PC randomly shuts off and randomly boots up after (sometimes).

Q: PC randomly shuts off and randomly boots up after (sometimes).

Hi there,

I am here in bad need of help to figure out what is going on with my pc of late.
A quick run down of the problem. When the PC is on it will depending on how long its been on will randomy just shut off. When it shuts off, it "sometimes" reboots but most often it "tries" to reboot but fails and then stays off. After this failed try to reboot if I press the power button on the case and mobo, nothing.
Now if I turn OFF the PSU leave it for a few minutes and come back turn the PSU switch on and press the power button the system comes to life for a second or two then dies and will no respond to the power buttons until I turn off the PSU again.

I have gotten it up and running from this state by leaving it off and unplugged for a couple of hours. When I say the PC comes to life for a second or two, I mean the case fans. If I get it booted up the BIOS is reset to default for some reason. Also if it makes it to windows, the notification area icons also gets reset... very very odd.

I have a short video of the problem, sorry for the darkness, I finally decided to video it and it was 11pm.

My first thought... PSU dying or Mobo. I dont have extra's so I cant test them.
Forgot to mention, ive checked for heat problems but none of my temps are high, they are all normal and its a Antec 1200 with tons of air movement. I keep my PC clean but this problem I just cant solve.
Event Viewer shows nothing expect for unexpected shutdown. My event viewer is clean from any errors also. I do not get any BSOD and this is on a fresh Win7 install from late Jan. Its been doing this thing now for a couple of months. I am 99.9% positive it is not a software problem.


Preferred Solution: PC randomly shuts off and randomly boots up after (sometimes).

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Ok I am fixing someones dell dimension I believe it is a 2300 running xp and it boots up just fine with no problems. Then all of a sudden after about a minute it shuts down. Then if you boot it up again it boots fine, but shuts down a little quicker. The longer you leave it off the longer it will stay on, if you continually turn it on and of it shuts down faster. The difference is only like 20 seconds.

I tested the power supply with a psu tester and it passed.

I cleaned the memory stick and made sure there was no dust on it or in the slot.

And that is all I have tried

Any idea what it could be?

Thanks alot guys

Hello. First of all, thank you for reading my post. I recently discovered a Trojan on my computer and instead of going through the tedias process of getting rid of it, I decided to wipe my hard drive and load a 64 bit version of windows 7 ( an upgrade from the previous 32 bit version I had with the virus). The installation went smoothly and I began to download most of my drivers with no issues. I even downloaded World of Warcraft with no issues. I turned my computer off and got some sleep. I returned only to see that my computer would keep restarting during the start up process.

So, knowin a little about computers, I shut everything down. Checked and cleaned the inside of my PC. Re-set the memory and reset the battery to reload BIOS. I put everything back together, and it started up no problem. Success!!! NO! As I began surfing the internet, IE will randomly shut down and just keep doing it. As I scrambled for a solution to this very annoying problem, my computer would shut down, sending me to a blue screen which states a bunch of stuff that I don't understand. Being the hands on guy I am, I went back to search for a solution with the new information. I figured that maybe BIOS wasn't updated or that I didn't have all the needed drivers downloaded yet.

So I went to download some more updates and every time I go to download something I get a setup error or something that keeps the download from finishing! So, I threw my hands up and came here, hoping that som... Read more

It all started when i opened some foreign file and it mustve been a virus or something. That triggered my computer to make these weird whirring clicky noises. Then my computer shut down. That day, i tryied to turn it on, it worked. However, the monitor didnt display anything. The computer was running but something to do with the bios just wasn't working.
Later on, my father fixed it.
However. NOW, the computer randomly shuts off by itself.
I'd start the computer on, and usually, the computer would start to make these noises similar to that of a computer reading a disc.
after the noises, the computer shuts off, and restarts by itself.
Anyone have any ideas?

So this time the problem started out as a simple issue. Whenever I bump the desk or move the keyboard out with too much force, the computer shuts off. Everybody told me that it could have been a loose connection so I checked it all and replugged everything back in. The computer starting working fine for about 5 hours then it just shut off randomly while I was playing a game. This time, though, it shut off without me bumping into anything. SO, is this a power supply issue? I'm using a 550-watt supply while running a 7800 GT. This is the right power amount so that's not my concern. And now the problem has gotten worse to the point where I turn on the computer and nothing shows up again. Windows doesn't load and the screen is on too. You here the fans and everything but nothing will load. All my parts from my old issue were replaced EXCEPT the power supply and CD-drive. I don't think it could be another loose connection b/c now nothing even shows up. Please help!!!

