Laptop shuts down without any sign of BSOD, it just dies. Won't restart until it's been off and batt

Basically title. It's been happening a lot more frequently, and it's starting to tick me off.
Basically I can be sitting in a game, talking to someone on Skype. Suddenly, out of the blue, the computer just dies. No BSOD, no error message. The monitor just goes blank for a second and then it shuts down. If I try to restart it, it will go to the boot screen and then die again. To get it working again I basically have to unplug everything, pull out the battery, and let it be for a few minutes. Then it will work again.
This has happened TWICE today. Which is just horrible.
Now I have some suspicions. Overheating. It could very well be. As of typing this message, the temperatures are currently:
[LIST]
[*]CPU: ~65-80 Celsius
[*]Motherboard: ~60-75 Celsius
[*]Harddrive: ~50-65 Celsius
[/LIST]And from what I can gather, that's pretty high. And this is just from typing. When I play games I can read temperatures near the 90 to almost 100 Celsius on CPU and motherboard. My guess is that the computer does an emergency shutdown to prevent damage on the CPU (something I've read on another forum before I made this thread).
So I'll go out on a limb here and guess that it IS overheating. This is a laptop we're talking, a one year old laptop at that. What can I do to prevent these crashes from happening? I'm already using a cooling plate, and it's no good help at all. I suspect my fans might be dying because it makes a lot of noise.
Specs
[LIST]
[*]Windows 7 64 Bit Home Premium
[*]Intel Core i5 @ 2.27Ghz (Dual core)
[*]4GB RAM
[*]ATi Mobility Radeon 5650 HD
[/LIST]It's a laptop labeled "Packard Bell TJ75". According to [URL="http://www.notebookcheck.net/Review-Packard-Bell-Easynote-TJ75-Notebook.27217.0.html"]this review[/URL] of it:
[quote]Some notebooks that can be used for gaming have the reputation for being mobile fan heaters. When it comes to the Packard Bell TJ75, this is not the case. When submitting it to the stress-test, we only measured a maximum of 37 degrees Celsius on the working area (in the middle of the keyboard). The important hand resting area however stays at a comfortable level, below 28 to 32 degrees.[/quote]
I cry. Because that is most certainly not the case. The hand resting area gets very warm during games.

I fixed it by opening up the laptop, taking about 5 or so mm of dust off my heat sink, and applying thermal paste. HP did a shoddy job, which was part of the problem.

Interesting. Yeah, makes sense. I haven't opened this thing up once since I bought it almost a year ago, so there's a good chance it's filled to the brim with dust. I'll take a look inside it tomorrow. Should I unscrew the entire back or just the parts that actually have lids on top?
Look up the user manual online, it should tell you how to get to it.
The most common overheating problem on modern laptops is the heatsink fins on the end of the heatpipe become clogged with dust, and the blower can't push air through the fins anymore, leading to overheating.
To access the CPU cooling device and the CPU, there's usually a panel on the bottom of the laptop that can be unscrewed, no need to tear the laptop apart.

That was the issue with mine. However, to uncover the heat sink I had to take everything out.

Which is because HP decided to be a bunch of dicks when it comes to servicing.
On my old HP laptop I had to unscrew the entire bottom and keyboard of the laptop to get access to the cooler, while on my current Lenovo laptop all I have to do is unscrew two screws on the bottom and I have access to CPU, GPU and cooler.
Stay classy, HP.
