Machine Randomly turns on and off

Q: Machine Randomly turns on and off

I'm trying to help someone with their Pavilion 500-2014 desktop and have come up with some mysteries... Inital problem was that it would turn off then back on randomly. Eventually it appears to have crashed a boot file and the typical Recovery method brought you right back to the UEFI screen. So after making a clone of the drive to make sure I had all the user files I did a clean install from the Recovery disks. Initally the rebuild failed and message said to repeat the installation. Finally got the OS (8.1) from the drives installed. Inital check shows all of the fans running and the machine is (reasonably) clean. System diag checks all pass. But the machine is still turning on and off. First mystery is that the system checks show the one 8GB DIMM in Slot 4.... Is slot 4 the primary slot for the 500-214??? I can't fnd any documentation. Second mystery is when doing a disk check I see that 90% of the 2TB drive is not allocated. The install disks left a small partition at the begining of the drive unalocated. Small partition for OS, gap, small partition for the BUILDPART and then a huge unalocated section. What's up with this? And when I dig a little deeper I find here that the correct BIOS should be 80.22 from 3/4/16, but this machine shows 80.46 from back in 10/3/13. Is there a typo someplace or did HP (or MSI) go backwards with their BIOS numbering? So anyone have any thoughts? Primary questions are: 1) Known issues with Pavilion 500 machines randomly turning off and on?2) What is the primary memory slot? Should the one stick be in slot 4?3) Why the bizarre drive allocation from the official HP Recovery disks?4) What is the latest BIOS version for this machine? (I will be upgrading it to Win10 once I get it up and running.) Thx!

Hello!

I'm looking for some advice and guidance.
I am not a technical expert on computer hardware. I understand the basics and that's about the extent of it.

My current PC is a Dell desktop/tower; it runs Windows 7; it uses an Intel Core Duo processor. It is a few years old (I'd estimate 3 or 4 years old). I plug my PC into a Belkin surge protector/multi-outlet device, which plugs into the wall electrical outlet.

My problem is that recently the PC randomly has been instantly powering-down and then a few seconds later powering-up again and rebooting. This happens twice or 3 times a day, on average. I have no explanation for it. I do know that it's highly annoying and I'm concerned and want to do something to fix this problem before any permanent damage occurs to my PC.

Last week, I searched the internet briefly for advice, and the two possible causes that popped-up in search results were: A) overheating, or B) issues with the power cord. Given that, over the past week, in my spare time, I have totally rerouted all the cords and wires behind my computer desk, to ensure that no wires were tangling, pulling, or weighing-down on the power cord for my PC. I also totally dusted out the cabinet and backside of the PC tower, and gently vacuumed the "fan" area on the back of the PC, to ensure it was free of dust and lint. I removed some random objects from the PC cabinet (CD's, mice, keyboard, etc.) to ensure that there was plenty of "ai... Read more

OCZ MODX STREAM-PRO PSU (700W)
8gb Corsair Vengance at 9-9-24 and 1600Mhz

I was told this was most likely a problem with HDD or RAM.
So i have tried replacing my HDD with an old spare, but the pc would still turned off. So i am running HD Tune on my primary HDD to test for errors.
The health tab returns no errors though so i am assuming that this is all good.

I ran memtest 86+ overnight , but with both sticks installed, and it returned no errors (should i retry with one stick at a time?) .

The apparent next cause of such an issue would be the PSU, but after runnnig occt for 30-60 mins it gave voltages on all 3 rails well within 5%, the largest deviation was about 0.5% . Should i also check the bios volatges ?

My cpu reaches about 70 C at full load under OCCT's burn in tests, so i dont think that would be a problem.

It seems to occur more in some games than others, although it also has occurred while at idle.

Also sometimes the peripherals and screen freeze for up to 3 seconds and then become responsive again, they also make the usb insertion sound when they reconnect , so i am assuming that they are losing signal from the mobo.

This leads me to believe that the mobo is the problem, although i dont have a spare one to test with at the moment.

One last note, it can freeze/turn off up to 5 times a day, but then work fine for then next 3-4 days... It seems completely random

Please help. We have an AMD 64 3700+ pc running XP (SP2). I use F-Secure anti virus, Windows anti spyware beta, Spybot and Ad Aware but am concerned that I have collected a virus from somewhere. I recently purchased a game from Big Fish Games (Strike Ball 2) for my wife and pretty much every time she plays it, our machine just switches itself off. I mean it completely powers down with no warning, no "Windows is Shutting Down" screens or anything. I have recently downloaded IE 7, and the latest versions of Firefox and Thunderbird after reading about their security issues. Could it be related to this, is it the game or something else (I don't want it to be something else!).
Please help in terms a relative novice can understand!

