PC Shut Down Then Restarts By Itself - How To Diagnose
Nov 10, 2011
I bought a used PC as a backup for my kids when they come home. Seems to work fine but one in a while will shutdown by himself and restart. PC is an HP Pavilion a6318
- I did pass the memtest with no fault for a complete day
- I did check the inside, there is no apparent accumulation of dust
- I did test the hard disk and no fault found
- Fans are running. No evidence of overheating
- Did a Virus and Adaware test
What other test could I execute?

I have had my laptop (Dell Inspiron N7110) for less than a year, and everything has always run smoothly. I performed a format of my hard drive yesterday and installed a clean copy of Windows 7 Home Premium. Everything went fine with the format process, so I didn't think anything was amiss until I tried to shut down the laptop before going to bed. And that's when I discovered that it won't shut down, unless I physically hold down the power button (which I don't like doing, for obvious reasons.) If I choose the "Shut Down" option from the Start menu, the laptop goes through the "Shutting down..." process perfectly fine, but the laptop boots up again immediately upon turning off. So it's like instead of shutting down, the system just does a restart. Which is fine for some things, but I do eventually want to shut down my laptop (I don't like leaving it on overnight in case there's an electrical storm, for example.)

I have windows 7 professional 64bit and it won't shut down by it's self - it will just restart. I had the RC version (64bit) earlier and that did the same too. I used to run vista (32bit) on the same machine/hardware and that was fine. Any ideas what might be up[CODE]

For the past week, my recently new started having this problem .Whenever I try shutting down the computer, click start and shut down or shut down on the log on screen, the computer turns off for 3 seconds, then restarts.I've google searched the problem and found solutions such as changing registry key, creating a shortcut on the desktop and clean booting but none have worked for me.

I have a DELL XPS 17 Laptop. Windows 7 Ultimate x64. Recently my laptop has been restarting itself when I shut it down. It would shut down normally but after 1 second, it turns on by itself. I've checked "events" and I have "Event 41 : Kernal Power".

I have just bought entirely new system about 4 months go or so, this has been a self build. The issues first had was whenever i select to shut down windows it starts shutting down and as it gets to the point where it actually is supposed to turn off it suddenly blue screens and then goes into a restarting boot! this is hugely frustrating as when i select shut down i want it to shut down not blue screen and restart. I formatted my machine about a month ago as the issue was getting extremely repetitive, once formatted everything worked great until just the other day it started again it is not as frequent as it used to be, it only happens once every 2 weeks or so. I know its not viruses as i run KIS and malwarebytes and regularly scan the system for any issues, i dont think its hardware because the system is new and i have used the best parts, also i dont think it is frequent enough to be hardware.

I attempted to upgrade my Vista Ultimate x64 to Win 7 Ultimate x64 yesterday and the upgrade process failed.
The install rolled back to my Vista install and all is good, but I really want to upgrade to 7 (and not do a clean install)
Can anyone help me out with how to diagnose what may have gone wrong with the upgrade? Is there an install log file somewhere that I can have a look at to discover the problem?
I think I may know the source of the problem, but would like to confirm it before moving forward.
The upgrade did tell me that my Silicon Image RAID controller may not work properly after the upgrade. But I don't have any drives connected to it. My system drive is a RAID 0 array on my Intel ICH8R/ICH9R SATA RAID controller.

Over the last few days I have been getting random and very intermittent BSOD's for the first time with Windows 7 x64.
Each BSOD during the memory dump before rebooting was making a reference that it couldn't start up my video driver or something in that nature. I have a nVidia evga 9800 GX2 with 190.37 drivers.
After a BSOD this morning, same reference as above, windows rebooted but resolution was 640x480, a quick look under device manager showed both GPU's on my 9800 GX2 had been stopped due to a problem with exclamation marks beside them but oddly I still had a display.
After the next reboot, I couldn't get into windows anymore. Not windows 7, or XP, or leopard (I am Triple Booting) I CAN however get in via safemode but my troubleshooting is not revealing much cause in safe mode, those drivers are naturally disabled.
The event viewer under administrative tools, showed a kernel-power reference during my last couple BSOD's which I believe is just me hitting the reset button when the computer was freezing up. There are no other critical references.
My initial thoughts is that something in the video card was slowly beginning to go, hence the casual BSOD's over the past couple days and now that's it. BUT the odd thing is that ALL the LED's on my video card are showing correctly, ie, if there was some kind of internal problem, there are a couple of them that should be showing red or yellow, but they are not.
Anyone have anyway of diagnosing that it is indeed my video card that is failing? Could it be the motherboard? Also, in safe mode in Windows 7, I tried reinstalling the 190.37 drivers but no changes.
Thoughts? Questions?
PS - I have tried startup (repair) and I have tried restoring to an earlier point. No changes. I am still in safe mode.

