PC Shuts Off At Random

Mar 23, 2008

My computer just powers off wothout warning sometimes then won't turn on again for several minutes. The computer hasn't been overheating or even under heavy load when it happens. Which piece of hardware is the cause of my trouble so that I can replace it? The motherboard is an ABIT IS7, the PSU is a Coolmax 450W, and the CPU is a 2.8GHz P4 Northwood. Or is the problem with something else?

My PC Shuts Down By Itself

Jun 26, 2009

my pc started to shutdown by itself about two days ago.. it's a self-built with Intel Core2Quad Q6600, 4 GB Kingston 800 MHz RAM, nVIDIA 8500 GT, 320 GB WD SATA HDD, and ASUS P5K MB

i don't know the reason, but the night before it happened i detached the fan to clean it then re-attached it again "appropiately" and turned the pc on and it worked, and i did a deep system scan using trail version of BitDefender Total Security 2009 "which ends tomorrow btw" and i slept, and when i woke up the next day it was done and i read the report and all was good!

i turned it off, and by noon when i started it again, the problem appeared, and it started shuttingdown by itself since then..

i am writing this post while i am on SafeMode, and it's working on safemode and didn't shutdown in half an hour now ...

Boots Up Shuts Down

Jun 14, 2008

My windows xp that I have had for about 2 years suddenly started to shut down and restart on its own. Out of the blue, over and over. Boots up shuts down, Boots up shuts down. I use it for my business payroll and bill paying. When I do get it to stay on for a couple minutes I have to restart my active desk top. I have tried defrag and cleaning it up. Checked all my plugs and tried everything I can think of.

Randomly Shuts Off

Feb 19, 2008

My computer has started shutting off randomly within 5 mins of startup. By shutting off, I mean it just turns off...no BSOD, no errors, just turns off...at random intervals that are usually within five mins. I updated my display drivers a few days ago, and they're currently at the highest version, but it's been a few days, and this just started this morning. It seems to be fine in safe mode (which I'm in now to post this)...which leads me to think it is, in fact, display drivers...but they're up to date, I have no solution there...now what?

Shuts Down Unexpectedly

Jun 7, 2008

I'm running Vista Home Premium on an HP dv9000 laptop. A couple of weeks ago, my laptop decided to shut down on its own. No error message, no blue screen... it just shut down. It does not restart. It will not start again for two or three minutes after it first shuts itself down. At first, I thought it was a problem with a game (The Sims 2), and maybe my graphics card (an nVidia GeForce 8800, IIRC). Then, it started doing it at other times, sometimes when I was just surfing the internet. I can give more information about my system upon request.

Never Shuts Down Properly

Aug 11, 2009

We recently brought a laptop with Vista Home and have had on going issues with it not shutting down. Everytime we hit shut down it goes to the logging off screen but never actually makes it. We have left it running over night and come down the next morning and its still "logging off"! We have tried the Ctrl Alt Del combination to see whats causing the issues but the task manager doesnt load up. This has been an ongoing issue for about 3 weeks and have probably only had the laptop for a month.

Forceably switching it off, which we have to, causes the safety mode prompt to come on at the next start up. If we do not run the safety mode we arent able to use the internet as it doesnt connect. So, running it in safety mode is the only way to get things back to normal. I should add that when I start up in safety mode it goes to a black screen eventually with "safety mode" written in each corner. Ive no idea how to move away from this so just hit the main off button but we can get back on the net when it reboots.

Having read a few issues with shutting down it doesnt appear that anyone has the ongoing issue we do and as mentioned Ctrl Alt Del does nothing. On the rare occasion we have got it to shut down properly it reverts the next time. We run McAfee anti virus and as a fairly new laptop there isnt much that we have downloaded since purchase. I also have a desktop and never experienced this ongoing issue!

Random Shutting Down

Apr 8, 2009

This happens to me every morning when I turn my computer on after having it off all night.