I built a new pc with AMD fx8150 with ASUS M5A97R 2.0 .
I had never seen such a bios before with so many complications

(Compatibility Support Module /Secure Boot/Win UEFI MODE or Other OS/Legacy Mode/Both Modes/Load Keys/PK/KK/KEY Management... etc)

so loaded bios default and installed OS Win 7 Ultimate x64. (Bios showed 2 DVD drives in boot selection menu when i have only one).
I completed the installation and when rebooted the windows returned with error "disk read error occurred-press ctrl+Alt+del to restart) and this continues for 3-4 times and suddenly 5th attempt will boot my windows.
sometimes it will only boot after i enter the BIOS>Boot Menu>Boot Priority and select BOOT OVERRIDE option.

please help me out of this strange situation

(note: i was going through few article on web but they confused me more and more mentioning about MBR and GPT.. i am non technical person so its very hard to understand what they mean)

Hello There,

Machine Info: AmdK6 2400+, Phoenix BIOS, Radeon9800Pro Videocard, 1 GB RAM. 80GB harddrive. Virus Free.

My problem is as follows. When I start it up I sometimes gets the black screen and nothing more, and sometimes it starts perfectly. Today it has been almost a week since I managed to start it up. It started out with a black screen two weeks ago and has graduaaly moved down to complete darkness as of today.

What I have done so far, one step at a time: I replaced the CMOS battery with a fresh one to make sure the BIOS had enough power. I replaced the power supply with a new 450w to make sure the whole system had enough power. I replaced the the Radeon card with a GForce2 card to test if the video card was ok, which it was. I have disconnected my DVDplayer/writer. I have tried to disconnect my harddrives, one at a time, nothing happens. I also took the memory sticks and checked the connectors but nothing strange there.

I am pretty much going nuts over this machine. To say the least.

I deeply appreciate all assistance to solve this problem.

After I shut down my system - Start - Turn Off Computer - Turn Off, my computer has booted up "by it self" twice now. I turned it off last night before I went to bed and wake up and its at the log in screen. Before I went to church this morning, I turned it off and made sure it was off. Then, I come home, and its back at the log in screen. Nobody has touched it - nobody's been here. I have a computer ghost :x

i dont know if it really boots up randomly, but i notice that everytime i connect to the internet with my zone alarm off or set to medium, my PC automatically shuts down.. can't detect any viruses, adwares or something like that..

also if i have established a connection already, i can't go to some websites including this site! i can't even ping them.. i'm just using a dial up connection..

I can't address the possible connection between your internet activities and getting shut down, but when the computer turns itself off for no apparant reason, I automatically start look at the Power Supply.

My computer boots up at random times to a Red Block. It freezes on said screen to which I shut down the computer down and able to restart it fine. Once or twice did it repeat itself in a row. I have ran scan disk, sfc /scannow, AVG virus scan (daily) which is up to date (daily), and Spybot run and updated (daily).

My computer information, if it helps. This is from the Dxdiag if you couldn't tell.

Google kept giving me Red hat information and nothing else. So any help would be appreciated.

Hi, Try to update the BIOS of your computer.  NOTE: Sometimes updating the bios mess up with the log in password of your computer. Before anything else, kindly remove the password or unlock the computer by pressing Windows button+R then type netplwiz then click okay. Then under user uncheck the box then type the login password then confirm it. Dont touch the user name. After the update just do the same instruction then put a check mark in the box to activate the login password again. Go to https://hp.com/support. Enter your computer's product number to the search bar and press enter Click Software and Drivers then click Go   Click version then select the operating system of your computer.   It will then show you the list of drivers you need. Just hover to BIOS then download it manually and run the driver.  Hope it helps.

Hey guys im new and needed some help here. I recently encountered a problem with my pc like 5 days ago. My pc started shutting down by itself. It kept doing it.. sometimes it would get to the windows xp loading screen and keep shutting off... sometimes it would last from 5 minutes - 3 hours or so without restarting.. but it always does.

I just got my PS4 a few days ago and it wasn't until now that I was able to start playing with it. At first, while I was setting it up, it would shutdown while I was trying to find information about particular functions. I didn't think anything of it at the time. Now that I've finished setting it up, it will freeze and shutdown if I'm doing something as simple at looking through the menus on the main screen. I found information about how update 2 was causing problems and that update 2.01 fixed that. However, I have update 3.11.

So, before I return it and hope the second one doesn't have a problem, any solutions?

