[CRASH] Windows Locks Up After PSU Failure
Feb 26, 2011
I recently had a PSU failure and replaced with a new unit. System now powers up.
However Windows is now randomly locking up. No BSOD, no warning, it just locks and stops responding. No screen corruption either. The only solution is to power off. It never once did this prior to the PSU failure.
The lockups happen randomly, maybe after 20 mins, maybe an hour and have occurred when:
Internet browsing
Running a large Backup
Installing the new SP1
There is nothing in the event logs that suggests anything happening prior to the lock up. There are no heat issues.
To try to isolate the problem, I have: Run Memtest86 for hours with no problems and also the Windows memory test, all fine.
Run Prime95 for a while again with no problems. I am gonna do some more tests later in Prime to check cache specifically. Reinstalled Windows on different a Hard Disk and still get exactly the same problem.
I am now coming to the conclusion that the PSU failure may have caused some sort of damage either to the motherboard or processor. I am going to return the new PSU to the supplier and get a replacement sent out just in case the new PSU is at fault.

I've been getting random lockups for quite some time however here is the kicker,it ONLY happens with more than 4GB of RAM installed...anything less than 4GB I am perfectly fine but anything more my computer locks up totally randomly.Random bits of information: Tested all of my RAM sticks individually and in any combination I can think of,as long as the total is nothing more than 4GB I'm fine and dandy but soon as I hit 6,8,10(Due to what sticks I have I can only go up in multiples of 2GB) I get random lockups.Lockups can happen on desktop when I'm afk and the computer is completely idle,after 2 hours of intensive gaming killing splicers in Bioshock 2 or just while I'm transcoding a movie on the fly(This actually seems to be relatively safe,does not happen often)On the lockup whatever sound that was playing repeats(The last 0.2 seconds of it or something) so it sounds like BZZZZTTTTTT no matter whatNew motherboard,new PSU and hard drives passed a chkdisk recently(Albeit with some grumbling from them about bad sectors)SFC scan completed,no problems to report with my file integrity.PSU has plenty of power for the systemJust recently installed SP1(After the problem started) in an attempt to fix it,to no avail by the looks of the recent lockup and now I have no updates pending so windows is fully updated.
Obviously checkSUR ran with no problems before installing SP1Booting into an Ubuntu liveCD and running random stressy things for the computer does not produce the same effects,it runs perfectly fine.Computer temp is high but within an acceptable range most of the timeOnce it crashes/locks up once it sometimes does the same on boot again and again till I just leave the thing alone for an hour or two and try booting it up againEvent Viewer just shows this for each event when it locks up and I'm forced to reboot it manually:[CODE]

I have a Dell Inspiron PC that I got a few months ago, and everything's been going pretty well. I've had one or two BSODs, but nothing major. Now, though, I'm faced with kind of an issue.Whenever I leave the computer alone for some time, it crashes. It used to be where it would only do it sometimes if I leave it alone for hours (like overnight), but today it crashed while left unattended for just around 4 hours. When it crashes, the computer seems to be on as the power and busy lights are on (the busy light blinking occasionally), but there's no output on the monitor. I can't use the keyboard or mouse to 'wake it up', so I have to hard reset it with the Power button.After the hard reset, it powers up, but it displays that there's a "Keyboard Failure", and continues to boot up. I restart it again at this point, and then it boots up as usual. The keyboard is responsive, and it asks me if I want to boot into Windows normally. I choose to do so, and it runs normally.