When sitting idol for an evening, this 5 year old Gateway PC simply clicks off, just like we had a power outage. It's happened 3 times. Power outage isn't the problem however as a professional UPS is in use. On the reboot, the DOS commands pop up offering alternatives for rebooting since the shutdown was forced. My question is: Can this be an early sign of the mother board going out and if so, is there a test to perform? Other than the problem as stated, nothing else out of the ordinary has happened. Suggestions? I have attached a full description of my PC.

Hello everyone,

Its an ibuypower purchase off of New Egg a few months back. The last few days, after the computer has been on for a little while (sometimes as short as ten minutes) it turns off - no shutdown and then turns itself on a few seconds later. I've opened the side panel and made sure all the connections are seated. The fans are running and there is no dust build up (I do air can out dust every few weeks).

Any tips on what I can do would be appreciated.

Heat:
- only use the laptop on a hard surface - with nothing blocking any of the vents.
- use a laptop cooling pad if possible
- blow out all vents with canned air (DO NOT use a vacuum cleaner or an air compressor, they can damage the components).
- ensure that the fan comes on and is blowing air out of the vent (may not happen at startup, but should happen after using it for a while).

For monitoring heat of the system, use Speccy or HWMonitor:

Hi guys,

I need some of your finest technical assistance!

I've been having a problem with my PC for months now where it seems to randomly turn off when under load (I've not seen it power off whilst doing regular tasks like word or chrome use).

I figured it was the power supply (that I have now replaced and the problem continues) causing the issues as the PC seems to just shut off instantly without warning. There are no blue screens or error messages when I turn the PC back on.

After looking at the event viewer this is what it tells me (see jpeg)

This is absolutely ruining my gaming experiences and if somebody could help me I'd be very grateful.

I'm having a problem with my new build, it keeps turning itself off at random times without warning. There's no specific pattern that I have noticed. Sometimes it won't even stay on long enough for me to reach the bios, and other times it will go all the way into my windows vista and stay on for a while. The first time I boot it up it was on for a good 4 hours, then it shut off. Turned it back on and it stayed on for like 2 hours. Now I'm at a point where its turning off at random times.

WE are using very similar parts in our rigs but your pc cutting out could be a list of things. Anything from bios setup, drivers for numerous things and even bad wiring or memory setup. Without knowing what you have done to this machine it's very hard to tell and this kind of problem is a process of elimination. Tell us what you have installed and anything you altered in bios. If you overclocking it, then it's no wonder but odds are it's your bios or memory, possibly a driver. Set the bios to defeault or reset the Cmos on the board to reset it, install this Nvidia driver here
http://www.nvidia.com/Download/index.aspx?lang=en-us

Restart following Nvidia instructions and see how it runs. Beyond that you may want to adjust your memory and try setting it a lower frequency. Many think higher speed ram is best but it's actually not, will read higher on Vista only because of latency. I run 667mhz ram unlinked and set to 533mhz in bios and then matches the cpu internal freq of 266mhz (q6600). You have double that. If you overclocking the ram is what will get you 1st, and god only knows what your timings are. Try the bios reset and make sure oyu have the correct Nvidia driver and then see how it's going.

EDIT: I just realized something very important and more regarding your memory you are using.. you can't install 1066mhz ram on a 750i! You can get it up to 1066 overclocked but you can only use 800mhz ram!! Scratch the rest of my advice, you need 667... Read more

My PC randomly shuts down. This all started roughly two weeks ago, but it keeps getting worse and more frequent. When it shuts down I have to flip the switch in the back, wait a few seconds, then flip it again before restarting. The power button on the front does nothing.
(The PC is completely off when it shuts down. It's not running at all)
I pinpointed the problem down to 3 possibilities out of everything I found on google that could be causing this.

1. Drivers are not up to date (this is a very high possibility BUT I think something is wrong because the updates are endless. Every time I log on to my PC, I get a notification from AMD that there is a new update available. I spent about an hour the other day just updating and restarting my PC over and over. Whats up with that?)

2. Overheating seems to be a common issue especially since it is Summer. BUT I have turned my fans up manually to 100%, simply started Overwatch, and just sat there at the Main Menu. My PC turned off within 30 seconds. I would say that is the issue but I have had my PC turn off during a Youtube video or just browsing the internet..... Plus my PC can handle BF4 and Overwatch with ease so why would it be an issue now?

