PC randomly turns off then quickly turns itself back on

Q: PC randomly turns off then quickly turns itself back on

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 "airflow" around the PC tower (presumably to ensure no overheating). I rerouted several electronics that previously shared the Belkin multi-outlet device to another electrical outlet in the room.

I'm not sure if any of these actions was helpful or not, but I know that my PC is still having the same original power-off/power-on issue; no change.

I also updated and ran the "Malwarebytes" anti-malware software, and the full scan showed no infections/problems identified.

I am at a loss at this point, and would appreciate any help or advice. I've owned several PC's over the past decade or so, and I've never encountered this problem with any of them.

Preferred Solution: PC randomly turns off then quickly turns itself back on

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.)

After getting a couple blue screens I am having the following issue:

When I turn my computer on, the fans and drives all start up. After approx. 2 seconds the computer shuts itself off. After another 2 seconds the computer turns itself back on again. This time it stays on but i have no monitor output. I don't hear a beep which tells me it is probably not posting.

I have read a few other threads that have a similar issue but not the same. I am thinking it is either the mobo, GPU, or PSU.

I would like any guidance and assistance that you guys can give me on this specifically what i should look at first and how to diagnose. Thanks. system specs below:

ASUS P5Q Pro ATX Intel Motherboard
Intel Core 2 Duo E8500 3.16GHz LGA 775 65W Dual-Core Processor
EVGA GeForce GTX 260 Core 216 896-P3-1265-AR Video Card
Antec EA650 650W Power Supply
OCZ 2GB (2 x 1GB) 240-Pin DDR2 1066 (PC2 8500) Dual Channel Kit Memory
 

A:Computer turns on, turns off then turns back on but has no video output

Motherboard Short

I have helped somebody who had a similar issue and it was the motherboard being shorted out by the case. We took the motherboard out of the case and it booted up just fine. Something you might want to try before purchasing new components.

I HAVE READ OTHER SIMILAR THREADS ------ My PC actually has the fans / lights AND can't even get anywhere on the BIOS.

4gb ram
7950 GT
3.44 GHz Intel Pentium D
250gb HD
1 CD ROM
Foxconn P35A (mobo)
My mom took my PC away from me, I got it back and it is retarded now.
I start the PC, the fans come on, lights are all good, then about 2 -10 seconds it shuts off and then comes back on by itself.

When I turn the power on, the monitor does not show anything at all.

I have tried many of different things:

Different PSU ( problem is not the PSU )

D/C the CD ROM / HD ( so it can't be one of those as a failure )

1 stick of RAM ( my memory is fine )

Checked ALL of my cables, they are connected properly ( checked many of times, unconnected, then reconnected alot )

Replaced the grease between heat sink / CPU ( can't be my CPU or overheating problem )

Heat sink / Fan is properly mounted ( not loose at all and is flat )

All of the aluminum capacitors on the mother board are perfectly fine ( not leaking / and are on proper )

Reset the mother board a few times....

well thats MOST of the stuff I have done, there is probably more but I can't think of what else I have tried at the moment.
And BTW, can't access BIOS so don't ask if I can get into it.

Any help would be appreciated.

Do you mean you have tried resetting the bios jumper, on the Motherboard?
If not do that.

Also, have you tried disconnecting all HDD; Floppy; CD data cables (from the motherboard end (actually I'd do case fan too and front USB connection to motherboard)
If this works, you will need to put one back in at a time, until you find the problem

Usually this fault is related to faulty Ram or CPU

Hey guys I need help, during startup Windows Firewall turns off upon system startup and then turns back on a few minutes later, then network connections open up to finish up my bootup process. I have SP3, and this little problem is causing my computer to startup slowly significantly. I have tried scanning for viruses and spyware and have found none, so I really don't know what's causing this to happen.

A:Firewall turns off and upon startup and then turns back on

That's normal, in my experience.

Not just with Windows firewall but any other firewall I've played with...the network connection is the last line of system defense when the system boots.

The firewall won't allow contact with the Internet...until the system is totally setup and out of danger. The firewall activates (along with the other startup items), then the network connection is made.

when I turn my computer on, all the lights, the fans together with the MoBo lights turns on for 1 second, then it turns off for 3-4 seconds then turns on again until the OS loads..

when I restart my computer, this doesn't happen anymore.. It only occur when I completely turn the computer and UPS off..

