My NP9890 is giving me trouble. I was playing Scarface, and the computer shut down while playing. I turned it on, it would turn on for a few moments then shut down. I let it stand for a while, thinking that it could have overheated, turned it on again but still, wont stay up. Now it even shuts down before Windows loads. I've noticed that when turning the machine on, the Num Lock, Caps Lock and Scroll Lock lights start flashing simultaneously, and then the laptop shuts down.
I checked if the fans were operating, and they all seem fine. Perhaps my motherboard is fried? Or my video card? Or the vid card memory or internal memory?
If it is an overheating problem try turning the laptop off, turning it over and placing a vacum on the fan grill on the bottom. Many laptops get a dirt buildup internally and this will sometimes suck out the dirt.

When you shut off your PC do you:
1) Give it enough time (could take from 1 minute to 10 minutes) to shut down completely (easy sign is if the fun continues to run or lights are on)?
2) Clicked Hibernate or Sleep OR closed your laptop screen before it completely finished shutting down (this could put the PC to sleep and it would remain on, so the lights would remain on, until you woke it by moving a mouse, flipping the screen back and forth for a bit or pressing the start button (not holding))?
3) Have it plugged in (depending on the model, a light might stay on if it is charging even if it is not on(probably not this one since you said it turns off after a Hard shutdown (don't do this since this damages your computer and will make it break down after continued use)))
Tell them to give you a NEW computer. You got a lemon. They WILL give you a new one if you've had this much trouble with it. I'm serious, they do it all the time on lemons. Be assertive! They will cave.
Maybe your operating system is corrupted you need to reinstall it again. ======================================== 1. Your battery might also be the problem - it might be discharged 2. Install a reliable VIRUS scanner and scan your computer to check for VIRUSES
It could be overheating, and shutting itself down, to avoid heat-related damage.
Turn the computer off.
Disconnect the AC adapter.
Remove the battery.
Purchase a can of compressed air, and give your computer a "blow-job" -- shooting compressed air everywhere "inside" your laptop, to remove dust.
The dust is acting as an insulator, preventing your computer's fans from cooling itself.
Or, take your laptop to a qualified computer technician, for more trouble-shooting.
the problem is not your hard drive, if you are using vista then there are compatbility issues with certain programmes, if yoou are using XP all you need to do is download the latest codecs, this also goes for vista, try not to use XP programmes with vista because you will run into problems
