on self test (POST). In this case, where you are hearing a beep, but not getting any video - you could have (a) failing LCD (b) failing motherboard.
In the event that you do not hear any beeps, try removing the power adapter, then the battery, and press the power button to remove any existing power. Plug it back in and try powering it on. If that doesn't work, try reseating the memory.
When you say the drive acts like it is running and stops, do you mean the hard drive or is the system itself sound like it completely shuts off (no fans, no lights, etc).

So do you hear beeps, maybe even a windows logon sound? Typically with bad inverters, the system itself functions (windows boots, fans running, lights, etc.) If you get all the positive signs there, but still a black screen, then yes it could be the inverter or possibly the backlight.
With a bad inverter, sometimes you can use a flashlight to shine directly into the screen and to see if you are getting a display. Inverters are usually cheaper to replace, but if that doesn't work you might need a replacement LCD.

will it boot with external monitor plugged in?
If you have a bad backlight inverter, it should boot, but you could only see what is on the screen by shining a very bright flashlight at it.

To turn on the computer, press the power button. When the computer is turned on, the power light is turned on.
If the computer and the power light are not turned on when you press the power button, adequate power may not be available to the computer.
The suggestions below may help you determine the reason the computer will not start up:
If the computer is plugged into an AC outlet, verify that the AC outlet is providing adequate power by plugging another electrical device into the outlet.
If the computer is running on battery power or is plugged into an external power source other than an AC outlet, plug the computer into an AC outlet using the AC adapter. Make sure the power cord and AC adapter connections are secure.
If the computer is running on battery power:
Remove the primary battery pack and travel battery pack (if applicable) and plug the computer into an AC outlet using the AC adapter. If the computer starts up, one of the battery packs may need to be replaced.
If the battery light on the front of the computer is blinking, the battery pack has reached a lowbattery condition, which may not allow the computer to start up. Plug the computer into an AC outlet using the AC adapter to start the computer and allow the battery to charge.
Check the movement of the Lid Actuator switch
The Lid Actuator switch is a small button or switch located above the keyboard near the hinge for the LCD. Pressing this switch when the computer is on may turn the notebook display off, or it may cause the notebook to enter a different power state.
Press the switch 2-3 times while observing the display. If the display does not return to normal brightness when the switch is released, the switch may be sticking and need to be repaired. If the display turns off when the switch is pressed, the power management function may be set to hibernate or turn off when the lid is closed.
It could be as simple as removing and reconnecting the connectors to the Video and the Display unit.
Mind you this is after you have checked with another Monitor to see if it isn't the Video Card.
