Computer shuts down by itself - Comments Page 4

My computer was shutting down and rebooting by itself for no reason, one time during reboot it windows identified the problem as being caused by an update, then it shutdown again, on reboot it said the error that time was caused by the antivirus, that being Norton 360, I had updated Norton just that morning, I believe the problem was caused by a dodgy update, anywho to fix the problem I uninstalled and reinstalled Norton and as of yet today the problem hasn't occurred.

my desktop acer Aspire shut down twice this morning after i was on MSN hotmail chat? it did an automatic shut down and auto start up with scan boot (check disk for consistentcy? win fat...???)

My computer shuts down at 5pm everyday. It started this about a few weeks ago. It can run all day and then at 5pm it shuts down. It is not hot I have a gauge that shows me the temp. I checked the power control and everything is set not to shut down. What could be the problem?

EDITOR'S NOTE: Do you get any messages prior to the shutdown? Does it just go "poof" or does it do a normal shutdown? It could be something in a power profile causing the computer to hibernate. Look in Control Panel for the Power Options (under Performance and Maint).

My computer seems to shut down on days when it's extremely hot in the house. When my com shut's down the green power light stays on and I have to hold it down for a few secs. to shut it down. Did I pick up a virus somewhere. Any tips or help would be greatly appreciated. Thanks

EDITOR'S NOTE: I've never heard of a virus that's heat activated. I would suspect an overheating condition that's made worse by the high room temperature. Maybe a good cleaning inside the computer case (especially the heat sinks) would help.

Hey does anyone know why my computer is shutting off all the time. And when i turn it back on after it shuts down it won't come on i have to wait like 30 min and turn it back on. sometimes it shuts right back off after i turn it on and it loads. I have no clue what to do can anyone help.

EDITOR'S NOTE: No clue? Even after reading the article? Which of the suggested remedies did you try?

Same problem here. But mine is quite different. It shut down like the fans and cpu turns off but when I take a look at the led on my cpu it is lit in yellow green.. The shut down happens in random. I do understand that I can consider that this is caused by over heating, but the thing is that this problem started when I clean the dust from the cpu fans to incerase air flow to the processor. Another problem is that after booting it up since I really need to power cycle the main pc, my documents and all newly installed programs before it shuts down was deleted. Most of the time if the files are saved from default windows folder like my docs, my music etc. It like it performs a system restore after the shut down. I do have Panda 2008 Antivirus. Any suggestions? Im running win xp pro, Intel P4 3.0HT, 1G ram (512 each inserted in a ddr2 533 dimm), 128 VGA.

i have a sony vaio laptop with windows xp i bought it in 2005 not sure the model , it has been shuting down randomly on its own . at first i noticed it was only happening when i watched news or youtube for more than 15 minutes at a time , might have just been a quinkydink . when i turn it back on it takes forever for windows to start up can u help tx

EDITOR'S NOTE: Sounds like an overheating problem, I'd have the internals checked out at a service center.

Thanks for the cleaning tip. Saved me from heat up of CPU.

I have a problem with my PC shutting down by itself.
I have a dual boot system with XP and 98.In XP it is fine but in 98 it shuts down at random intervals. May be after 20 minutes, sometimes an hour or longer.It seemed to me to start doing this after running cc cleaner.I have run this program before though without problems. Unfortunately I have to use
98 at the moment.There are no error messages it just shuts down.However I have noticed a few odd things like missing icons or missing color from icons in the START bar etc.

EDITOR'S NOTE: Why is it that you need to run Win98? Maybe there's a workaround...

help! my computer shuts off IMMEDIATLEY as it is taken off charge. I can never move or go wireless with it! it drives me crazy. Do u think something is wrong with the battery?

EDITOR'S NOTE: Laptop batteries are controlled by electronics and sensors inside the battery and in the computer that can fail. So yes, most likely your battery is toast.