The main problem is the PC will power off instantly at random. The power supply is about 1 month old and was working flawlessly in a previous P4 system. It is a corsair TX650W and when the computer is booted up all the readings are good. The CPU is a -used- AMD Athlon 64x2 2.6 ghz 65w Socket am2 that has a stuck temp reading. It will run at around 23c on idle on core 0, core 1 is stuck at 93c and will not move on load or idle. It has a pretty good scythe cpu cooler with a nice thin coat of AC5. The cpu temp on core 0 will climb to about 35c on 100% load in prime 95 while core 1 will remain at 93. It wont get past 10 minutes in prime95 without crashing. It will simply power off all the way and has no beeps or errors when i reboot.

Some other specs on the PC would include,

Motherboard: A760G M2+
RAM: Mushkin 2GB DDR 2 800 MHZ 4-4-4-12
Video Card: ATI 4650 1GB Pci Express
CPU: AMD Athlon 64x2 2.6 ghz 65W with Scythe 6 pipe cooler
HDD: 320gb Sata, 80gb IDE
PSU: Corsair TX 650W single rail @52amps
OS: Windows XP 32 bit

The interior is nice and dust free and has plenty of air cooling. I'm leaning towards the cpu being the defect. It is the only item i don't have much history on and has a stuck sensor. If anyone has any suggestions on how I can troubleshoot this or what they think the issue is I would greatly appreciate it.

A:New PC, randomly shuts down

A simple thing to try and I am sure we are all guilty of is a loose connection, replug in every power connector with extra care. Try a different temperature monitoring program I use core temp, speed fan is another one. From what I can tell you have more then enough power(but im no expert).

The only thing I can think of is what you already posted, swap out your cpu and if the problem persists swap out your psu.

Or wait for a member with a higher tech level to answer.

Hi. I have a personal computer running in windows 7. I am unable to use for 1 month now because it randomly shuts down. If I leave it opened without using it, it won't shut down. But, if I use it like surfing the net or using photoshop, it will just shut down randomly.  I tried to use it on safe mode and what I did was just to uninstall programs but then it still shuts down.

Hey guys, well i'm sure you've heard this problems before.
My PC keeps shutting off randomly for no reason.
And before you say, its definetly not overheating,
I have a Thermaltake Xazer Wingo case, which has more fans than you can count. (Also i checked the CPU temp in the bios, and when it was running on high load, via a 3rd Party piece of software)
my AMD Althlon 64 939 3200+ normally averages out at about 45 degrees under load.
However now and then i can hear a strange wirring noise coming from one of the fans( it sorta sounds like the fan slowing down and speeding up again), i think its either the VGA or the PSU fan. Possibly the CPU, i'm not sure its hard 2 distinguish between all the fans lol.

and a faint buzz coming from the Power supply
(550 Watt Colourlite Piece of cheap crap)
So my bet is that its the PSU thats dieing.

Wow this is the longest the PC has gone without shutting down. As i'm writing this i have the side of my case open, and it doesn't seem 2 be shutting off.
the Graphics Card i have in is a 6600GT (AGP) which needs 1 molex power connector if that helps.
Or could this just all be a software fault? No message comes up, and the PC runs fine no lagging or skipping, but suddenly poof, PCs off.

Do you think i might be able to claim a warranty on my PSU?
Just throw your opinions at me please

A:PC randomly Shuts Down, think it might be my cpu...

it is probably your PSU. you can buy a chaep PSU tester for around 12.00.

Hi all,

For over 2 years my pc shuts down randomly. 3 months ago I took it to a pc repair shop and the techy analysed it and said it was not a hardware problem, but a software problem, he changed windows and added a new C drive. The pc still shuts down, but around 50% less than before I changed windows and added the new drive. Randomly as in it would shut down when videos are playing, when its all quite and in between. I have no idea what's bugging it. I do not suspect heat issues, but it could be the culprit. Thanks in advance.

A:Pc randomly shuts down

This seems to be a driver issue or Overheating as you have mentioned it yourself.

Try to download the latest driver from http://www.nvidia.com/Download/index.aspx?lang=en-us
or if it is due to overheating,try and keep your PC clean and make sure your PC is not in a hot surrounding like exposed to sun from a window that could also cause overheating.

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?

A:Randomly Shuts Off

Sounds like a PSU issue. Check and double check all internal power connections. If that doesnt' work, then the next step is to get a hold of a spare/second Power Supply and swap them out to test.

A:Is my PSU going bad? PC shuts down randomly

If I need to get another one, which one - I don't want to spend over 40-50 dollars, I know it is cheap range but with all this KVM stuff, it is getting expensive. Like I said, 5 year old, was the best you could buy at the time and the machine runs good but I wanna do a whole new system soon so this is just to keep it going.

