Windows 7 Computer Freezing And Becomes Unresponsive
Feb 6, 2012
Recently my computer started freezing it completely freezes and becomes unresponsive and I have to hold down the power button to reboot, so my first attempt was to scan the hardware I ran a Pc-Check diagnostics and all the hardware passed I then completely formatted the hard drive and restored the computer. Once Windows 7 completely installed I installed the missing wireless driver however, after using the computer for about 15min it froze again. I then disassemble the laptop and did some internal cleaning I blew out the dust from the heat sink and applied new thermal paste to the processor. Even after that the problem still remains. Now there is a catch when I boot the computer in safe mode it doesn't freeze even after leaving it on for 5hrs so I don't know what the problem is in normal boot.
Specs:
Toshiba Laptop
Model L505-S5984
Windows 7 SP1 64-bit
WD 320 GB HDD
2X4GB DDR3 Memory = 8GB
Intel Core 2 Duo Processor T6500
Recently both my PC and Laptop have started to freeze intermittently when surfing the net. By freezing I mean that the computer becomes completely unresponsive with the screen stuck on whatever page I was on at the point of the freeze - the mouse cursor stops moving, the clock stops ticking, no response to control-alt-delete, etc. Nothing I can do but power down and re-boot. I have tried just leaving the PC for an hour but it does not recover.
This happens regularly but intermittently and at random intervals. I can rarely go 30 mins of surfing without a freeze. On my laptop the fan really ramps up when this freeze happens - as if the CPU usage has gone up to 100%. However, the on screen CPU gage gadget does not change as the whole screen is frozen. When I log back in there is nothing in the windows event logs for the time of the failure.
The PC is on Windows XP and the laptop is Windows 7. I use a mix of IE9 and Chrome on the laptop and IE8 and Chrome on the PC. The freeze happens using any of these browsers. The only thing that I can see that the PC and Laptop have in common is that they are using the same router (PC via cable and laptop via wi-fi) and I have Norton 360 and Norton Family installed on both. How I can track down the cause of this issue? (Disabling Norton Family makes no difference.) Any other logs or logging tools that I could use?
remove ZeroAccess trojans that were traumatizing my laptop erfectly (used ComboFix,MalwareBytes and TDSSKiller) and the malware doesn't show up on any scans anymore (ran from Safe Mode), but I cannot access my desktop for more than 5min at a time before it freezes up and I have to manually shut down and start up again. I managed to re-install my Kaspersky Internet Security 2013 temporarily, but it doesn't show up on my desktop or taskbar. I have tried SFC/scannow returned :"Windows Resource Protection found corrupt files but was unable to fix some of them." My system restore does not work either for some reason since I got this laptop a year ago and Startup Repair shows no errors.. I am relatively good with computer diagnosis, but this one has me losing sleep for two days straight.
My computer is very unresponsive with hangs which can last up to several minutes where nothing is clickable, the mouse is movable, I can hover over desktop icons and see the outline register, but when I click, for example to open my computer, it will start the freezing.Task manager does not open, saying with an error message:"Failure to display security and shut down options The logon process was unable to display security and logon options when ctrl alt delete was pressed. If the operating system does not respond, press ESC or restart the computer by using the power switch."I checked performance monitor and there is no noticeable hardware issue, which makes me believe it's either the PSU or motherboard. I took out the ram one by one and tested the system and the same thing happens.My most likely guess is that the power supply is failing, and this is just early symptoms of that. I already had a power supply fail on this computer 2 years ago, but at that time it would shut the computer down unexpectedly.I removed viruses, spyware, and did all the basics. This is a fresh system install.