I bought this system a month ago. I have to option to bring this to the shop where I bought it but I want to know what the possible issues are.. Most of computer shops here in our country replaces some parts w/o the owner's knowledge.. >.<

Please help.. Thanks =)

Seriously, I'd take this back to the shop and have them fix this at their expense. I would also take note of the parts you have now and compare them when it is returned.

Over the past week or so, I would get a windows notification that Avira Antivir has been deactivated. When I right click the Avira icon, I'm unable to turn it back on, but it does automatically about a minute later. This usually happens no more than once a day, and I'm wonder if some kind of virus or malware might be doing this.

Sorry about wall of text but its a pretty deep problemThis problem started about 2 weeks after I built my PC. One day, it just went poof and turned itself off. 3 seconds later, it automatically turns itself back on. I went into my windows and turned off the setting that means it automatically restarts after power loss, but it will still turn on on its own. I managed to fix this issue for about a month by opening it up, just fiddling about (things like pushing cables like CPU power and mobo power) and then I unplugged it from my surge protector and into my wall socket. It was absolutely fine for a month, I could play the most intensive games, temps are not a problem and nothing would happen. However, a month passed and then one day it turned off and turned itself on again. I am stumped.My educated guess would be that it's the PSU acting up but I am not sure why I fixed it for a month. I have noticed that every time I open up the computer and fiddle inside, I seem to hold off the shutdowns for a week or a few days. I have run memtest for about 2 passes with no errors, and I have not yet seen it shutdown when not in windows. It hasn't shut down in safe mode or in the bios (however I havent tested it for very long)My motherboard was already replaced before the build as it was DOA, and I have run stress tests on the GPU and CPU. (nothing happened)Any help is greatly appreciated, my main question is why was I able to stop the shutdowns for a month, and why is it that... Read more

A:Computer randomly shuts down and turns itself back on automatically

Hi,
 
Based on your information, you may have an issue with your reset button. As you built the PC, you're aware of where that is connected to your motherboard. Please disconnect it completely and see if that makes a difference.
 
I'm not sure by your description if when you "shut down" the PC yourself, if the PC stays off. Could you verify that. I'm guessing that what you're describing is the PC is not shutting off, but rather doing a restart or reset.
 
You haven't indicated if the Windows is giving you any BSOD or other message, or if it just goes black, and restarts. Please provide that as well.
 
Let me know,
 
Kurt

Ok so I'm having a problem with building my computer. I used to have a working gaming pc but i decided to upgrade so i upgraded my case my motherboard and my PSU. After i re-built everything and was planning on turning it on, all the fans started spinning and the Led's turned on but only for about 3 seconds. it then turned off. What i figured out is that whenever my CPU cable is plugged in this happens but when it is unplugged it doesn't shut off but also no Bios shows up. The HSF always spins very slowly and slowly stops working. My Motherboard doesn't have onboard graphics so i need a GPU. Pleeeeeaaaase help me!! i really want it to work and sorry for the nooby question.

PSU: Corsair RM 850

It plays that little two tone sound each time a device is added or removed...it is so annoying. I cannot use the drive as it does not stay "added" long enough. I am stumped...I have never heard anything like it. Have you?

Did the unit ship with drivers? ?
It also might be a cable issue. Inspect that cable or try a new one and or another USB port. If you have it on the front of the case try it on a rear USB port. I've seen machines where the front ports carried less power than the rear ones.

Hi everyone, a little while back the power pin of my Acer Aspire 5050 laptop came loose so it couldn't get power. I let it sit a while and just got around to ordering a replacement part. Now the laptop gets power but it turns off quickly. I've noticed that it turns off faster after consecutive attempts. (First time maybe 5 to 8 seconds then it just turns off a couple seconds after you try to start it.) The fan starting going hard before going off. I would have liked to experiment a little more and do more trials but I was afraid I might damage something. I have tried this with both the cable and the battery together and each separately. It doesn't make a difference. Thank for reading, any help you can give will be greatly appreciated.

Hello everybody!
I have a Dell Inspiron 3847 with an i5 4440, 8 gb of ram, and 1 tb of hard drive. I purchased an evga 500 watt PSU and successfully installed it. My pc worked normally and everything was fine. I then purchased an evga 1060 sc and attempted at installing it into my pc. After installing it I started up my pc and it turned on. The fan for the gpu didn?t spin so I turned off my computer, opened the case, unplugged the 6 pin then plugged it back in. I turned on my pc again but it made an odd sound before the power button flashing orange then completely shutting off. Now every time I turn it on the light turns orange and the fans spin for a split second then they stop. Any assistance will be much appreciated...

