Shutting down without warning

The problem persists. It is not a overheating problem nor a motherboard/cpu. all that checks out. we exchanged power supply, but it still just shuts down. Was thinking about wiping the hd, repartition and reinstall, not sure if that would solve the prob. Definitely need info/input. Hubby to leave for deployment in a few days.

Shutting down this way is usually loose or ill fitted hd,sometimes mem or conflicting software.
take out hd refit making sure housed properly.start up pc and see how it goes.
check mem.take them /it out of housing check for dust.. refit.
some tech's suggest taking mem out and swapping them around ..this has no impact the mere fact thet you remove clean and refit is all thats required.

NEW HP Spectre 13T-3000, 13.3" Touch will not run with the battery and shuts down randomly


you can use the unit without the battery. Remove the battery, plug in the charger/power supply and turn on the unit and wait for the result. if the problem persist?..... maybe the fault is in CPU fan. check the fan...overheating the processor. Cleaning the heat sync and reapplying silicon compound on CPU's can cure the problem.

Why is my computer shutting down without warning?


If the computer powers off with no warning - just turns off instantly, this is usually caused by overheating. If it is a desktop PC, the most likely culprit is the CPU fan/heatsink. It may need to be cleared of dust and new thermal paste applied to the CPU. If you aren't comfortable doing this, take it to your nearest computer repair shop.

If you have a laptop, it will be harder to access the CPU. Take it to your computer repair shop and ask them to check the CPU and heatsink.

Cpu high temperature, cpu shutting down


The CPU is shutting down because it is overheating (ie thermal shutdown) and won't boot up again until it has cooled down. If this problem is not fixed, eventually the CPU will fail completely.
Check the CPU fan to see if it spins freely. Also check the power supply fan to see if it spins freely. If the CPU fan has failed, then replace the CPU fan. The CPU fan and heat-sink assembly may be clogged with dust, if so loosen the dust and vacuum to remove the dust.

My laptop shut down after powering out with no warning and will not restart.... Toshiba L550 screen stays black but when I hit the enter key it beeps........any suggestions


“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!
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 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.

Intermittently shuts off, acts as if the whole computer goes into standby. shuts down VGA on video card and then CD ROM LED comes on and stays on.


It seem your computer is having overheating problem, before you try anything, clean the motherboard,heatsink,cpu,ram,etc... and blow away all the dust, then check the video card on another PC so that you can make sure it isn't the problem.. If problem persists, do let me know... Good luck..

System was up an running then, Then shut down


It sounds to me like it overheated and something burnt out, but I could be wrong. The main pieces in a desktop computer are: power supply, motherboard, cpu, ram, and video card (which is on the motherboard for lower end systems.)
Each one will need to be properly tested to find out which part(s) is(/are) failing, and the failing part(s) will need to be replaced.

Dell Latitude D610 Shuts off with no warning...


the problem is not the battery; what has happened is the coolant paste that pulls the heat away from the cpu (main) chip to the fan has dried up. you must remove the fan/heat exchanger off the motherboard and, put new paste on the chips that the heat exchanger sits on
radio shack sells the paste

My computer keeps shutting itself down without warning. I have live one care which prevents virus to pass through the system but the computer will stay on for a little while then shut off then stays on for...


It is possible this is caused by overheating. Check the power supply fan first, probably in the back of your computer tower. Do you feel any airflow? If so, the next thing to check would be the CPU fan/heat sink. Many motherboards have a temperature gauge software nowadays, or you can download one for free online to see how hot your CPU is running.

2 Possible solutions:
  1. Replace Power Supply if there is no air flow.
  2. Put in a new Processor Heatsink/Fan

L7VMM2 shuts down


I think you have overheating problems
Check all fans are working and vanes are clean including power supply one
Check heat sink on CPU that the vanes etc are clean and clear of dust and fluff
Give case a vacuum out including all vent holes also the ones on inside case of power supply
see how you go this problem is usually the cause of persistent reboot