I've had a computer running rock solid for about 18mths. I've just used ~70% of it's parts to build a new computer for my dad and since then he's been experiencing constant BSODs. The computer is running a freshly installed over-the-counter bought OEM copy of Windows 7 Home Premium x64 which is up to date as of last week. It will run fine for an unpredictable length of time between 15mins to half a day then BSOD. Sometimes it will then get stuck into a "crash-reboot" cycle and he will have to hard power it off.
The computer is less 18mths old. The parts I have been using confidently over the last 18mths are as follows:
- MOBO: Gigabyte P55-UD4
- CPU: Intel i5 750 quad core (never overclocked).
- RAM: 2x(DDR3 2GB G.Skill 1333mhz)
The new components we installed are:
- GFX: Asus ATI HD5550
- HDD Sata 200GB Baracuda
- CD Drive: LG DVD writer on an IDE ribbon
- PSU: Antec VP450P 450w
I initially had an old install of Windows 7 on a 120GB Sata drive but when he started getting issues I installed a brand new OEM Windows 7 on the Sata 200GB and even changed the Sata cable. It ran fine for a day then started up again. From what I could see none of the crashes pointed toward gfx drivers - however I've noticed CPUz will only tell me that it's a HD5500 series card and gives me no other info so maybe it isn't being recognised properly . The only other thing to change was the PSU - which admittedly is a budget one (but from reviews should be reasonable) from deduction it's the only thing I can put it down to.

So one of my friend's laptop had been acting slow, and I took a look at it and I cleard out some applications but it was still going bad. it turns out the hard drive had to be replaced, so he sent it in under warranty. I reinstalled Norton 360 and Office for him, and helped him reinstall some of his games.Then i found out it was acting slow again, and was practically unusable for gaming!He's coming down this weekend, and I plan to take another hack at it. But I don't know what the cause would be. it's a new hard drive with a new factory image. I suspect that the new hard drive might be faulty, but I don't know how to test it. I do have some spare hard drives around that I could install, but I'd like kto know what testing processes or programs I can use to better diagnose the problem.

Every now and then my computer shuts down then restarts on its own. I notice that any usernames and passwords that I have set to remember are reset. I get this error in my event viewer I don't know if its related :
"Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected".
OS: Windows 7 Ultimate.

About a week ago my PC had restarted on its own when I wasn't there and was stuck on a screen saying "Reboot and Select Proper Boot device or Insert Boot media in Selected Boot device and press any key ". I manually restarted the PC but nothing was shown on the screen. I turned off the PC, disassembled it and took out the BIOS battery and left it there for about 30 minutes. I then put everything back together and booted. The PC started fine but after about one hour it crashed for no reason. Since last week sometimes it crashes or restarts either within minutes from logging into windows either within an hour but never over 2 hours. At first I though it was a power supply issue, I had a Corsair VX550W for the last 4 years and so I replaced it with a brand new Corsair TX650, this has not solved anything though. But since I replaced the PSU the PC now only restarts every 1 hour when I am logged into windows. However, at this moment I have left it open into BIOS and it is working for 2 hours without any restart.

I started having this problem about 2 hours ago, when suddenly my laptop that worked perfectly fine for nearly 2 years just rebooted itself. It is now rebooting about every 5 mins and I can't do anything about it. I tried to start it in safe mode and it did not reboot.

