OS Will Lock Up - Screen Goes Black And System Reboots?
Dec 7, 2013
I am running Windows 8.1 and have been experiencing an issue as of late, without any hardware or software changes. About every 4 hours, the OS will lock up, start stuttering any audio, and then the screen goes black and it reboots. This has happened while playing a game, watching Netflix, just browsing the web, seems about anything (oncej ust launching Google Chrome).
I have checked the event logs and don't see anything (only thing is the Critical under system and it says your system did not shut down properly, no errors before it).

See title. How can I prevent this from happening? If I want to lock my device, I have to press the power button. When I press it again, the whole system reboots. This didn't happen in 8.

My computer randomly shutdowns when I use it for a while maybe 2hrs or 3, reboots by itselfs and windows cannot boot back, getting a black screen and nothing happens, So i manually turn it off and turn it on again to make it work. Sometimes it doesn't even want to work, black screen after multiple reboots So i need to syster restore it, sometimes that also doesn't work and i need to reset it completely.
At first i thought it was the new drivers i installed for my nvidea geforce gt640, the 331 version. I heard it was making pcs crash like mine does, so i downgraded the driver to 306 and it works for longer but the crash happened once again after a while, and after a windows 8 reset (deleted everything and reinstalled by itself). So this is a fresh Windows 8 i believe but still does crash.
After the crash that happened tonight, i restarted my pc and realised one of my fan in my pc is going extremely fast at random times but not for long. I went closer to hear which one was doing that and it seems to be the fan on my video card, I also touched my card and its very HOTTTTTT close to burning my hand ".".
My pc has been cleaned yesterday by my step dad, had lots of dust, even in the video cards fan, but now is clean and still overheating. Using a 350W PS which i heard is not really good and that i should upgrade really soon.
CPU Temp is fine, all fans are working properly, I believe my video card is broken or my PS not giving it enough power or something?
The auto reboots are annoying, making me have to restore every time and sometimes reset Windows 8. It seems to only happen when i do lots of stuff at once like mixing via audacity and having x2 perfect world clients up, plus radio streaming live.

I upgraded from Windows 7 to Windows 8 Pro. Everytime or almost everytime I click on an app or go to the desktop and try to get on IE 10 (desktop version), my screen flashes and goes black for a few seconds then returns me to the screen with the space needle, then I click on it and it signs me back in. When I try to use Google Chrome, the websites freeze up on me. I don't want to have to reinstall/reformat as I paid $40 for this for one, and secondly, I don't want to have to repurchase Office 2010 as my licenses ran out. I ran every update that comes up and restart, but this doesn't change this issue. . why it does this and any way to fix it without reformatting?

I am running Windows 8.1 Pro on a Desktop PC.
My issue is this:
My PC is on 24/7 previously on every version of Windows when I walk away, the screen turns off after 30mins of inactivity, the PC stays on and when I return, I simply moved the mouse and within 2 - 3 seconds the monitor was back on, and I was where I left it.
On Windows 8.1 that sometimes happens, but 90% of the time what is happening, when I return to my PC, I move the mouse and nothing happens, anything I press on keyboard etc, monitor stays off on black screen, if I turn the monitor off by the button and back on, it just stays black, the only way I can get back to my Desktop is to restart the PC!!
I changed several power settings around, disabled password on idle setting, googled many things and tried and its still doing it. The PC is still on fans etc, but doesn't respond.
Weird thing is, it did it today when I was watching a movie on my PC connected media server downstairs (app is PS3 Media Server used with a WDTV Live Hub) I came to use the PC and it was black screen, I went back downstairs and could still access all my files on the media server, so the PC is still up and fully running when it does this, but I just can't get the monitor to display anything other than black screen, again on a reboot everything is fine again.
To summarise, I have power setting to turn off display after 30mins, usually a nudge of the mouse brings the monitor to life, this is not happening, I can only get back to desktop via hard PC reboot.

Wife's computer upon reboot went into System Repair mode and said it might take more than an hour to complete. Now its hanging endless on a black screen. WIN 8 only 3 month only Sony VAIO machine.
If the laptop is powered off and is completely shut down and restarted...it is only going to a black screen. Nothing else?