When all cords and such are plugged in, I press the power button. The desktop turns on for about 1-2 seconds and then restarts. The bios doesn't flash, the os doesn't boot. As far as I can tell the desktop restarts indefinitely. Any ideas what's going on here?

I found someone with a similar problem here

Desktop #2 Problem:
I bought some 3M Dust Remover a few days ago. I disconnected power, along with everything else, from a desktop of mine. Pulled the cover off and started blowing the dust out of the case. I put everything back together, plugged it in, and the desktop doesn't work. It boots to a blank screen with the the power and hard drive led's stuck on, on the front of the desktop. The led on the back of the power supply turns on, I can hear the hard drive spin up, it detects the cd/dvd drives, floppy drive and then just hangs with the led's stuck on. Anyone have an idea what might be going on here?
--Desktop Type: Compaq Presario S4200NX

Thanks for the help, I'm hoping to get atleast one of these back online w/o buying a whole new desktop.

A:HELP! Desktop turns on and restarts repeatedly, other turns on to black screen

Hi&#8230;.

Desktop 1:

Do you see anything on your screen at all while this is happening?

Have you tried to press the setup key to see if the BIOS will come up and make changes?

Do you have any USB devices (other than keyboard or mouse) hooked up? If so, try disconnecting them and see if it will at least POST or attempt to go into the OS.

WARNING: Before checking the capacitors, disconnect the power cord on your system and press & hold the POWER button to allow the power to discharge! Also, you should always ground yourself before touching computer components to prevent static discharge!

Just FYI, some of the motherboards in this series of HP&#8217;s have issues with the capacitors.

You should take a look at the capacitors to see if the tops of them are raised or discolored. Also, if you put your finger on the top of the capacitors, they should feel as if they are INDENTED and not flush or raised. Raising or discoloration (up to and including a black tar looking substance on the tops indicate a leaking capacitor).

Desktop 2:

Any POST sounds (beeps) produced at all?

Have you tried the monitor from Desktop 1 on this one?

Anything at all displayed on the monitor, to include CHECK CABLE message?

Recommendation: Open the case again and ensure that all the cards, memory, drive cables and so forth are all connect properly and not loose or dislodged.

Do you know how to RESET your BIOS to default using the onboard jumpers?

Trying to build a system for my brother. I put the 3200+ Athlon XP CPU in and with the heatsink. It turns on for maybe a few seconds and then turns off.

People were saying heatsink but I have tried it on 2, one is the ALK-800A, then some CoolerMaster one. I have to admit the CoolerMaster was originally from my 2100+ setup but still, it's all copper.

I do notice when I remove the CPU, it stays turned on. I know pretty sure this CPU works as I tested like hours before I put it in my brothers. Cant do that now since it was a quite a drive back home from college.

Referring to a Toshiba Tecra 9100, model no: PT910E-602SF-EN

The power button normally doesn?t turn it on at all, though occasionally it boots up normally, starts to load windows, then always cuts out after 5-15 seconds anyway.

It still charges up the batteries fine, but won?t turn on. I?ve checked the ram, hard-drive, and I re-set the bios to defaults - nothing stops it from cutting out if you can get it to turn on.

Any ideas what could be the problem? Any help appreciated, it?s the second time one I?ve had - the same problem last time!

Thanks

Hey,

Have you already tried cleaning the fan? Maybe a lot of dust is blocking the fan so the notebook can?t start and turns off itself due a higher temperature. It would be worth a try cleaning it.

But in my opinion you have everything done what you can do and it looks like a mainboard malfunction. If cleaning the fan doesn?t help I think the mainboard is defective or something else. If you are familiar with notebook disassembling you can try to repair it yourself with second hand parts. Otherwise it?s time for a new notebook I think?

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

Hi guys,

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.

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.

So, I installed Vista yesterday and it was working like a charm and last night I turned the computer off.

I woke up this morning, pressed the power button, lights/fans/computer came on for a few seconds (3 seconds approximately) and then the computer just shut off instantly, then another 3 secondsish later it turned back on and did the same thing, and it keeps doing it.
The only way I could fix it was by unplugging the power cable and turning off the switch at the power socket, I thought it may was a one-off thing.

I left the computer on, got back about 6 hours later and the computer was off (nobody turned it off, no power blackouts etc), I turned it on and it did the same thing. So I had to turn it off at the power etc and it boots up fine and it works.

This wasn't happening until I installed Vista.

Thanks in advance.