When I first installed windows it started to work just fine but I soon noticed that it would randomly freeze every 15-30 minutes of use, but not on a particular program or anything. I assumed it was drivers so I installed the latest drivers for my GPU and MOBO and keyboard. It seemed fine again until it started crashing again. I ran a GPU burn test and a CPU burn test it passed both. (I tried runing memtest86+ but it froze at like 12%) Then I tried fixing the registry so I downloaded ccleaner and fixed the registry problems. Freezes continued. I finally decided to re install windows so I did and the problems still continued. I am at a loss of what to do and can't think of anything else.
i have a acer aspire am3802-u9062 and while playing games like sc2, world of warcraft, and multiple other games, the computer makes the humming sound through the speakers which i assume means its frozen but the monitor becomes unresposive. i've tried dusting out the inside, taking off the side, turning the back facing the open part of the room, putting a fan by the side of it, so it doesnt seem like a heat problem. i have the recent video card update. i can also watch live-streams and hd videos on Internet with ease and no freezing. im baffled and can't figure it out. also have never had a bsod.
os - windows 7 (home premium 64 bit) cpu - intel core 2 (quad proccesor q8300) memory - 8 gb ddr2 hdd - 1 tb odd - dvd super multi drive vga - nvidia geforce gt 220 1024 mb
it only started happening recently, about 3 weeks ago. i've also ran programs like advanced system care, smart defrag 2, fix cleaner, ccleaner, along with full virus scans?
im running a windows 7 computer with dual video cards to support three monitors as its a work computer, i have 4gb of ram and i have a few work programs on the computer, it was running fine but recently the computer has started to become really slow randomly and the mouse will skip all over the place instead of being a smooth movement. just wondering if you guys have heard of it before. it seems to be when i ask the computer to do something (eg open another program or change from one program to another.) wasnt always like this. also the physical memory use is over 50% even when most stuff is closed. Also it seems slow to boot. but i think this was just the amount of programs opening on boot. ive disabled a few.
i am currently unable to work on assignments on my own computer or enjoy games because it freezes completely sporadically requiring a hard boot. essentially the computer freezes on me and the keyboard becomes disabled and unresponsive. the mouse cursor on the screen slows down, like the sensitivity was turned down 95%, and moves sluggishly, and then i know the freeze is coming. the computer desktop freezes completely, the keyboard becomes disabled and sometimes the screen turns a faint transparent white depending on what application i am running. the cursor then turns into an animated hour glass that i can move around the screen totally normally, with no lag, but everything is unresponsive. i then need to do a hard boot and end up frusturated, tempted to through my computer at the wall.i've scanned the computer with at least 10 different reputable antivirus programs and i have repaired all the registry errors. i've uninstalled programs i no longer need and searched all over solutions, to no avail. [code] i looked at event viewer to try to see a log of the issue but the only error it reported was id 41, from the hard boot. when i'm on Internet and it locks up permanently, the Internet video continues to play.also the freezing is totally random and sometimes i can go for 5h without it happening, other times it freezes up within 10 minutes. usually it freezes up between 10-30 mins of system starting up.
it happens in different times, i can be on internet, while gaming or while letting my computer open and doing nothing on it,
it kind of crash, when i have my headset on my ear there is a noicy BRRRRRRR mouse + keyboard activities are not available, ( can't use them, my computer just froze like this. for no reason. havent installed anything special beside ( elder Scroll: Skyrim & Call of duty modern warfare3
it's been about a week now and my computer just freezes. and stays frozen. it happens most often when i leave a browser up and walk away from the computer. the only other thing i have noticed happening lately is that i have been getting warnings that my browser is using a lot of memory. it says this when i am running an app on facebook or when i have 2 or more tabs open like in Internet. i am not very familiar with the tools used with windows seven so i did not run high jack this. (i am using internet explorer 8)
My computer was working fine until I downloaded the windows service pack 1. First it was every now & then but soon my computer was freezing up ( not responding ) and it was impossible to even complete a document. This happens in all applications. I noticed with each new window update the worse my computer got. Still under warranty I spent hours on the phone with DELL twice, finally I did a fresh re-install of windows 7 professional. After the fresh install everything was fine. UNTIL I downloaded the windows updates, it started to 'not respond' again. I uninstalled the updates. The not responding issue is gone but I am concerned about windows security updates. Do I need them? I have contacted windows about this issue many times over the past several months with no response.