I wanted to upgrade XP to 7, I've upgraded it partially when in XP. So now XP is no more, and I only have to boot from the DVD.But now I have the problem:Every time I insert the Windows 7 DVD the pc says "Press any key to boot from CD or DVD..." (as normal), When I've pressed the any key, the PC does absolutely nothing and just restarts.After that, I fiddled around in my BIOS, "turned a few switches", made a copy on a fresh DVD. Now when I insert the DVD, the PC says:Press any key to boot from CD or DVD...When I've pressed the any key the PC says:Press any key to boot from CD or DVD...When I've pressed the any key the PC does absolutely nothing, no reboot, no loading, no next screen, no nothing, altough the underscore flashes trougout the whole time.I've cleaned the pc from the inside, (with a vacuumcleaner), opened the CD/DVD player, blowed air in it so the dust could come out... Nothing works...Could someone please tell what's wrong?Is it the DVD? Is it the DVD-player? Is it the motherboard? Is it because my keyboard does not have the any key? Is het something wrong with my BIOS settings?

I recently installed windows 7 64-bit ultimate using a clean install since i had windows xp. Everything installed ok. The problem I'm having is that when i shut down, it automatically restarts instead of shutting down. It runs through the BIOS and POSTS as if i restarted. There are no errors listed when it restarts. It's as if i pressed restart instead of shutdown. The only way i can turn off my computer is when i hold down my power button for 3 seconds.

I have CD-RW's and I like to know I can use them to recover my laptop failure system. My problem is that I can't access my desktop,Dell XPS. Its just restarts at the booting process. I think its a virus that is causing it. But I also want to restore my computer to its original factory position. How can I resolve this without going into the desktop?

I've just moved flat and after I did my computer keeps rebooting itself every so often. There doesn't seem to be any reason to it. I've check that all my fans are still working and that all the cables and cards and what not are corrected install and that something hasn't been knocked but everything seems fine to me. I had a wee gander round the internet and it pointed me to check my system log and the two error codes I'm getting every time this happens is: Event I.D 41 + Event I.D 6008. The I have just recently got a new Graphics card, 4gb extra of ram and a wireless adapter. These were all installed on a clean version of windows 7.

Today, 5/1 I received quite a few win updates to install. After installing all my PC started restarting itself every few minutes. I went to system recovery and to the restore point created and then all was OK. I installed the updates a few at a time until I was able to recreate the problem and then narrowed to KB 2506014 for W-7 x64 based systems.

Whenever I go to the "Programs and Features" module in Win 7 I get the trusty old, "Explorer has stopped working and is restarting" my taskbar goes for a split second and P&F closes. I have gone to Event viewer to look for a reason and 9 out of 10 crashes acording to the faulting module is "msi.dll" Isn't msi the Microsoft installer? Anyway, how can I go about fixing this or troubleshooting it? It is to say the least annoying. My Computer is an Acer laptop Win 7 HP x64/8gb RAM /Core i5 430Mprocessor.

I bought a HP P6510f PC about 1.5 years ago. In the past month the computer started having problems. The first sign of problems was powering on and the computer would not boot up but instead go to a blank screen with a flashing cursor in the top left corner of screen. I ran a diagnostic through the internal software, I believe it's called PC Doctor and all componenets checked out fine - RAM, CPU, Hard Drive, etc. I then decided to reinstall windows 7. After installing the computer started to work like new again, except the next day it restarted itself and went to a black screen. It's done this a few times now. Sometime it boots up fine, other times it gets stuck and won't boot, just a black screen or the HP screen welcome screen with option for setup f10 (though won't respond).
Are there ways I can check for internal malfunctioning hardware?I did go into event viewer and noticed a few errors under System and Application that I have pasted below Critical - Kernel 41 power "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Error - Event 20 - Installation Failure: Windows failed to install the following update with error 0x80070643: Security Update for Microsoft XML Core Services 4.0 Service Pack 2 for x64-based Systems (KB954430).Also, this shows up as "error" - "The previous system shutdown at 12:37:29 AM on 12/31/2011 was unexpected" [code]
