It could be almost anything. Obviously your power supply works and your motherboard should be ok. Other than that, it could be any of the rest of your hardware. Try running Memtest to make sure your RAM is still good. Reseat the RAM too just to rule that out. I have seen a bad DVD drive keep a computer from booting, try unplugging that and see if it makes a difference.

The graphics chip might have gone, but the only way to know is it boot it up and see if you get a boot screen or maybe as suggested by Kevin boot into a live CD. also try attaching an external display...this might help to work out if it's a fault with the laptop display or the graphics chip. I've had a graphics chip go on a mates laptop and I had to break the bad news that he basicly needed to get a new laptop because if the graphics chip does go in a laptop you've pretty much had it. I hope this has been some help :)

A few people have said the laptop is trying to boot off of the external hard drive. I have now got to a blue screen and mouse on screen but nothing is happening at the moment. The problem is I don't have a disc for this laptop...
