If it turns on, then automatically shuts down, then there must be soemthing wrong with your cooling system. Probably your cooling fan is not effective anymore. Try to press F2 as soon as you turn your pc on to check if in BIOS page it will still shut down. If yes, then itis a hardware issue, but if not, then it is a software issue. Virus could also cause this to happen, try to go to safe mode by pressing F8 when you turn the computer on. You might still have access to your files, so back them up before you do a complete system restore to remove the virus.

Sounds like it could be a RAM problem. If you have more than one RAM chip in your computer remove one and try the computer again. If it works then either the RAM chip that you removed has failed or the RAM slot it goes is has. Shut down the computer and take the working RAM chip and place in the empty slot to see if the computer boots up. This will tell you then if it's the chip or the slot. If the computer doesn't boot up, just to make sure it's the RAM slot, take the other piece of RAM and place in the other slot and try to boot up the computer.

My laptop shuts down suddenly


Is it overheating? Is the fan and vents clean and allowing sufficent air flow? Was it left unattended and shut down? If so change Power settings to High Performance, change Sleep to Never, Change Hibernate to never. I don't know your OS to give detailed info.

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.


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 A70/A75) 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.

Sounds like you have a hardware fan & vent, the CPU shuts down when it gets too hot.
Check the fan, it should spin freely, clean the dust off the fan and heatsink assembly. Replace the fan if necessary.
When you use the laptop, make sure none of the vents are covered.

Shut down suddenly


Do you get any error-beeps of any kind? Like the battery is going empty? Or does it just go off suddenly? If the first is the case, your power connector in the computer or perhaps the powersupply could be broken. It could sound like your battery doesn't get charged and your computer isn't getting power. Then it will shut down. See if the power/charge indicator is on when connected to the power grid.

If it blacks out suddenly it's probably a more severe problem, but you might try to reinstall the OS (I'm guessing windows), but only as a last resort.