3. I might have a virus. Windows Defender has been known to not be the best ( I have experienced this first hand) so this could be a possibility but I dont know for sure obviously.

I joined this website for this issue because I really dont know exactly what I am doing.

I recently tried to install some new RAM into my computer and noticed a problem; basically it wouldn't work at all. So after doing a bit of research I found out that it wasn't the right type for my computer. So I removed it. ]

Everything seemed fine until about 2 days later when my computer turned off randomly, without me shutting it down. I thought it could be the computer overheating so I lifted of the shell and cooled it for a bit. Not the problem, even without the shell on it still turns off. I have changed my PSU cable and still not working.

I've always been running on A/C power but lately my computer loses power for no reason. It's not that it shuts down, but instead it just turns off like it suddenly lost power. I thought maybe my charger was dying so I bought one from HP but that hasn't changed anything. My battery hasn't worked in a really, really long time so I never put it in the laptop anymore. I tried the computer in the outlets in my bedroom and in the library and I got the same results. Sometimes the power shuts off as the computer is booting, other times it lets me get to the home screen and I can play on the computer on a while before it loses power. I always keep my laptop on top of a chill pad. Although I've noticed my fan doesn't turn on when I turn on my computer. Is it suppose to? Also, I think I might have heard a noise from my fan. How can I be sure it's the fan?

The laptop is definitely old enough for some service. It is possible that the cooling fan is worn out and/or dirty... if the fan is not running properly, the laptop will sense a over-heating condition and it will turn off. Have the laptop serviced and new batteries are cheap enough on EBay

I have an Acer Aspire 4730z laptop, and recently it has been turning off (as if someone unplugged the power cable from a desktop) after short periods of use. It turns off when doing no particular task, but it just does it after 10-40 minute periods of time. It doesn't seem to have this problem in Safe-mode.

Does anyone have any ideas about what could be wrong? My current belief is that some component of the computer is faulty and its causing an instant shutdown. Also, the laptop didn't always do this, but only started to after a couple months of use. I also don't think that it is overheating because I've tried my best at keeping the computer in a cool environment.

Any help would be appreciated, thanks!

A:My Laptop randomly turns off

A laptop shutting down is usually caused by overheating. Blow out all fans with a can of compressed air. Make sure there is ventilation to the bottom of the laptop. Use a laptop cooler. Also, remove the battery and run it on the power adapter only. If that works, then the battery may need to be replaced.

How can I find out which part it is? If it's the PSU or Motherboard etc. IF it's a faulty PSU what do I need to check when buying a new one to make sure it's compatible to my motherboard?

Win 7 Ultimate on Dell XPS8300

I have an SSD as my System Disk C:, but retained the original HDD (plugged to its original slot) as a secondary internal drive for Temp folders, backups, music files etc. It is still a bootable drive, although the boot sequence puts the SSD first. The HDD is a Seagate.

This arrangement worked OK until quite recently, until the HDD started turning itself off at random, but usually within a half-hour slot in the mid-afternoon, after the machine has been on since about 7 a.m. This happens perhaps every fifth day, and has forced me to move my pagefile back to C: SSD from the HDD.

So far, I have done these:-

- checked the HDD with the Dell Hardware testing utilities, with the Crucial Storage Executive (which also reports on the HDD) and several other things. None of these report any problems with the HDD.
- run the full Chkdsk (Fix/Scan for bad..)a couple of times, and Fix only several more. A few file problems corrected.
- ensured that Power Management Never turns off the HDD
- checked the SATA cable connection, which seems OK

As far as I can see, the only remaining options for me are to:-

- replace the SATA cable
and/or
- replace the drive (which seems unwarranted as no errors are reported on it)
or
- reformat the drive completely and see where that goes

Because the disk drops offline at a particular time, I'm wondering whether heat build-up may affect a connection in the cabling; although the ambient temperature in my o... Read more

Hey, folks!

My new computer (one month old) recently started turning itself off seemingly at random (while playing a game, surfing the web, etc.). At first I thought it might be a faulty PSU, video card or mobo, so I took my rig into the guys who built it for me and they replaced the video card. This didn't solve the problem. I took it back and this time, since they too were baffled, they kindly gutted my machine and replaced every part (or so they say) including the video card, mobo and PSU. In fact, they upgraded the mobo to a higher-end model as their way of saying sorry! Everything seems to be running a lot smoother and the shutdowns are happening a whole lot less often - only once since I brought it home from the most recent repair attempt. In my book, though, once is still one time too many.

