PC Randomly Shuts Off And Randomly Boots Up After (sometimes)?
Mar 7, 2012
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.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.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 Windows 7 install from late Jan.

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 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.

I just went to Windows 7 on my laptop, got the 'quick-launch' working but when I click on one of the icons that icon disapears. If I start up a browser lets say, and I need to open another browser window I can't use the quick-launch cuz that icon disappears as soon as I opened the first window.Same with all of them, including 'windows explorer', one window and the icon disappears, is there a way to get them to stay?

so I had this homemade computer, the specs: [CODE]and after I uninstalled linux from my Ubuntu-Seven dual boot,I used the MBR and boot command in the ERD to fix my bootloader so I can use windows. but after a while, it started powering off randomly, even when I was using it. then when I switch it back on, it says windows was shut down improperly, making me think it's a hardware problem. I've tried RAM test,

For the past month or so, my laptop has been randomly shutting down with no warning whatsoever. It doesn't even restart, it just completely turns off. I can be doing anything and it will happen.
At first I thought it was overheating but then I installed SpeedFan and it's still doing it (and I can tell from feeling under the computer that it's no longer overheating).
I've run virus scan after virus scan (Malwarebyetes and Microsoft Security Essentials) but it's not finding anything wrong with my computer.

ver the past year I could say I have been been getting a lot of random shutdowns with my Dell Studio 15. This can happen when I'm browsing the web, trying to play a game, or I leave my laptop on for a extended period of time (a day or more). I realize a year is along time to wait to solve a problem, but better now than never. My laptop is a Dell Studio 1555 running Windows 7 x64. Sometimes when I turn my laptop back on I can hear the fan running rapidly, yet when it shuts off I do not hear it. I believe these are due to heat and I just need to clean out my laptop. If and when I leave it on I come back to find it has restarted and most of the time there is a not a Blue Screen notice. Usually in this situation I just left my laptop on or I am streaming media. Sometimes it will Blue Screen but most recently, within the past few months it has not. Today it actually has produced one. Unfortunately I believe most logs are deleted due to my use of CCleaner and TuneUp Utilities, but I do have Critical events in my Error Logs which date back to 2 months ago.

The PC happens to be shutting down on its own and worse thing that frightens me is that it does not switch back on for at least the next 30 mins or so .. something like a cooling period.. I'm pretty sure that it may not be a heating issue because this shutting down does not necessarily happen when playing graphic intensive games.. happens sometimes when I leave the PC unattended or when there is just some mp3 playing on it.. hard for me to diagnose the root cause. The event viewer in control panel (which is something amazing in win 7 for troubleshooters !) seems to be capturing too many errors / warning / critical events. These shut downs happen to be critical events.
The log from the most recent shutdown last night is as below.
Log Name: System
Source: Microsoft-Windows-Kernel-Power
Date: 22-07-2012 09:53:32

So I found my old copy of Tony Hawk's American Wasteland (OLD game) and I decided I wanted to experience some nostalgia.I installed it and everything and it started like a charm. Once I started playing, my computer randomly shuts off. Just completely turns off, no warning, nothing.I'm pretty sure that my computer is not overheating because I play StarCraft II on this computer and do not have any overheating issues. This Tony Hawk game is a much lighter game, taking much fewer resources.I have an HP HDX18 laptop computer. url...I probably need to provide some other stuff to aid in finding the problem, but I do not know what else to provide.

I am having a big issue with my computer. I originally ran windows xp professional until i upgraded to adobe cs5 and needed to switch to windows 7.now that i have windows 7 my programs stop working constantly. if i'm working in photoshop on a large photo the screen will go blank and a bubble will pop-up saying "driver stopped working but has started working again" and a lot of times photoshop, illustrator, and FL Studio will stop working and need to be shut down and started again. i've noticed sometimes when the computer is on overnight i'll wake up and it will be off. when i turn on the computer it will say that it didn't shut down properly. i was in the process of doing batch photo edits and it shut down on me right in the middle so i've got to figure out the problem. since i use this computer for freelance graphic design and photography. here are my specs.

Running Win7 64 bit, built this computer back in December, has worked flawlessly until now. Last few days - operates fine for an hour or so, then freezes, goes black, crashes and reboots itself, only to stop at the loading OS screen due to 'Boot Disk Failure' Happens regardless of what I am doing, or even if idle. Have updated windows, ran virus and malware scans.
GIGABYTE GA-Z68XP-UD4 LGA 1155 (it was slightly bent on the end with the USB connectors and headphone jacks, but installed fine)
GIGABYTE GV-R697OC-2GD Radeon HD 6970

Intel Core i5-2500K Sandy Bridge 3.3GHz

8 gigs Ram
All Critical errors are event 41, Kernal Power - but I'm sure thats from me hardbooting on the disk failure.