A while back my computer crashed when playing ARMA2. I was playing and suddenly my screen turned black but the sound kept playing. I did a hard reboot and i got a Disk Boot failure. I decide to do another hard reboot and the computer turned on normally. After this i haven't had any problems any more.
Until yesterday when i installed a new game (Dishonored) A minute into the game the same thing happened as with the ARMA2 crash. Screen turns black but sound keep playing so i did a hard reboot. I got a Disk Boot failure but after a hard reboot it is gone again. But unlike with the ARMA2 crashes this happens every time i try to play dishonoured. I reinstalled the game on a different partition of the same drive and it stilled happened although this time it let me play for about 5min. But i don't think it had anything to do with reinstalling it on different partition it seems to randomly crash within 1-5 min.
I check a few other games and they don't seem to give any problems. I also did a chkdisk of the drive the game is installed on but no problems where found. I also did a memtest86 but also no errors.
My Windows is installed on a SSD but the game itself is installed on a HDD. don't know if that matters but i thought i just add that.
So is it the game or is it the drive ?

the last couple times I've sent my laptop to hibernate I have had driver power state failure BSODs. I usually have some programs like Chrome and Spotify open. I rarely shut down so I'm unsure if the problem is specifically related to hibernation.I have attached minidumps and updated my profile info with hardware specs.

I read through a few threads with similar topics but the issues were either not quite the same and/or resolved comparatively easily. I am trying to repair a 1.5 year-old HP Pavilion running Windows 7 Home Premium 64. This machine is used as the main office computer in a small doctor's office. In spite of my warnings, anti-virus software was not installed until it was too lateThere was a major issue about seven months ago that required another company to repairThe problem is explorer.exe will not run. Double-clicking a shortcut on the desktop, clicking the text name of a program from the Start menu, and even in the cmd results in the same response, a dialog box pops up stating windows explorer has stopped working.
windows is checking for a solution to the problem. followed by another box stating windows explorer is restarting. But the requested application never starts. I have run the Ultimate Boot CD 4 Win, replaced the hard drive and cloned all data, run numerous registry scans, malware scans and antivirus scans. Initially removing over 1500 virus/malware hits and over 1400 registry errors. But the main problem persists, explorer.exe won't open programs.

Looks like something is holding it up, I reinstalled the drivers but I think it might be a software issue where a program is not exiting properly and holding the system down.Every once in a while the system will shut down but most of the time it hangs on shut down, times out and errors out.

I have had this computer up and running with the same LEGIT copy of windows 7 64 bit ultimate since Christmas time this year. All of a sudden the other day it just started locking up all the time. It runs Ubuntu well that is installed on another hard drive. It also boots into safe mode fine. I ran antivirus and malware scans that turned up nothing. I then checked the hard drive for disk errors and it came back fine after multiple checks. I had went into msconfig and made it restart with a clean boot still the same thing. At this point I gave up and had backed up everything and reformatted the drive and reinstalled the same copy of Windows 7 and now have the same thing. I have done multiple hard drive checks, memory tests, I have taken out one of my graphics cards and made it not sli.

I have a dell XPS l{ess then 1 year old} quad core Intel processor plenty of memory and all. I am trying to upgrade to win 7. The compability manager says I am fine for the upgrade. During the installation the computer seems to be locked up about 3 quarters of the way through. The progress bar is simply stopped. I started the install about 11:00pm and it's now 5:25am. Should it take this long? This is the 2nd time I have tried this and the same thing has happened both times. The only way to abort it to restart the machine and then of course I will have lost all the vista files and updates.

I am running Windows 7 64 bit with the latest updates installed.
Today i switched on my computer, logged in and after a few seconds the computer locks up. I am unable to open Task Manager or any other program. I am still able to use the mouse, but nothing opens. I tried Safe Mode and it works fine. I am in safe mode as i am typing this.
In safe mode I am running a scan with Spybot Search and Destroy. It has found nothing.