I've done my fair share of research on the issue and advice on the matter seems to range from a bad video card, mobo or PSU to Windows XP being finnicky to a loose stick of RAM. Needless to say, I am stumped and so are the guys who built this machine for me. So, with that said, I turn it over to you - the real experts!

First you need to try the monitor on another computer. If it works on another computer then your problem is most likely the video card.

Hey I've been having this problem for quite awhile now, everynow and again seemingly random my computer will turn of completely then startup again. At first I thought it was a powersupply issue, but after getting a new one I ruled that out. Then I thought it was due to power surgers so I got a surge protector to rule that out. So now I have no idea. The shutdowns do not happen when the computer is under alot of stress. Sometimes I can leave my computer on for days and it will never happen. Any ideas?

Hi, I'll start with a brief description of my PC. It's a 2400XP with a 400W Q-tec PSU, running Win2K with SP4. I've got ZA free, AVG free, spywareblaster, spywareguard, adaware and spybot as well.

My PC was running fine until a wire stopped the fan from turning, and the CPU overheated a couple of times, and hence turned itself off after an audible alarm. I've sorted this out, and set the fan speed to max, but the PC now regularly turns off with no alarm. It even does it when I use a floppy boot disc and leave it at the A prompt!! Most of the time it turns off after about a minute, but occasionally it will run for a few hours.

Please can anyone suggest where I should look to sort out this problem, as it's driving me mad?

Many thanks in advance, Chris.

A:Computer turns off randomly

Sounds like a hardware problem. Could be the Power Supply or an issue with the Mother Board. Or you may have fried the CPU or a memory chip.

I would replace the Power Supply first and then if that doesn't fix it, test the Memory chips to see if they have any errors.

I've had this problem for a while now. On my laptop there is a light that indicates that the wifi is turned on. The light randomly turns off and my internet stops working. The only way I can turn it back on is to restart. I've tried going to Connect To on the Start menu and then to Wireless Network Connection. When the wifi light has turned off, the Wireless Network Connection window will not open for me to try to repair or reconnect. It seems like a problem with Windows, as the wireless connection and strength are fine and all other computers continue working.

Ok, this is the weirdest problem i have ever seen. i'm a computer technician myself and have no idea how to proceed here...

my mom's computer has been randomly shutting itself off for about a week now. i checked the power settings and it wasn't set to shut off at a certain time. so i suspected an overheating cpu or too much drain on the psu. then later that day it shut off and wouldn't boot up anyore. it would get about halfway through post, no beep codes, and then return to the page that asks if you want to boot into safe mode or normal mode. it was like on a loop. after opening up the case i found out that there was plenty of power but that the cpu fan [the one on the heatsink] was SO clogged with dust it would barley move. after i cleaned that out i disconnected one hard drive[the secondary drive] and cleaned it off because it was also caked with dust. i connected it back exactly the way it was and didn't change any jumpers or cable placing. i reconnected the power and tried to boot it. it booted just fine.
into windows 98!
i don't have 98 on this computer. it's a windows xp with sp2.

what on earth? please help.

A family member has reported that her computer eventually randomly shuts off, often in sleep mode. I've run the followings antivirus programs: Norton Securty (the antivirus installed on the CPU), Norton Power Eraser, AdwCleaner (this found HKCU/registry/conduit), JunkwareRemoval, and MBAM. Besides the "conduit" line AdwCleaner found, everything else comes out negative.
 
So either this is a crazy virus or something with the computer itself. I caught the CPU turning off randomly. When I turned it back on, the screen saying that the CPU did not turn off right and "window error recovery" showed up. I chose to start up normally and Windows reported the attached picture file (I just took a screenshot of the window). I've no idea what minidump and the oher file is, but I'm guessing minidump has to do with memory.

I don't know what the problem is with my computer, I attempted to fix it by just reformatting, however it did not fix a thing.

I would be things on my computer like surf the web or click around folders on desktop/mycomputer, my screen will randomly turn black for 1-2 seconds, then back on, sometimes it simultaneously does it and it gets extremely irritating.

After I reformatted, everything was fine, and nothing turned off. However I came back home from school today and it just continuously goes black for a few seconds then back on. I also attempted using Symantec AV to see if it was a virus, I have no infections.

