There are a couple of things that can go wrong with it. The most common thing on laptops is overheating.

You will know if your laptop is overheating if it happens one ore more of the following:
-The keyboard and the bottom of your laptop are very hot when the laptop is working.
-The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
-The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
-The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner

If it is not overheating, then it is a hardware failure. Could be the RAM memory, processor or the motherboard. You can test the RAM with this program: http://hcidesign.com/memtest/MemTest.zip

If RAM is ok, then only replacing hardware equipment could corner the problem.

Fix OVERHEATING Notebook


This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:
  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A135) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

My Toshiba P35-S611 shuts down without warning a short time (2 min-45 min) after it boots up. The battery isn't hot but the heat dissipation fins in the back are very hot.

Overheating and turning off


Laptop shuts down? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed. Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

Installed new larger hard drive now crashing after an hour use


When you say "shuts down" do you get a BSOD (Blue Screen of Death) or does it just shut down without an error message? It definitely sounds like overheating. Try using a laptop cooler, something like this: http://www.overclockersclub.com/reviews/antec_notebook_cooler.php (I'm not saying you should buy that model necessarily, there are many such coolers). They can make a huge difference.
