Computer Randomly Turns Off (no Reboot, No Error)?
Aug 31, 2012
My computer will randomly turn off. Only if I am using it. I can turn it on and it will sit forever, but if I use it.Shuts completely off with no warning, no error, nothing. I need to power it back on by pressing the power button. I went to CMOS and turned on restart on system failure and it does not restart. Don't think it's running hot.. at least, my gcard is only doing 48 C which is low. Idk if it's a software issue or hardware?I ran a scan of my computer using ESET NOD32 Smart Security = nothing found.

Okay, so a while ago I finished building my new Pc. It was working fine for about 3 days but then it would randomly go black and show the message, "Please select a proper boot device and press a key". Prior to this I had accidently been turning off the power to my computer (it was in a weird position, so when i stretched i would kick the cable). Could having turn off the power caused this? I only did this twiceI also tried connecting it to different sata ports and nothing

I'm having some problems with my computer shutting down randomly. No BSOD. I just reset the BIOS and removed a single GPU, so I am no longer in SLI mode.

I have this problem with a Packard Bell Desktop computer, It randomly crashes when doing startup, I dont know if its the motherboard, or the HDD. But it crashes after 4-5 min of driving, it starts up at BIOS Screen, with 3 beeps and then it goes to windows startup restore, and it cant startup windows either. So im trying at the moment to format the computer, but it gets the the "Windows Is Loading Files" At the second part of it, it gets half way in the loading, and it random turns off, and it keeps happending all the time, I dont know if its the HDD, or any Hardware Problem in the BIOS, or GPU

It freezes everytime i put it into sleep mode, and also when i reboot it. In sleep mode, the monitor turns off, but the computer continues to run (fans and lights are still on). I at first thought it was a PSU issue, but then it started to hang during games and it also freezes while booting the computer. The first time it froze mid-bios, then it froze a couple of times after the bios (when loading an OS), and it is now frozen on the windows boot screen (The logo and "Starting Windows").

Over the last couple of days my computer randomly freezes and i have to force reboot it happens at random. So I checked the event viewer and it said The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

I have one question regarding Windows 7 firewall. Few weeks ago I installed KIS 2009 Technical preview on my Windows 7 RC. During installation KIS disabled Windows 7 firewall. After trailing KIS for a while I decided to uninstall it. I uninstalled the program and rebooted the machine. After restart my Windows 7 firewall was turned off (KIS didn't enable it during uninstallation?).
So I manually enabled the firewall. But now after each reboot firewall is turned off and I have to manually turn it on. I even tried to reinstall KIS and uninstall it again but it made no difference. Did KIS screw something with Windows 7 firewall or is this just Windows firewall problem?

Last week I took my laptop into Best Buy for a diagnostic due to some issues. After I picked it up, I noticed that every time I restart/turn on the computer, the wireless adapter turns on for a couple of seconds then shuts back off, and I have to manually press the adapter button twice for it to turn back on. I've never had this happen before.... and I reinstalled the OS last night at the recommendation of Best Buy because of the other issues, yet this adapter thing is still happening. The wireless works perfectly fine after I turn it on, but normally my adapter turns on automatically.
Does anyone know why this might be happening and what I can do to fix it? Right now it's just more of an annoyance that I have to turn the adapter on every time, but I'm worried that means something is wrong? Like I said, this didn't start happening until a week ago.
The laptop is an HP G60, running windows 7 home premium. The adapter is an Atheros AR5007.

Since about 1 month my PC turns randomly off. Sometimes after 10 hours, sometimes after 2. Mostly when in Idle or when I'm watching movies on a second Monitor (TV but it also crashes if it is unplugged so thats not the reason). Sometimes when I try to boot again it wont start except if I turn off the PSU for ~15 seconds. Sometimes when I reboot there's an error message "Asus Anti Surge was triggered".
I already tried:
- Replaced my OCZ ModXstream 600w with a Corsair AX750 PSU
- Stock settings in Bios
- Asus Anti surge deactivated
- Changed the power outlet to another one
My hardware:
i5 3570k @4,3 GHZ
Asus Sabertooth Z77
GeiL Evo Corsa 16GB
Sapphire AMD 6970HD
2 Harddisks 250/500gb
1 SSD OCZ Agility 3 120gb
And like I mentioned 2 different PSU's.
OCZ ModXstream 600w
Corsair AX750

I've had a shuttle sk22g2 v2 system that I leave on and sometimes find turned off and occasionally see a BSOD when using. The BSOD happens randomly, flashes on the screen for about 1 sec, and then turns off the PC. I've had this issue since doing a fresh install of Windows 7 ultimate 64 from window XP 64.I don't know if it is related, but I also had an issue where my on board NIC would stop working. I tried fixes from installing different driver versions, restarting services, and restarting the NIC. The only thing that would recover would its functionality be restarting windows. I added a NIC card and that has allowed me to keep network access.

i am able to turn my computer on for a few seconds but then it automatically shuts itself off after a few seconds but the thing is after letting it sit for a couple seconds it says something about how the clocks on my processor have been overclocked too high and asks if it wants me to restore them, so i do that and then the computer works fine, but then when i turn it off and turn it back on it does the exact same thing until i get that message again.i've tried manually reducing the clocks on my cpu even though they were already at stock clocks and that didnt work
system specs:
windows 7 ultimate 64bit
intel core 2 quad q6600 @ 2.4ghz standard clocks
4gb ddr2-800 ram

I have rebuilt my system twice now and my system is still turning off the display and powering down randomly. I have followed all the guide lines for disabling sleep mode and it still randomly stops running by turning off the display and powering down. I have to push the power button again and then Windows start up in diagnostic mode where I can select safe mode if I want.

