Make sure fan is working,clean the dust from it if necessary, make sure it is sitting and a hard surface where air can move to escape from the machine aswell as air getting in the machine

Computer keeps powering down wwhile I am working on it. just shuts down


Time to clear out those dust-bunnies clogging up your cooling system.
Open up your case, take it outside and blow it off and or vacuum taking care not to dislodge any connections.
Overheating causes failures typified by mystifying shut-downs.

Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

Hi,

I suggest try to check these things on your machine.

->Check if the machine is Overheating.
->Check which part of the machine is Overheating.
->See if the Fan of the machine is Running(Feel if the air vent of the machine)

Cause of Automatic Shutdown:
-Memory
-Hard Drive
-Fan is not working

Most likely those are the cause of the machine keeps on shutting down unexpectedly.

Computer shuts down on its own


Most likely when a computer shuts down on its own it is because the computer processor or power supply is either overheating or is under powered.
Feel with your hand around the computer case and back of the power supply (has circular fan usually/ on off switch/ and a plug goes into it)
If it is very hot you will have found your answer.
Did you just install or upgrade a processor? If so you may need to check to make sure that there is thermal compound (artic silver, etc) between the processor and heat sync. This can cause overheating and sudden shut downs. If not move on
Is your computer in a small enclosed area? Try moving it to an area with more area for ventallation and cooling.
Do you have adequate cooling/fans? are they working? if not check power cables and may need to replace the fans or install more. You can buy and install case fans pretty easily
DUST. Are the fans and imputs dirty? Keeping them clean will keep the computer running cooler and help lower temperature and avoid shut downs. If your fans/imputs are dirty remove dust by using a can of compressed air, a vacuum made specifically for pc/electronics. or you may wipe them down with rubbing alcohol and a dust free cloth.

The computer will just randomly do a windows shutdown and then restart. Cleaned, changed the power supply and still does it.


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 computer back on and figures out a way to foil the protection, the unit is probably doomed. Once a unit 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 unit 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. Check the CPU fan if it is spinning and also the CPU itself put thermal paste. So that the heat from CPU will absorbed by the heat sink.

It is one of 2 things....

1. It is overheating. Overheating will cause the computer to randomly shut down. You can usually decifer if it is overheating by trying to put the computer back on after it shuts down. For example , start it up...let it shut down...then try to put it back on again...if it doesn't come on at all, or if it shuts down even quicker then the previous time, you are most likely looking at an overheating issue. To remedy that you want to open up the case, clean out all of the dust with a compressed air can (be very careful not to tip the can, it will spray liquid), and verify that all of the system fans are running.

2. Could be any type of hardware failure - from the power supply to the hard drive. If you have completly ruled out the overheating issue, I would just take it to a shop to get diagnosed.

Toshiba Satellite M55-S325 turning itself off


Hi subji, try running the notebook without the battery connected & just the AC adapter. See if the notebook continues to shut down. It wouldn't hurt to raise the notebook off the table surface anout an inch but check the function of your notebook like I mantioned (without the battery first).
Post back your results.
