So you GPU has failed. This is a very well know problem with the Gforce Nvidia chips. It is a design flaw from nvidia, the chips are susceptible to failure due to thermal cycling. You can pull out your motherboard and reflow the chip and get it working again, but it will happen again down the road.

I would recommend replacing the laptop and writing some hate mail to nVidia.

It's dead. Probably the video system, but it could also be the CPU or MB. In any case, your best bet is to get a new laptop.

Have you, or is it possible someone else who had access to this computer...
- dropped it, or dropped anything on it, or otherwise exposed it to a physical jolt ?
- spilled liquid on it, or sprayed it with liquid, or exposed it to liquid such as rain ?

Since the video last worked properly all the time, has there been a power failure event that happened while the AC adapter was plugged in ?

Those things are the most frequent reasons something inside the laptop has been damaged.
.......

If you're SURE none of those things apply (you can NEVER be 100% sure of every one of those things), your initial problem was probably ONLY with the built in display.
Software problems almost NEVER cause white or colored lines on the built in display - that's usually caused by hardware problem with the built in display.

Try connecting an external monitor to the laptop.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:
http://www.computing.net/answers/ha...

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 (e.g. press both Fn and Fx ; x is a number).
................

If the video works fine on an external monitor, then there's probably nothing else wrong with your laptop's hardware other than the problem with the built in display
......

Software problems on the hard drive CANNOT cause video problems on a laptop BEFORE software loads from the hard drive while booting !
You should have normal video while booting the computer even when there is no hard drive installed !

You NEVER try to use Recovery disks or a built in Recovery feature when you're not sure whether the hardware on your computer is working properly !
You may have trashed the the original software installation that there may have been nothing wrong with !
.....

Computers that had a (XP) MCE 200x installation on them cannot have the MCE 200x installation installed from one CD. The official Microsoft OEM MCE 200x versions are only sold as TWO CD sets (I have one for MCE 2005). There is no Retail version of them.
HP may have a custom made DVD in the Recovery disk set that has essentially the same contents as the two MCE CDs,

,or, more likely, the HP Recovery disk set is a multi-disk archive that must be installed one disk after the other - you can't install just Windows MCE 200x; there is no disk in the set that you can use to repair Windows

If your model is not more than about 5 years old, you may be able to buy a Recovery disk set for your specific model from the Toshiba web site.

If they no longer have that, there are a small number of web sites where you can buy Recovery or Restore disk sets for your specific brand name model.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere.

Try here:
http://www.digitalmedia-labs.com/
http://www.restoredisks.com/
http://www.myrecoverycds.com/

If they don't list your exact specific model, if you contact them, they MAY be able to provide you with them - e.g. the same disks may be used for several or many models made by the brand at about the same time.
.....

If you have NOT completely trashed the the original software installation that there may have been nothing wrong with, if you boot the computer from a disk that has an operating system on it that can read all the files on the drive, e.g. a Linux boot disk, or the Ultimate Boot CD, you can use that to copy the personal data that is still there that you have added that you do not want to lose to elsewhere, BEFORE you use the Recovery disk set.

In that case, your laptop's hardware is otherwise damaged.
In most cases, except for high end laptops that cost a lot more money, the video adapter is built into the mboard and cannot be removed. In that case you can't fix problems caused by a damaged video adapter that's built into the mboard unless you replace the mboard.

You could try buying a USB external video adapter box
e.g.
http://www.tigerdirect.ca/applicati...

and using that with an external monitor, but your mboard may be otherwise damaged, or even if it isn't otherwise damaged that may not work because the built in display adapter can't be disabled by any setting in the computer's bios Setup in any case.

If you have NOT completely trashed the the original software installation that there may have been nothing wrong with, if you remove the hard drive and connect it to another working computer, and DO NOT boot the other computer from your drive, that has an operating system on it that can read all the files on the drive, you can use that other computer to copy the personal data that is still there that you have added that you do not want to lose to elsewhere.
E.g.
If your hard drive is SATA, that's easy. The SATA data socket and the SATA power socket of laptop (2.5") drives are identical to those on desktop (3.5") SATA drives - - you can connect the drive internally to any desktop computer that has a spare SATA data header and a spare SATA power connector..