HI All

IM wondering if anyone can solve this puzzle for me.

I built this pc and it was running really well until i changed the graphics card from a hd radeon 4550 512mb to a radeon 5500 1gb.Now it randomly shuts off. Now obviously the thing to do to solve the following problem would be to change them back BUT the problem persists.

I have changed the memory from ocz 2gb value stick 88mhz to 4gb hyper X 1066mhz to make sure it wasn't bad memory.

Ive added an exhaust fan that sits directly under the gpu fan and an 80mm system case fan that sits directly in the vent path of the Zalman cpu cooler that i have.

My specs are:

OS Version: Microsoft Windows 7 Ultimate , 64 bit
Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+, AMD64 Family 15 Model 67 Stepping 3
Processor Count: 2
RAM: 4095 Mb

A:PC Randomly shuts down


Read other 7 answers

My laptop, which runs on Windows 7 Ultimate, has begun shutting off for no apparent reason. It started a few days ago and was shutting off when I was on the internet sometimes. I also got a certificate error on my banking website, which I tried logging into from another computer and didn't get the error.

Thinking I might have an infection, I began trying to run different programs as follows:
1. Windows Security Essentials - Will run a Quick Scan, but shuts down computer about 1/4 of the way through Full Scan.
2. Malbytes - Shut down computer about the same place.
3. AdAware - Shuts down computer 1/4 - 1/2 way through.

I would greatly appreciate help finding this bugger & getting rid of it!

I'm having the same problem. Seems my system used to shut down (partially, leaving lights on) after about an hour. After having switched the power supply yesterday, I found it stayed up for almost 8 hours before shutting down. I was sure I had the problem solved. Now I've stayed up for about 6 hours in Safe Mode. I don't know how much longer that will last, but it's still better than the 45 minutes to an hour I was getting before. Yikes. There are a few other posts about this issue on this site.

A:PC randomly shuts down

Hi Dana. I would suggest that you go to our Virus and Malware Removal forum because if you can run in safe mode that means there is the potential that your system is infected (or it could be due to registry corruption or driver conflicts). It is absolutely essential that you read and follow the 2 stickies at the top of that forum posted by Julio and that you follow the instructions as given.

Also, systems shutting down after awhile can be an indication that you have a heat issue and high temps will shut down a system fast. Is there any dust built-up?

then I returned determined updated bios left PC idle in BIOS to see if it would shut down in BIOS randomly and the PC DID NOT SHUT OFF in BIOS so PSU is working atleast

So I decided to install Linux on a USB and run a os through USB so the PC seems to not shut off when using USB OS but the moment I try to COpy a file to or from HDD POOF.... this made me mad and i left the PC aside for a few more months...

Hey there, Little bit of a noob(well, I lied, I'm as green as they get) BUT:

As seeing from the title I have posted, I have a little(big) issue.

First, Here are my specs for my CPU:

Dell XPS 720

Intel Core Quad
Q6600 @2.40GHz
2.40 GHz, 2.00GB of RAM

I'm not too familiar with any other specs for my CPU, but if needed to find, I will do my best.

The issue is that it just shuts down randomly. I did A full scan, and I don't seem to have any issues with malware, viruses, etc. Before it shuts down, there is no message that warns me of it, no "Attention," or "script" error message, as well.

I had just bought this CPU last November. I still have my warranty, and I have called, but still no avail. They "need more info". but I'm not the greatest on detailed descriptions, sometimes.

Extra Notes:
- My power bar is pretty lame., Need a new power bar supply?
- I tend to keep my cpu on for hours at a time.
- I don't defrag as much as I should.
- I have a lot of the latest first person shooter games on my cpu.
- I'm not familiar with cooling system, perhaps I should buy one?
Anyways, any help would be appreciated.

Thanks a ton.


A:CPU Shuts Down Randomly

btw cpu is short for Central Processing Unit, not for computer.

I would recommend checking the ventilation to the system and check that all the vents on the case are free of dust.

Check to see if its not getting too hot.

Does it shutdown after being turned on after a long period of time?

Don't open the case just yet as this may void warranty? You might want to check this.