I turn on my computer. Windows loads then I get a message (as soon as windows is done loading all up) that "Windows will be shutting down in less than a minute."

So it shuts down, restarts, and when it gets back on my User Account Control is turned off. So I turn User Account Control back on and it's fine until the next morning. Sometimes, but not often it will do this after my computer has been Hibernating for a while.

Random Lockups

Apr 9, 2008

I have an HP dv9000 laptop running Vista premium SP1. Both before and after installation of the service pack I have been getting occasional complete lockups, with the mouse, and keyboard both inactive and the disk access light off. The only way out is the power button. The system is about six months old, has no malware on it, has the latest BIOS installed and passes memtest. I have turned off folder indexing, updated all drivers from the manufacturer and, except for this issue, the system runs well and fast.

The lockups might occur once every couple of weeks --- usually, but not always, when surfing. I have not been able to reproduce the problem and it does appear to be truly random. Does anyone have any ideas what I might try next. The only other thing that happens is that when press the slash key I get his character:? or this one in upper case:? My keyboard is set to English.

Vista Shuts Down Abruptly

May 15, 2010

Iīm looking for some opinions about this issue Iīm getting. Recently I got as a present a vista ultimate desktop which previously hadnīt given any troubles to itīs owner. So I brought the pc home and started using it without a problem, but after one day the computer starts shutting down on me. No error screens, nothing, it just shuts down. It doesnt restart or anything, all of the sudden it goes blank. I can turn it on again, it boots and I can use it for a while and again it shuts down. I have left it on all night and it didnt turn off, but it seems to happen when I am using it. Thereīs no pattern here, it might happen at any moment, without any logical trigger. I opened the tower to check the fans and they are both working well. I downloaded a soft called everest to monitor fan and cpu temps, and both the motherboard and processors remain usually between 50 and 60 degrees celsius and the fan remains around 2800 rpm.

I have no idea whats going on and canīt seem to find any conclusive solution on the net or asking friends. I am certain this didnīt happen before I brought the computer home, but I also did a system restore to a date previous to when I brought it to make sure it is not software related and the problem persist. The computer didnīt suffer any hit or impact on the way here. I am at loss, the pc works flawlessly and I am thrilled to use it, but as long as this problem persist I have to continue using my old crappy laptop.

Windows Shuts Down Unexpectedly

May 2, 2008

Windows shuts down unexpectedly. Is there a way to pinpoint the cause based on the logs and errors that Vista produces? I have read at least a half dozen reasons suggested for this type of occurrence in general and wonder if there is information being captured by the system that can help pinpoint the cause for my specific case.

Problem Reports and Solutons / View Problem History shows 11 instances of this, 7 today at approximately 1/2 hour intervals and one 5 days ago, one 6 days ago and two 7 days ago. It says: Windows / Shut Down Unexpectedly / (date & time) Solution Available. However whenever connected to Microsoft site it never comes back with any solution. Information from one of those messages:......

Computer Sometimes Unexpectedly Shuts Off?

Apr 9, 2008

There are two times when I have noticed it stopping for a reason. Other times I do not know why it shuts off. Once it stopped after I had a flash drive in the USB port. I did the proper procedure for "safely removing" it, but the computer still shut off when I took the drive out. Another time the computer more or less went to sleep. I was able to restart the computer without it rebooting. I wonder if there is some way to set the time for it to do this.

System Shuts Down When IDLE

Jul 21, 2008

From time to time my system (Vista64) shuts down - when IDLE - for no reason. WIndows restarts and says: Windows recovered for an unexpected shutdown... error report send. How to debug? Note that the system is idle; only background processes are running.

What I've done sofar:
- Ran extended memory test: no problem
- Disabled power saving settings (as I suspected a problem going into hibernate/sleep). No effect.
- Disabled all "user based processes" as Picasa, Google indexing, CPU-temp watcher etc..
- Removed all USB sticks (no readyboost anymore)

I leave the system idle and 10minutes to 2hours later; bang; shutdown Note also that the system never chrashed when I'm actually working. So, not a severe issue but I feel intellectually challenged to get the thing under control.