I use Windows 7 Pro on my Sony VAIO Laptop and I have noticed in the last few weeks that it has became slower and slower so I did the defrag, virus check, disk clean up, windows tweaks and tips un-checked most of the start-up programs and it did make the computer faster except for the boot and shut down and the average time is around 3 minutes for both, so what else can I do before I decide to reformat and set it back to factory settings

When my system is working, it will occasionally just shut off. No BSOD, no error screen of any sort, just a clean power off. It happens anywhere from twice a day to once every two weeks. My system specs are located below.
When my system is not working, I can't even get Windows 7 to load. It boots, I get the option to repair (which, only the first time, will say it reverted back to a time when everything was working fine) or start normally. If I choose to repair, it restarts, then goes into the infinite loop. It restarts, if I choose repair, it says windows cannot fix the problem, and shuts down. If I choose start normally, it shows the windows loading graphics, but then I get the clean shut down right before I get to the log-in screen (don't actually ever see it).
How does it go from the first scenario to the second scenario? Well, I think its Microsoft Office. Every time I try to install it (sometimes successfully), I eventually start to have these start-up problems. But I can't be certain, I just downloaded a fresh install file today to make sure it wasn't my DVD. There are so many more details that may or may not be important, but I'll spare them for the time being.
This is a home-built computer. It should be noted that I've had this problem mostly through the life of this system (15 months), and have replaced the power supply, the RAM, and the SSD that the OS is installed on.
P55A-UD4P Motherboard
Intel i7 870 CPU
16GB Kingston 1600 RAM
OCZ Agility3 120GB USB 3.0 SSD
OCZ Agility2 60GB USB 2.0 SSD (Used for my Star Wars install)
Nvidia GeForce GTX 460 1GB
Corsair GS700 PSU
Windows 7 Home Premium
Microsoft Office 2010 Professional
I realize the shut downs sounds like a overheating issue. I wish I could go check the temperatures to let you know what it idles at, but my computer won't turn on. However, I play Star Wars: TOR at max settings and have never had a shut-down happen during that time.
I know this is a shot in the dark, but I don't know enough to narrow the problem down. It honestly makes me want to go buy a pre-built because I feel like the problem is my choice of components or some type of incompatibility.

I have had this computer for just over a year and it has ran like a top. I was surfing the internet last night when it just shuts off (no slow down no blue screen) and boots into startup repair. It would not repair, just sat in there forever and would not boot into safe mode or anything. It just kept booting into startup repair for hours.
So I hit esc when it booted to startup repair, I go to the dell backup and restore, save my work documents and pics and let it boot to factory fresh windows install from the dell created partition. Windows reinstalls and loads fine, boots in and begins to update successfully and then reboots back into repair. This happens everytime it reboots. After sometime it will boot into windows fine. If I restart I am back into startup repair for half an hour or more.

Normally this is triggered by a video, but can happen with a number of programs including Windows Explorer. When this happens my PC goes VERY slow for a few minutes.

There seems to be no pattern as to when I get a BSOD. I ran Memtest86+ for about 18 hours (8 full cycles) and there were no errors. I've noticed also that anytime I run Prime95 with high FFT lengths, all 4 cores fail almost immediately ("Rounding was 0.5, expected 0.4" is a common one). I have gotten BSOD's when nothing was overclocked. I've gotten it when doing light overclock stress testing as well. I've gotten it when doing no stress testing and nothing else that's CPU or memory intensive.

Lately I've been getting BSODs randomly during the day. I work from my computer at home and then sometimes also play games at night like Mass Effect which is pretty system intensive. Whats strange is that the BSODs only happen when I'm working. I have 2 browsers up, a text editor maybe 2, ftp program, sometimes music. Nothing that would strain the system.I've ran driver verifier already which lead me to remove my Realtek HD Audio driver, I've turned it off since. I ran memtest86 overnight once and will run it again for a more extended period, but because of when the crashes happen I'm inclined to think it's a software issue.

My PC keeps getting BSOD's at random points during use though I'm thinking it could be hardware, but was hoping to get some expert advice before coming to that conclusion.It started happening a while ago and created quite a few minidump files, though tonight I think I reset the CMOS (couldn't boot PC) & went into windows, the date/time were reverted back to 2002 & the minidumps were no longer there (even after adjusting the date/time back to normal)I have 2x dumps at the moment & hope they are of some use.(attached). I had to add .doc to the end of the .dmp files. The upload manager wouldn't upload the standard .dmp file.There's no specific point at which it would BSOD, sometimes PC would just lock up without the BSOD screen showing up. Could happen within minutes of turning on, or an hour+ after. Could be watching a movie or surfing the net.. or just sitting there.

As the title already says, I'm having problems with my usb slots not working sometimes for my mouse and keyboard, they either stop working for a few seconds and I get the windows "connect/disconnect" sound or they just stop working which can be fixed by repositioning the 2 usb's into a different set of slots. This solution however only works for a while until the same problem occurs again and I have to reboot to get them working again, this problem nearly only occurs with the rear usb slots, it does, however, somethimes affect my front 2 slots where I have a headset plugged in, this is noticeable immediately as any sound heard from the headset is wrong (can't really explain how it changes ). I have already tried uninstalling/updating drivers and turning on legacy support in the BIOS but to no avail.

Just recently my mouse keeps randomly going off and I have tried it in the 4 front usb 2 ports in my computer and it works but still randomly goes off for a millisecond and in the back usb ports it doesnt work at all when its working it sometimes affects my headset when the mouse goes off and the sound will be really weird and eventually revert back to normal.
I noticed when I went on control panel -> devices and printers my pc had an error symbol on it so I tried to troubleshoot it by using the option when right clicking and it says needs to install 'usb controller driver' and I let it try and find it but it said it failed because it couldn't find it and I can't find it anywhere if anyone can link me to it I would be so happy to get my mouse sorted out.