I'm not sure if this is the right section to post this but, ever since I reformatted my laptop, it randomly freezes for about a second and a stuttering noise comes up. Then the screen turns black. It doesn't shut off because I could see the back light, it just turns completely black. What's causing this problem and how do I fix it? I checked the Event Logger and there are tons of errors and some critical kernal-power things.

My computer has been running fine for about a year, I have reinstalled windows 3 or 4 times and I haven't had any major problems. During this last re-installation I formatted my hard drive to get all my space back, I'm not sure why but since I formatted my hard drive windows randomly freezes and It isn't during any specific program so I don't know what could be causing it.

I am also using BlueScreenView but I don't understand the codes for this to know what is the cause. SEQUENCE OF SYMPTOMS: First application I am on freezes, cursor is waiting (cursor freezes and resumes, then freezes again). Windows Explorer freezes as well (turning white and then disappearing to only desktop wallpaper). All application closes as if it were restarting. Error windows pop up for applications, such as C++, security programs, browsers...
BSOD.

Ok, so I am going to try to explain this as thorougly as possible while trying not to sound like an idiot in the process. I am by no means computer savvy so anyone that has any advice will more than likely need to talk to me like a 5th grader. I am ok with that. Since installing a Windows Update about a month ago, my screen will randomly lock up. At times it will clear itself after a couple of seconds and state something to the effect that "display driver amd has stopped working and recovered." Other times it will stay frozen for about 10 minutes and then will start functioning properly again. More often than not though, it will stay frozen indefinitely and require a hard reboot. This happens during mundane activities. No extreme gaming going on. Generally it is while just browsing the net. It tends to happen more often to my wife who uses it during the day to work through a VPN. I don't believe there is any correlation though. I have read multiple forums on the web and have tried several things, from cleaning the registry to uninstalling the driver software and reinstalling it in safe mode. The latter seemed to work last night but today my wife started having the same issue again.

I have 4 Win 7 computer that will not up-date, Windows shows 21 updates available (all 4 computers show same), upon reboot system says "Updates Failed". Each computer upon reboot dsiplays an error message saying the "updates failed". rinse - repeat.This started with one computer about a month ago, I now have 4 that are doing it. I have scanned with Combofix, Superantispyware, Rkill, Symamtec's Endpoint, eSet on-line, Panda on-line, Malwarebytes, JRT, ADWcleaner, CCleaner, FSS, awsMBR, and tried the MS FIXIT.
I also tried this procedure:
1) Disabled Windows update Service
2) Deleted all files in c:\windows\softwaredistribution\datastore and deleted files in c:\windows\softwaredistribution\download
4) 3) Downloaded and installed the most up to date Windows Update Agent.
5) Restarted Windows Update Agent, made sure Workstation and Background Intelligent Transfer Services were running.
6) Ran the MS Mr. Fixit program to repair update issues.
7) Ran the Windows update. 21 updates to install (as always).
8) Rebooted
9) Guess what, same issue!
I tried this on ALL 4 COMPUTERS I have with this SAME issue, 2 of which are on the same domain, the other two are laptops. ALL 4 FAILED. All four (4) again show the need to receive 21 updates. All 4 were again ran through the update process, all four (4) again failed post re-boot to take the updates (message stated �up-dates failed� post re-boot)

My first guess was that since we have an electrical instability in our home, perhaps the uneven flows of power would sometimes send a false signal to the power unit of the computer and trigger a start-up (quite often the lights in our home will briefly, and sometimes violently, wave up and down, especially at night).

I have just finshed building my computer and when I turn it on nothing displays on the monitor ! The case fans are running but theres no display. Also I noticed that when I turned it on the CPU fan would spin for a while then stop spin then spin again. I have tried to unplug the CPU fan and replug it back in and it still happens. Is it because of a faulty Mobo?

I am having a problem with a new installation of Windows 7 Home Premium. I have always liked the Hibernate feature and used it extensively when I was running Windows Vista Ultimate. Since installing Windows 7, whenever I run Hibernate the computer turns back on. When I used Hibernate in Windows Vista Ultimate I knew that the programs that I left open would be where I left off when I restarted the computer from Hibernate. Now, it just seems to turn on when it wants to. I am sure it is a setting in the Power Settings category in Control Panel. I'm just not sure how to set.