I wiped it clean from issues of locking up. I have done 3 fresh installs of Windows 7 Ultimate 64 bit retail using all up to date drivers and everything, I have tried with CPU overclocked and normal clock. When I boot up she runs fine and then when I start listening to music off of my backup drive or browse the internet she will lock up at random, and by lock up I mean it is like im looking at a picture of my screen frozen with no responsiveness whatsoever not even the mouse moving no HDD activity ... nothing! So Ive installed the OS 3 TIMES fresh install new partitions format etc. It does it every time after I let windows update do its thing or just listen to music off the backup drive.pecs are:Windows 7 Ultimate x64 RetailBiostar A780XA2-03 Socket AM2+ MotherboardAMD Athlon 64 X2 3800 CPU4GB Ram - I have swapped sticks that I have had - ( 4 1gb sticks 533mhz)

For the last couple of nights, there has been an update to apply when I log off. In both cases, the update seemed to hang and I left the computer switched on overnight with the monitor switched off.On the first occasion it was still hung in the morning so I reset the computer. All seemed to be OK during the day but when I came to close down there was an update to apply. I guess it was the same one. It hung again and I left the computer overnight again. This time it had switched off but when I switched it on again it came up with a temporary profile.A message appeared telling me to look in the event viewer but that is a waste of time as there are several hundred million entries which don't mean anything to me.Where do I go from here? I guess I can do a system restore but that is likely to lead me back here after a day or two as the system tries to keep itself up to date.

I cant get my Windows 7 to start up. I'm not sure if this is my PCs problem or windows. It starts up, gives me the ASUS screen where I can go into setup (though messing around in it hasn't helped yet). otherwise it goes to black screen where I can choose start windows normally or launch troubleshoot. if I pick start normally the windows logo comes up, loads, tursn black, and resets the PC. If I choose troubleshoot, it goes black for several minutes, shows the Windows 7 BG, and just gets stuck there. I'm not sure what to try to get it to boot.

When using Windows 7, it randomly goes to the lock screen during an active session. This has been the case on multiple computers running Windows 7. Immediateness proceeding the lockout the screen flashes black and than shows the login screen. All of the external hardware is the same, one computer was a desktop, one is a laptop.

It is an HP Pavilion dm3 Entertainment PC running Windows 7 Home 64-Bit. The computer had several problems with it so I did a system restore that is built into a recovery partition. The install went fine, but then when it was loading in the 2nd time... it locked on Personalized Settings: Microsoft Windows Media Player. The problem I am having is that the laptop does not have a CD drive so I cannot put in a Windows 7 disc and run a chkdsk /r. I can log in to the machine if I go into safemode with networking.

I have this absolute annoying issue with my Windows 7 Home Premium. If I leave my computer on for roughly an hour I will go and attempt to either rename a file or search a file in the normal os search menu. The second I type one letter the os locks up and I am forced to end the explorer.exe process. I have recently reformatted my computer no more than 4 months ago and prior to that I was given the same problem. I heard and read in select online searches this has to do with shell extensions of some sort

I have been having this problem for about 2 weeks. I have tried disabling various services but have not had any luck narrowing it down. I have attached the Dump & System files. I am unable to create a System Health Report since it cannot be created in Safe Mode and my computer locks up before I can create it in normal windows.
My computer is a Toshiba Satellite L675D Laptop with Windows 7 Home Premium 64 bit w/ SP1 OEM. It's about 1.5 years old.

I've been using computers since Win 3.0, but have recently built my own computer for the first time. Generally, everything works great right up until the point it doesn't.Sometimes my PC will randomly just "lock up". The screen freezes, the keyboard is completely unresponsive (including ctrl-alt-del), the mouse cursor is the spinning circle. The only way out is to hit the RESET button.It seems fairly random, and has happened while I was using iTunes, Outlook, or other programs.The one constant is that every time it happens, I can see that the HDD activity light is *solid*. It's not flickering / blinking like with normal HDD access, just solid. I don't know whether there is something truly being accessed, or whether the solid light is just a red herring.
Also, I don't know if the system is actually frozen, or whether there's something hogging the system to the extent it's so slow that it appears frozen. It's a pretty beefy system, so whatever it is would have to be really doing a number. I've only ever waited like 2 minutes before giving up.Given that every time it happens the HDD light goes solid, I have to suspect it's something with the hard drive subsystem, but I don't know how to begin troubleshooting whether it's a mobo SATA port issue, an Intel RST driver issue, a hard drive issue, a cable issue, or maybe it's not the hard drive at all!Here's some details (see more in my Systems Spec)Recently purchased DZ68BC mobo Prior to Windows 7 installed, verified mobo BIOS default was AHCI Installed Windows 7 64-bit Home Premium Win 7 appears to use AHCI After installing Windows, ran Intel utility to update/install all drivers, including Rapid Storage Technology drivers (did *not* update mobo BIOS) I am NOT running any RAID.Again, everything seems to work really nicely, right up until the point it decides to instantly freeze It's hard to troubleshoot because it's so random, I don't know when to expect it, and after it happens I can't bring up any tools (i.e. Resource Manager) to see what's going on.

