|Your symptoms are probably caused by hardware problem, not a software problem.|
"But if its happening before windows boots (i.e. the Splash scren or BIOS) then its more than likely a hardware problem."
If you get the white bars at any time while booting BEFORE Windows loads (they may appear intermittently), then that can only be a hardware problem.
Have you, or is it possible anyone else has...
- dropped this laptop ?
- spilled liquid on it ?
Usually there's nothing wrong with the video adapter and the display will look fine on an external monitor.
Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.
Some laptops will display on an external monitor without you having to do anything.
If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
If the display on an external monitor is fine.....
If your problem is caused by there being one or more broken wires in the cable between the video adapter and the built in display, replacing that wiring will probably fix your problem.
If it's caused by anything else, you will probably have to replace the built in display assembly, or just make do with an external display.
If the display on an external monitor has the same symptoms,
then the video adapter is damaged. In most cases the video adapter on a laptop is built into the mboard and IS NOT ON A CARD that can be removed and replaced - usually you must replace the mboard, or in your case since you do have video on the built in display, if you don't mind using an external monitor, you could buy a USB video adapter and connect an external monitor to that.
Laptop video adapters, TV tuners