Hey, first post here, having problems with my PC. I'm fairly decent with computers, and I'm pretty sure I've got the problem figured out, but I don't have a lot of money so I want to fix it on the first try. When I boot the computer up, it shuts down during the Windows loading screen. Twice it did make it to the log on screen, but as soon as I clicked my username, it shut down. I thought maybe it was something to do with the outlet I was using or the cable I had, so I tried every outlet, multiple power strips, switched power cords, no go. However, when I removed keyboard, mouse, etc; it would last a little longer before shutting down. I took it up to my second floor, thinking perhaps it was still just the outlet (this house isn't wired very well, several outlets have issues) and plugged just the tower to the strip up there. No peripherals, monitor, nothing but the power cable. I watched it, and it lasted a much longer time (4 or 5 minutes) but then shut off. My guess is that my power supply is dying, but I thought I'd ask you guys just to verify this before I spend what little money I have on a new one, only to find out that wasn't it (college kid, poor, you know the deal). Was working just 5 hours ago, shut it down and when I came back this was what I got. I'm hoping you guys verify what I think, or perhaps suggest something non hardware related that won't cost me anything to fix.

K so I have a new pc. Built myself and had a few problems getting it to turn on. Turns out I had to short two means that aren't even the power connector ones. Anyway I got everything setup, Windows 7 blah blah. I move it to my room from kitchen, cause kitchen had better lighting for working conditions. I turn it on and bam, it shuts off after maybe 7-15 minutes. Now I'm thinking it could be cpu over heating. It is hotter in my room. I left the computer on bios and slowly watched cpu temp climb. At about 39C it shuts off. Is that an over heating temp? It sits at that for a while before it shuts off. I haven't updated drivers yet, could that be a problem?

Cpu: Intel i7 3770
Psu: kingwin 750w
Motherboard: asus p8z77 - v lx
Gpu: radeon hd 7970

I also took off the heat sink after getting frustrated and taking everything apart when it wouldn't start, did that mess with the thermal paste? It looks evenly applied. When it shuts off, it's just off, no warning.

Please help

So I had this a 2 days ago, and I fixed it by just randomly plugging in and unplugging my video card and my vga cable. My pc was fine for 2 days.

And today, a new problem came up. My pc kept shutting down randomly, even without doing anything. But the first 2 encounters were just me browsing the internet.

What might have caused this? It's not an overheat I know. Can anyone tell me what parts/factors might be causing this?

PC Specs (in case it helps)

Palit GeForce 9400GT 1GB 128Bit DDR2
AMD Athlon 64 X2 2.7GhZ
2x 2GB Strontium DDR2 RAM
BIOSTAR NF615 Micro AM2 Mboard
Hitachi 500GB HDD
PSU is 550W, I don't know what brand.

It is a 5 year old desktop.

Any help would be greatly appreciated, please help. Thanks!

So my computer did this twice now within like a week or two. The computer randomly shuts down but only partially. The computer monitor would shut off so would the keyboard but the mouse would stay on and so would the tower light but it sounds like its powering down. I would sit their the monitor wont come back on or anything and the computer sounds like its running in sleep mode or something buts it is not. I hold the button to turn it off but it wont shutdown all the way. In the end I have to turn it off by the back switch. I then went to turn it back on but like half the pc turns on (tower light but no montior or keyboard). My cpu tends to get a bit hot (80c) because of the bad stock fan but its only about a month old. Please help, Does anyone know what the problem could be?Should I get a new cpu fan?

A:Pc randomly shuts down

First, you say it randomly shuts down. Do you notice if it shuts down doing particular things more than others?

We need to know your hardware, particularly your processor but also your power supply's make and how much wattage it is designed for.

If it is a heat issue then heat will shut down a system fast.

Hello friends,

Today my computer started crashing. Whenever the crash occurred my computer sounded incredibly loud, ostensibly with fans blazing. Additionally, I noticed the crashing was occurring during gaming (but it hadn't ever before), so I put a temperature monitor on my second screen. I observed that it was crashing at only about 80-83 degrees, which had never led to a crash before. My card is a GTX 760 and should, from what I have read, be able to survive 83 degrees without my computer crashing. Later in the day, my computer started crashing randomly. Then, whenever I booted normally I would only get a black screen with a white cursor after logging in. Then I reinstalled graphics drivers and the computer worked fine for half an hour and started crashing again. An hour later and it will only boot to the black screen with a white cursor (although safe mode working is absolutely fine albeit running on my secondary screen for some reason). Some of the crashes have recorded as bsods by my computer and I have done what the sticky says with them. I believe the issue is my card going bad but I would love a more knowledgeable opinion from the wonderful people here. The log files are attached.

Thanks in advance!

A:New Computer Shuts Down Randomly

Hello and welcome to Techspot!

First two guesses are either
a) you don't have the heatsink seated properly and your system is overheating. Try reseating the HSF with some new thermal paste.
b) Your power supply is dying. Raidmax are well known for producing low quality PSUs that die out early.