A:Computer turns on for a few seconds then turns off [loop]

I just realised, I haven't been shutting the computer down, just been clicking the power button in the Start Menu (which I have just realised isn't shut down - hovered over it: Keeps your session in memory and puts the computer in a low-power state so that you can quickly resume working). I'm fair sure this is "Sleep" (Vista noob).
I just went into Power Options and saw that Sleep was set to 1 hour, so I'm assuming:

* Last night I put my computer into sleep
* Today it went into sleep by itself (after 1 hour)

Therefore it's a problem with the sleep mode?

A:Computer power issues ! turns on then off turns on then off ...

Dear Customer, Welcome to the HP Consumer Support forum. In order to isolate the issue, please try and perform few basic steps as follows: 1. Open the hood and ensure the 4 or 6-wire power supply cable is seated into the connector on the system board2. Check if a device is causing the problem by removing ALL attached devices (such as hard, diskette, or optical drives, and expansion cards).3. Power on the system.4. If the system enters the POST, then power off and replace one device at a time and repeat this procedure until failure occurs.5. Replace the device that is causing the failure.6. Continue adding devices one at a time to ensure all devices are functioning properly.7. Locate the header and jumper labeled CLR_CMOS8. Remove the jumper from pins 2 and 3.9. Place the jumper on pins 1 or 2.10. Put the jumper back on pins 2 or 311. Replace the access panel12. Reconnect all the disconnected devices one by one and then power on the unit and check if the issue persists. In case issue persists please get back to us and we would be glad to assist you. Hope this helps, for any further queries reply to the post and feel free to join us again. **Click the KUDOS star on left to say Thanks** Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,GR1Although I am an HP employee, I am speaking for myself and not for HP

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.

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!

Help me, Obi Wan Kenobi! You're my only hope!

Mind if I ask what steps you've taken so far?

When I'm watching videos, they work fine but usually, Javascript turns off, which means that I can't watch videos again. I basically have to end the internet process and open it up again or just open up Firefox.

This problem only occurs with Yahoo's IE Browser.

Yeah, can I turn on JAvascript by any chance?
 

A:Javascript turns off randomly (I think)

JavaScript has to be enabled in any browser. To see if it working in your browser(s) go to this test page with every browser you have (one at a time of course!);http://www.javatester.org/

Click on the 'JavaScript' box on the left hand side and, if JS is working, a box will open confirming that and identifying the browser and the version of JS it is using. The version of JS varies with each browser, IE uses 1.3, Firefox 1.7 and Opera (my default browser) 2.1.

If you need confrimation that Sun Java is installed and working, you need to click on the box at the top of the tester page and then on the 'Java Enabled' box on the left.

I know there is a topic that addresses this already, but I have some computer-specific questions related to the procedure/advice that is given in the other thread. I have a IBM ThinkCentre 3.0Ghz machine that is randomly shutting itself off. It appears to be an overheating issue. The other post recommends checking the fans. I see two fans in there (they both work), but does anyone know how many fans there are in this machine (it's a tower). Is there a hidden fan that isn't working or is it just the two I can see? Second, if the heatsink has a thermal pad, do I still need to apply a new layer of thermal paste? Third, what temperature should a computer run at? The other post included a link to a diagnostic tool, but I don't have any benchmark for comparing my computer. Also, if the computer shuts down when it gets hot, how can I use the tool?

Thanks for your help!
 

A:My computer turns itself off randomly

computer shuts off randomly

Do you mean that if I just leave the computer sitting there after it has shut down, it will turn back on after 5-10 minutes? When the computer does its "I'm turning myself off in the middle of a process" routine, the mouse, keyboard, harddrive, all that junk turn off, but the power light remains on. Will it restart after it cools down? Also, when I try to restart the computer, it will get to the desktop, then shut down. It does get by the BIOS and loadup screens, though. Is this normal for an overheating issue? Finally, what kind of issues could it be with RAM? Are there any tests/diagnostic tools to check?

Thanks

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.

Hi, ive been having this problem for a while but it is not constant. My computer will simply turn off randomly. Sometimes i can go for hours and hours of gaming and it will be fine so ive ruled out over heating as an issue. It was suggested that maybe a slot of RAM had become faulty causing my computer to turn off.

Today i decided to test my RAM by running high demanding programs hopefully causing my computer to switch off. Then i would take out a single slot of RAM to see if that was the problem. The thing is ive been running programs all day and my system hasn't shut off once. I know should be patient but to be honest this is taking the piss.

If anyone has had this sort of problem and could share some information on what may be causing the problem then 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.

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
