Since it still gave you problems after connecting it to an external display i would say it has a failing GPU. You could try retightening the screws that hold the GPU/CPU heatsinks in place and make them relatively tight and see if that works. If you can't get it repaired and that didn't work, you could attempt to "rebond" the GPU's solder joint. If you want to do that you can do so by one of two ways. You can let the computer severely over heat by running it with disconnecting the fans (Which i wouldn't recommend) or you could remove the logic board and use a heat gun to gradually heat the area around the GPU to the point that it melts the solder joint underneath it then let it cool down. It's very important to gradually let it heat up because if you do it too rapidly, you risk shattering the die of the GPU (which i did by accident to a RROD xbox 360)

Good Luck,

Chris

It might be a failing battery/power source. If the power spikes/lowers, you might see a momentary drop in brightness. Does it happen frequentlly?

you could sell the logic board, i have bought a few as-is parts, but it never works out for me, so I don't do that any more. You could sell it for 45-70 dollars.

the computer would probably be more