I have a hp envy running Windows 8.1. I recently ran a system restore, and ever since it has run the hp logo, then gone to a black screen and stayed there. Things I've tried:
Boot in safe mode: No change. Startup Repair: Said it couldn't fix it, but I can't get to the log file to find out why (is there a way to access windows explorer from then startup repair menu? Maybe using the command prompt?) System repair:Said there wasn't enough hard drive space. Another system restore: Didn't work, blamed my antivirus. (McAfee) Full system reset: Said there was a drive partition missing.
What I could try to resolve any of these? I have access to everything in the startup repair menu(f11), as well as the BIOS, but I'm not really sure where to go from there.

My laptop is a
Sony Vaio - Model: SVE141R11L
Product name: SVE14135CXB
Pre-loaded with Windows 8 x64
Intel(R) Core i5-3230M CPU @ 2.60GHz
6GB RAM w/ 900GB HDD space
Purchased in Navy Exchange last year (around July 2013)
I have dropped it once or twice from at most a 3ft fall inside a padded case. I mostly use my computer for school work, some gaming, extensive video/photo editing, internet browsing. I've installed some debatable programs but have been installed long ago. Most of my programs included Microsoft Office, Adobe suite, Steam, iTunes, uTorrent, McAfee VirusScan Enterprise, Winrar, VLC, etc. But are now gone due to the refresh I had just done last week for prior problems, but still experience problems.
I recently been having issues with my computer where it just won't respond at all. Like today, I had it working for a few hours, but then went out and left my laptop on the lock screen, and came back to it being completely stuck. Completely stuck as in, no keys or clicks would unlock the screen to the login prompt. However, my cursor was fully able to move around the screen, and my caps/num lock buttons work as they display the lights enabling/disabling them. The time when it was stuck was 8:03pm, but the clock was stuck on 7:55. But on the bottom of the front of the laptop, the HDD orange light is not lit up at all, which I believe suggest that the HDD is not reading/properly reading. Oddly enough, when I unplugged the power cord, the HDD light flickered a little then disappeared, still no response - could be related to the PSU I suppose?
Another problem I faced before was the Windows 8.1 update failure, resulting in reverted changes, etc. I also had problems in the first few months of owning this, but found it was the incompatibility of an old antivirus that I guess didn't work too well with Windows 8 causing me to have to do a full wipe before. That was long ago. Moreover, the problems I have been experiencing have been unresponsiveness, from what I believe, are the fast boot Win 8 provides (but I turned that off), issues with Windows 8 not being able to load drivers from sleep mode upon opening the laptop (turned off automatic sleep), and now with the lock screen being stuck. I know my problems aren't detailed, but maybe these problems are linked to a bigger similar problem that people have been facing? My last bet would be to do a full factory restore/ repair, although I don't have a Windows 8 boot CD.

The following is the best way I can describe whats wrong with my system.
1) Boots up normally, use laptop normally for work, play, nothing is wrong at all
2) Put it to sleep either by power button, right-clicking windows button OR closing lid, and yes, it is Sleep
3) Laptop seems to go to 'sleep' state - the fan sound disappears quite quickly (5 seconds), and the power LED blinks - I've had laptops before and this is very very normal 'sleep' activity so i don't think anything is wrong here
4) 'Wake' laptop by either power button, or opening lid:
- power LED stops blinking and becomes a constant 'on', processor LED starts blinking like normal - at this point it looks like a normal wake
- after about 1-2 seconds, system POWERS DOWN, yes powers down - no sound, hard drive stops, no lights, for about 0.5 seconds
- system boots up again, taking the normal amount of time to power up, from fresh, ie, as if I have just shut down the computer, and started it up again.
5) enter Boot screen
6) sign in to Windows, and all my previous programs, windows, work, will be gone, but otherwise everything will work properly, just like if you started from a fresh boot up
When going to sleep, system will not 'sleep' but just go into a black screen with the power LED 'on' and no processor LED or any other light, fan still moves tho, and there is no way to fix it other than force restart. Fixed by installing latest Intel drivers for GPU
Tested solutions - disabling 'hybrid sleep', saying never hibernate, definitely checked that 'lid' and 'power button' actions are for sleep (not hibernate or anything else), cmd prompt > powercfg -h off, reinstalling all my display drivers to older versions, Windows troubleshooter (selecting power)

I've upgraded to Windows 8 RTM this weekend and I'm having this problem: Every time I boot the PC (shutdown or restart), the Num Lock key is off. Since my password uses numbers, and I'm pretty used to type it with Num Lock, I'd like to keep it always on. It was fine on Windows 7. Now, I've searched for it, and there is the "InitialKeyboardIndicators" key on regedit. I have changed values for all of them to "2", and it didn't work. My BIOS say to keep it always on.