To start off here is my system:
CPU: I-7 930
RAM: 12GB
HDD: 500GB WD Blue
Power Supply: 750W Thermaltake
AMD Radeon HD5900
I can take pictures of my system later tonight.My issue is that when I boot my computer, sometimes Windows 7 will get start at the Win 7 glowing icon (startup screen). When it locks up there is no HDD activity. Occaisionally, after power cycling the desktop a couple of times it will get into the windows desktop. Sometimes I can do a few things but then it will lock up and either be really slow or it will lockup, then unlock, lockup, then unlock.When I boot into safe mode with networking everything seems okay and I don't experience any lockups. Now all of this never used to happen. I recently moved (for a job) and a company had packed up and shipped my desktop PC. They had packed it really well. But before the desktop was shipped everything seemed to work fine. When I unboxed it and setting it up in my new place is when it started behaving this way.

I am using an HP Pavillion DV9700 laptop
BIOS F.2C
AMD Turion 64x2 TL-60 2.00 GHz
2 GB on board
Windows 7 Home Premium, 32-bit OS, all updates installed
Somewhere, after a Windows 7 update many months ago, the problem started. I had no problems before. It started with the OS not recognizing the optical disk drive that came installed with the laptop. The computer's set-up BIOS recognizes the drive as being there. The optical drive does not show in Device Manager. I tried changing out the disk drive, it did not work. Soon, Windows 7 would occasionally lock up at the boot screen, but work fine on a cold reboot following a lock-up.
But then the lock-ups became permanent and cyclical. No amount of reboots would facilitate. I went to do a clean install using an external USB optical drive and accidentally discovered it cured the problem! The laptop will not lock up if the external USB optical drive is hooked up and turned on when starting the computer. I tried a clean install of the operating system. I tried updating the drivers. Windows 7 always recognizes I had problems booting and sends the error messages to Microsoft.

I built a new PC this past summer (specs are in my info). During the initial setup and installation of windows it locked up on me, but after a couple of tries, Windows 7 Ultimate x64 was properly installed. Since that point my computer locks up relatively frequently. When it locks up nothing responds...mouse and keyboard are useless, the last 16th of a second of sound is repeated, and the network itself actually locks up (no other computers on the network can access each other or the internet).The computer locks under the least demanding situations. I can play Skyrim for hours with the graphic settings set to max and it doesn't freeze. Meanwhile I play Dungeons of Dredmor or some fairly basic flash games, and within a half hour my computer will lock up.
I have run Memtest for 48 hours resulting in 0 errors. I have RMAed the processor & the motherboard. I have taken out one of the video cards and switched them. I have updated the bios. All of which have had no effect.Initially the CPU was running quite hot with the stock heatsink, but upon replacing it the CPU peaks at 50c.

I tried to google for software which locks WHOLE computer for period that I can decide before locking.Ideal program would be : I can make hotkey--and when I press hotkey computer will shutdown and I wont be able to use my computer for X time I configured.Basically I want to disable my computer fully with hotkey. And I wish there are'nt any way to bypass (at least easy) this lock.If someone knows program which is exactly what I described or something to that way