Computer Shuts Down At Start-Up

Mar 23, 2008

I have a new Acer Aspire computer running on Windows Vista. I've had it set up for a week now, running every day without any problems. Today, I switched on the computer and before Vista loaded, the computer shut down on its own. I tried again and this time got a screen asking if I want to run a start-up diagnostic. I chose that and the computer shut down again. I switched on again and this time Vista loaded and everything was ok. Apart from installing daily important Window Vista updates, I haven't changed anything on the system.

Virus Shuts Down Every 59 Seconds!

Jan 18, 2010

I got her a Compaq Presario V2000 (Windoz XP Professional). It has been serving her needs quite well. But now she calls and says it shuts down every 59 seconds so she hasn't time to run any of its programs like antivirus or IE to connect to web to run maybe LiveOne scan or others. She has asked me to mail her a CD that will be self-booting and contain a good antivirus (and I would say, something like Malwarebyte too) on it, that will run and clean up her computer so she can use it again.

(After that, i need to talk to her more about protective programs for the machine....) She is of the opinion that the infective agent may be "worm.win32.nightshade or something like that." Quoting her. This Could possible be a form of the netsky virus, I can't be sure. At any event, I tried to shop for a curative CD for her problemo. All the CD's I could find contained very old antivirus programs (with three years or older virus definitions ....and most do not even say they remove those viruses..they talk only about "scanning for viruses" whereas we need a scan and a REMOVAL, that is a real antivirus program that works.... with current uptodate viral defintions. And a good malware type additive. Can anyone recommend any such CD, or else any other means she may be able to restore functionality?

PC Shuts Down Due To Trojan Virus

May 10, 2010

I know is it seems to be shutting itself down when it has just started up due to it having a virus of some sort, a trojan was mentioned. Can someone recommend what the best course of action is in this particular case? I suggested that if the OS (Vista) is accessible then reformatting the HD may be the best thing to do. But will this get rid of the virus/trojan as well? I am aware that this will involve losing all data. I'm led to believe rather than have the original discs, PC's these days come with a seperate partition which holds the OS, which is used when reformatting is required? How do I reformat the HD from here?

IE Just Shuts Down When Opening A New Web Page

Feb 20, 2008

Before I start begging for the heavy assistance, is there an area in here for new Vista users, that addresses what I hope are common issues? Mine include:Will not begin downloads IE just shuts down when opening a new web page constently dropping cable signal (Comcast) There are others, but I'll be back for spicifics. vista home premium (how do I know if it's 32 or 64bit?) I replaced memory with 4 gig of something I migrated several programs from my old XP system with PCmover. That actually went pretty good.

Random Crashes In Just About Any Videogame

Jan 11, 2009

When playing just any game it crashes and I get an error messege saying "Directx has encounterd an unrecoveralbe error"

and

Display driver "nvlddmkm" has stopped working.

Then the computer flickers in and out and I am forced to restart the computer manualy.

Thins I've tried is that I formated my main "C" harddrive and setup all newest drivers etc.

That didn't fix this.

Another thing I thought of is that the card was overheating, well it has a custom Thermal Right cooler and a 120mm fan but I still tried and opened up the case.

That didn't have any effect.

This is a strange problem because I am able to run tests such as 3d mark -Vantage, 06, 05 and 03 without any crashes..

Random Shutdown After MB/CPU/RAM Upgrade On X64

It quite old though. 3 years probably, but it's not making any noise and it isn't running hot. It has a big 12cm fan which is running fine and apparently doing a good job.

After Vista reinstall my system randomly, completely shuts down (like when unplugged from power outlet) 2-5 minutes after booting up. Booting process is actually succesuful. All drivers running. I checked ;..........