my computer started freezing on on the windows loading screen, so i had to turn my computer off again, wait a few seconds and start it agin, it then worked on the second time. i couldnt get into any kind of safemode.when i got into windows i had loads of generic win32 errors, i couldnt acess the internet or any anti spy/virus programs. i shut it down and it hangs so i have to manually swith it off.i was on xp so i thought i would format my computer and install windows 7. This has helped with all the win32 errors but my computer still freezes on start up at the windows loading screen and still requires me to swith it off and restart it, this works most of the time. might have to do this 2 or 3 times.i have looked in the events viewer and it says i have 3 errors: error 6 kernel process power / restart manager.
I have a 2 month old Lenovo with Windows 7 Home Premuim. When the Windows Splash screen comes up, the PC Freezes. After about an hour i can login with no issues, but the event viewer shows many errors. the error is:
windows event id 7001 The Computer Browser service depends on the Server service which failed to start because of the following error: The dependency service or group failed to start.
I can also boot into Safe Mode just fine immediately after the freeze.
I keep getting an message: Windows explorer has stopped working. It gives me the option to check online for a solution or restart the program. It doesnt matter what I pick, or if I click the esc button. It will keep popping up.
Here are the problem details:
Problem signature: Problem Event Name:BEX Application Name:explorer.exe Application Version:6.1.7601.17567
[code].....
I have done a full system scan with my anti virus and it has found nothing.
I have a new Toshiba Satellite, 2.3ghz core i5, 6 gigs of ram and a 750gig hd.When i open My Computer, the window freezes up, the green bar keeps scrolling infinately and no icons (like hard drives, disk drives) appear. Same goes for Control Panel.Also, when i close explorer.exe from task manager, i am unable to restart it.
I recently came home to my computer after a 7 month break. I had to update a lot of things like drivers, programs, etc which went very well and I believe that all of my drivers are up to date. The problem that is occurring is that occasionally my computer will freeze for about a second and then a robotic buzzing noise will play through my headphones. I am not really sure what to think of this and I've looked for quite awhile on Google. The main answer that keeps appearing is that I should clean my computer out because it may be dusty. The problem with this is that I have no idea how I would safely clean the inside of my computer.

I should also mention that my computer has Blue Screened once since I turned it back on a few days ago.
I got all the motherboard drivers and the video drivers installed then when i installed the drivers for my wireless network card and restarted and it froze on the starting windows screen.
I've been trying everything i can think of to fix this. I pulled the extra memory out, switched the power supply with one from another rig, switched the hard drive out for another one that i had.
after that, since it was a fresh build and nothing was saved on it i tried to reformat the hard drive and re-install windows, but the install disc also freezes on the starting windows screen.
so now i can't get it boot normally, in safe mode, from the disc or from another hard drive. when i try and boot in safe mode it stops at ClassPNP.sys
I have an old Toshiba Satellite L355-S7905 that was handed down to me back in 2009It gave me some problems beforehand (needed a new OS twice since I got it) but over the past year it's been fine. Suddenly, out of the blue, the OS crashed on me a few days ago.The crash was pretty bad and the OS wouldn't boot anymore. So, I did what any logical person would do; I reformatted my HDD (to ensure no viruses or spyware remained) and attempted to reinstall Win7 Ultimate. After the install, I manually updated all my drivers, and went underway resituating my programs. All was well with the universe, and then it happened.My system froze. One reboot later and it started freezing any time I tried to launch Firefox. Shortly after that, it started freezing whenever I tried launching any program at all. It even froze when I launched the Command Prompt. I've tried everything I can think of, but nothing seems to solve the problem of the CPU spiking then the system locking up. I've tried virus scans, registry cleaner, disk defragenation, and disk clean up
does anyone know what is wrong with my computer? can u please tell me if it is a virus or what can be the problem, and how to solve it if possible? alot of times whenever i use itunes or go to Internet on my computer, my computer freezes. my computer wont allow me to do alt control delete so i can end task the programs that r opened cause nothing pops up when i do it.about the freezing i hear the song play on Internet but my computer screen just starts becoming blurry and starts to glitch.i have tried to scan my computer with avira and malwarebytes anti-malware full scan and quick scan on both, but it does not detect anything.