Also, when I play games such as CS, it won't turn black at all, I don't know if this is some issue with hardware or whatever, can someone please help me resolve this?

Thanks in advance.

Twice today, my laptop has, without warning, shut off completely. The only way to bring it back up is to plug it in, despite the battery being at around 30% or 50%. I had updated my computer in between the two shutdowns. I am not sure if it has anything to do with Windows 8.1 or not. If I could get help on this, that would be great. Have a good day!

It might not be any software issue. Laptop and its parts stop working optimally after a random time (generally 3 years or till end of your warranty). Also there can be any loose ends/ loose contacts. That's a general case though.
 
You can also try cleaning with CCleaner for any errors (just in case).
 
Check the battery health once. Go through the link if you don't know how.

Hello! I have a Dell inspiron laptop with a windows 7 OS. A few weeks ago, I had set down my laptop on my bed and had fallen asleep, only to awaken and see that it had turned off. I thought nothing of it then, believing it simply overheated but it's happened a few times since then. Today, I had set my laptop down on a glass table and I fell asleep on the sofa there, only to wake up four hours later with the laptop off. Again, I believed it was a heating problem but turning it on and going to the pool, I would return one hour later to see that it was off once more! It's strange, because it doesn't turn off when I am at it and doing something on the laptop but if I turn away form it, there is a chance that I may find it off when I return. It cannot be that someone is turning it off as I live by myself. Every time I turn it on after finding it off, it takes me to the Windows Error Recovery black page at the beginning.

Could this be a heating problem or something else?

Thank you very much!

A:Computer turns off randomly

Hello,

More than likely it IS an over heating issue started or aggravated by leaving it on the bed. That tends to block tightly the air ports in or out that vent the CPU and GPU.

The startup screen you note occurs after a crash so its not going to sleep or hibernation. You should check the power settings anyway and turn off any power saving features while your testing and switch to high performance. This should make the issue occur faster as well. Watch a movie or play a game to heat things up faster.

If that doesn't identify the cause let us know. If it does crash look to cleaning the vents with a vacuum, open the bottom panels and check for lint or dirty heatsinks and fan. if your lucky the thermal past is still good no balled solder issues.
Good luck,
Zen

The title is pretty self-explanatory. Occasionally, my audio will randomly disable itself (as in, the volume doesn't change but the audio is muted). Additionally, whenever my audio turns off, any video or song (as in, youtube videos and songs from iTunes and Zune) slow down dramatically. So, I cannot "watch" text either, because the video is playing at around .25x speed. Whenever it does happen, it is normally after I unplug my headset, but it doesn't happen every time I unplug it. Finally, it is beginning to happen more randomly. I will be watching a video and as soon as I pause it, the audio disables. Any idea what's going on?

A:Audio Randomly Turns off

Yes. Software is causing it to bug out.

Best thing you can do is update the software and drivers to all that you use, to latest. Some software tends to control the whole Windows audio stack when you start it, like some Cyberlink software. It can mute or dictate Windows volume.

For good measure, also install latest bios.

Test the system without headset attached at all after, if necessary, to see if that is the main cause still.

Hi guys

I was wondeing if anyone could give me a explanation for why my computer randomly turns off after 30-2h of it being on? The computer will boot up fine, load all programs like normal - i can start a game or word doc and work with those for a bit but then the computer randomly turns itself off! It wont turn back on straight away unless i turn it off/on at the back and unplug-plug it back in.

Now, I've concluded from tests that it is not the PSU (PSU tester) or a temperature problem (I've monitored my CPU - doesnt go over 50C = but not tested the MOBO temp - case temp is about 40-45C).

My specs are: ASUS P4-800SE, P4 2.8GHz, 1 GB DDR RAM, 320GB HDD, 500W Coolermaster PSU, 512MB Radeon 1650PRO AGP, Soundblaster 5.1.

I was wondering it could be bad RAM or MOBO - how could I test each component exclusively? Does it matter that the RAM (2*512MB) are in slots 1 and 3 (of 4))?

BTW I installed GOW around the time this problem started but did a system restore...

Any help would be much appreciated and merry xmas to all

Asus boards are usually pretty reliable but a visual inspection to check for damaged capacitors might reveal something - I have had the same symptoms before and it was either the main board or the capacitors in the PSU (Tested OK as well!) that caused the problem. Try another PSU if no fat caps on the motherboard - do NOT under any circumstances muck about with the caps in the PSU - there's almost enough volts in them to kill! No kidding....