Every time I Restart my Laptop, the Lock Screen does not show the Welcome Screen and skips directly to the User Account login screen. Actually, it shows a darkish blue screen for a couple of seconds and then jumps to the user account login.
When I use the logout function or the shutdown (and I power it back on) everything works normally.
I have ran SFC / Scannow in windows (8.1 by the way).

This morning I woke up to find that I could not log in to my windows 8 computer. The first 'lockscreen' would appear, but the when I clicked to go to the next screen to log in, all I see is text in the bottom right hand corner telling me about windows updates that will automatically update in two days (I have already installed most of the newest WUs).... Having issues with the latest WU?

"Performance power management features on processor 3 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
I've had 180 of these since February! I've tried tonnes of malware cleaning / fixing, driver updates, and sfc fixes, but still getting these usually when gaming.
I've attached a zip of SF Diags folder.

I have recently bought a new system running Windows 8.1 64 bit.
After I played Cities in Motion 2 on Steam the problem first occurred. The screen freezes and one or two seconds late the system restarts. There is no BSOD.
Yesterday I played all day with no issues but today the problem happens regularly, even when just browsing the internet in one window.
Find attached the SF Debug tool zip file.
The system is still under warranty but I thought I would try here first before going back to they system builder.

bought a new pc with windows 8 this week. set it up yesterday all worked fine, was on it again today - i uninstalled the crappy free trial anti-virus software that came with the computer and turned on windows defender. i was prompted to update software which i did. i turned the computer off and came back to it later.
when i turn the computer on now, it gets stuck at the lock screen. the mouse and keyboard do not work. the light is initially on the keyboard for a split second when first turn the computer on, then it goes away. the mouse is lit up but does not move. i have tried adding a second keyboard, or replacing the keyboard completely. also tried using a different mouse, it still gets stuck at the lock screen.
i have also tried pressing F8 when computer is booting up but it does not register it. i have tried to put in the windows 8 recovery CD - but this does not load.
i have obviously tried to reboot the computer several times etc.

I can't seem to find any way to lock my start screen once I get my apps organized and just the way I want them. Is there no way to lock your apps so that they can't be rearranged by someone? If not then that seems like a glaring omission. I spend a great deal of time arranging it and then my three year old comes along and messes it all up. I would like to prevent this. I know I can create a user password and just not let any use on it.

I recently installed Office 2007 onto my Vaio. It said it was successful and needed a reboot, so I rebooted. Upon reboot, it simply won't let me get to the lock screen (where I enter my pass/PIN). I have control of the keyboard (I think) because I can still adjust the brightness. The track-pad won't register my click to get into the lock-screen.
I tried to get into safe mode, which I've read is done by holding Shift and pressing F8 repeatedly at bootup. No go on safe mode.
Is there some alternative way to get into safe mode or somehow get into the lock screen?

Since upgrading to 8.1 I have started going directly to the Start Screen from the Lock Screen. Before in Windows 8, I went to Desktop. I have my taskbar at the bottom of Desktop which contains all the icons I want to access and it means now I am going back to Desktop from the Start. How can I organize my laptop that I don't directly to Start Screen from Lock Screen but go to Desktop?

Is there a way to change the default lock screen settings so that it displays on all monitors? For example, I have a triple monitor setup. When I hit Win + L, the lock screen only shows on the middle screen... I'd love for it to show on all three screens if possible.

I have a laptop with 8.0 pre-installed.Could normally access the lock screen with WinKey-L.
Since update to 8.1, this is no longer possible.(all other keyboard shortcuts that I've tried, works OK)
Account is local with admin rights; pwd protected; not MS-account. No other accounts.When I start the laptop, I have the Lock Screen to enter pwd.
I can get to the settings page to customise the Lock Screen, but not back to the Lock Screen!
Why can I not get to the Lock Screen with WinKey-L? (what settings are preventing this?)