My computer keeps freezing. Doesn't matter what I'm doing. HD is good swapped a new one same issue. Reloaded windows to no hope as well. Yet runs fine with linux systems. No BSOD/ black screen just locks up no activity at all ( on windows). Computer is only two years old.
My computer keeps randomly freezing up, I know when it happens because my mouse starts to skip, and then like 30 seconds later, my whole computer freezes?
the other two ( won't mention names ) did not reply in a week's time. my computer went nuts from one day to the next. Internet videos freeze but i hear the audio. i have "google" as my homepage but it keeps changing to babylon... i've removed it but it keeps coming back. also, i try typing anything and have to wait for cursor to catch up to what i'm typing... i get the following message every time i switch from one webpage to another..

i don't know much about computers, but i also can't download in safemode with the tool that was offered by this site so i'm not sure what all i should be includingi have an hp pavilion g7-1219wm notebook with windows 7. maybe about a month ago or a bit longer, the computer froze up while i was watching a movie on netflix. for a few days then, it'd been going slow and freezing momentarily but this time it would freeze for long periods of time and a few times i shut it off by holding down the power button (which i know you aren't supposed to do, stupid me) then when it wouldn't restart, at all.i did a recovery and re-installed most of what was in windows updates (except for two/three which refuse to install) but all of a sudden, it began freezing again. when i attempt to start normally, it seems fine - for under five minutes then everything freezes. i can move the mouse around but that's the only thing i can do. i've been using it fine in safe mode with networking thinking this month, we'd be able to get it fixed but that's not happening and to top it off, it's begun to freeze even in safe mode with networking
I have a samsung laptop, and run with Windows Seven. About a month ago my problem started. My computer will freeze and require me to manually shut it off and restart. At first it happened infrequently, but as of yesterday it freezes right after it starts up. I run spy-bot search and destroy, which I did using the guest profile. It found and fixed about 62 problems. I hoped that would have fixed the problem, but unfortunately it hasn't. Right now I am operating in safe mode.
So in the past week, my computer has started freezing. After about an hour of use, the screen will freeze. Sound will still play for a while and the mouse still moves. But other than that, it completely freezes.
Ctl+alt+del doesn't do anything and I have to manually shut it down.
Sometimes if it sits for a while and I don't mess with anything it will black screen and tell me to insert bootable media.
My computer is only about a year old and I put it together myself. I have an 64 GB SSD with Windows 7 intel i5 2500k 3.3ghz CPU 8 GB of RAM EVGA GTX 570
My graphics drivers are up to date. My registry seems in order. I have no virus' showing up under my scans. My PSU doesn't seem to be overheating. Memory test in my BIOS shows fine My case has plenty of airflow HD tune pro doesn't show any bad sectors And I've cleaned up with CCleaner
I have a Toshiba laptop. windows 7 home 64 bit. I uninstalled windows live mail from my computer & since then my computer is Verrrry slow. if I switch off my adsl the computer's speed is normal.All programs are "not Responsive" when i am connected to the internet..Please help. I ran a virus check (bitdefender ) no viruses were detetected.
I am having issues with my computer freezing. It's not frequent but it and it happens pretty much whenever it wants. I can be rendering a video in Premiere Pro CS5.5 or just downloading something with the system completely idle. I check the Windows Event Logs after every time I reset the machine and there's no errors at the time of the crash. At the time the computer rebooted it says the last system shutdown was unexpected.I ran Memtest86+ 4.2.0 and it came up with no errors. I also ran 3DMark Vantage, I know it's not really a stability test but I wanted to see if it would cause it to freeze, which it didn't. But then I ran Prime95 on a stress test and it causes the machine to freeze after the 640K Self-Test passes everytime I run it.
