Windows 7 Ultimate X64 - Random System Freezes

Nov 27, 2012

A month ago I started experiencing random system freezes (system halts for ~30sec and then resumes to work normally). I thought it was my Windows 7 going insane, so I did a clean install, but the problem is still present. I read somewhere that SP1 might be the cause, so I haven't done an update to SP1 this time - but the problem remains.

Display Freezes / BSODs And Random System Crashes

Oct 27, 2011

My computer has been crashing a lot lately. Usually, the computer freezes and weird lines appear on the display when it happens. Other times it just shows a BSOD and restarts. It started happening around 2-3 weeks after my motherboard, processor and RAM were changed because a part of the previous motherboard had burnt. The previous motherboard was ASUS M3A78-EM, the onboard graphics was ATI Radeon HD 3200 and RAM was 2 GB DDR2.I took the PC to a my computer vendor after everything I tried had failed. Firstly, he diagnosed it as an issue because of improper earthing/grounding in the switchboard where I plugged the computer and the UPS. I got the earthing issue sorted but to no avail, it still hanged/freezed. The second time I took it to him he said that he might have to update the BIOS and when I brought it back the problem had apparently been fixed but that was only for a few days. After like 4-5 days it started happening again. Same weird lines - green, magenta, purple and all the rest of it - started appearing. The HDD LED stops when this happens. I only observed the LED today, though. Today the computer freezed without those weird lines on two out of the 5 or 6 times it happenrd, it looked like it had just hanged but the HDD LED had gone off.Sometimes the PC doesn't start up at all immediately after it has crashed. That's what led me to guess it's a hardware issue. Also, it happens in safe mode and Windows XP too (I dual boot Windows XP and Windows 7) and I remember it once happening even before the computer had completely booted.Computer details:Windows 7 32-bitASUS M4A78LT-M-LEAMD Athlon II X2 250ATI Radeon 3000 onboard graphics1 x 2 GB DDR3 RAM250 GB SATAMinidumps and NirSoft BlueScreenView HTML report: url..

Random Freezes / System Lock Ups When Playing Games Or Watching Videos?

May 3, 2012

The problem is that I will get a system lock up, or freeze when playing games like Portal 2 or FM2012. The freezes are very random however they occur the most when trying to play Co-op in Portal 2 (say about 80% of the time when trying to play it). However with the likes of FM2012 or other games, I can literally play for hours on end without a crash, but other times a crash could happen within about 5 mins.I also seem to randomly crash if I watch a HD video in full screen (1920x1080) however I cannot recall such a problem watching it minimized (using VLC). I also used to get random crashes while browsing the internet on certain websites, however I haven't had this issue since upgrading my RAM.

When the PC does crash, the monitor will just black out and if sound was playing at the time it will usually loop or repeat. The only thing I can do is a hard reboot and upon restarting the PC it will say about the unexpected shut down and to start windows normally however I don't seem to get any minidumps. I've had this problem now for quite awhile, and at first it was something I just overlooked as a random occurance but now its starting to drive me crazy! My system specs are as follows:[CODE]

Random Freezes, Sometimes Glitchy Freezes And Rarely BSOD

Nov 28, 2012

i have random freezes sometimes they are glitchy and rarely bsod all on bootup or up to about half hour in (which also turns of the mouse). also Internet doesn't autoplay playlists and all sugestions next to the video are black. this started a few weeks to a month ago, first it seemed just a minor annoyance but it started to become more often the last few days. i've tried some checks but without success.
also i remember the week before those crashes that twice the screen driver crashed for a second or 2 and then a message popped up about how a monitor driver crash was adjusted, always when i played a certain game that is still in beta so i taught it was the game.

Random Freezes On Windows 7?

Jun 13, 2012

I'm searching the web, listening to music, or playing some games on my computer, at some point when I click on my desktop it will give me the waiting mouse cursor. Then I cannot click into the start button on the bottom left and the only way to restart the computer is to force shut it down.

My set up is a windows 7 64 bit computer with mbam and bitdefender protection. I have on my desktop a gpu meter and the weather from windows gadget if that makes a difference. My specs are: ATI Radeon 6500, 720 psu, 3.2ghz six core computer, 12 gb ram.

Windows 7 Random Freezes

Jun 15, 2012

I'm using Windows 7 SP1 on a quite capable machine. I'm getting random freezes, and what I mean by that is programs just freeze and wont respond. Games , Opera and Skype freeze for sure but the task manager manage to stay awake for long enough for me to do a basic overview of the problem. CPU usage of all programs drop to 0 but the memory usage slightly increased. The Network usage dropped to 0 while some of the cores of the CPU were being used a little. That is all I know. The freezes take about 30 seconds to 1 minute and appear at random moments and Screw me up really good.

Random Freezes In Windows 7

Jun 17, 2012

I just wanted to see if I could get an opinion concerning random freezes in Windows 7 (on an internal Seagate Momentus XT hard disk drive). I have Windows 8 installed on an external drive connected to my computer via eSATA and it works just fine; no freezes have been reported. What happens is that after periods of non-use (15 minutes or more) and even longer periods of use (over an hour) my computer freezes. Instead of my pointer cursor I see the all-too-familiar blue wheel indicating that a process is working, but it never finishes whatever it is doing.

Windows 7 - Random Freezes?

Jul 9, 2012

for the past 5 months i've been experiencing my windows 7 to randomly freeze at least once a day. it will become unresponsive, the waiting icon (the little circle) will replace the mouse pointer and the only way out will be hard restart. initially i thought it was either corrupted windows files or damaged hdd. last week i bought myself a new hdd - 120gb ssd drive. i made a clean install on the ssd drive and i formatted my old hdd to use as storage. after few hours of using my newly installed windows copy i experience the same problem.it seems to happen a lot when uploading - for example it happens every time i try to upload a Internet video. but not just that, sometimes it will randomly freeze upon launching chrome etc.

Windows 7 Freezes At Random, Hardware?

Jan 6, 2012

he's had a custom built PC for a couple of years, upgraded to Windows 7 from XP last summer, just recently it began freezing, about every other day.The freeze is complete. There's no getting to Task Manager, no moving the mouse, just a frozen screen requiring a hard boot.There's no pattern. It could be while he's using the internet, it could be while its idling, it could be in sleep mode.I've disabled sleep and screen saver and it still freezes up.I've run a lot of malware/virus programs and they don't find anything.

Random Windows 7 Freezes After Ubuntu 10.10 Install

Oct 16, 2010

I currently have Windows 7 Ultimate 64 running on my Asus laptop. I decided to install Ubuntu 10.10 along side Windows, as I will need it for work. It was installed via side-by-side and re-sized the partition

The installation of Ubuntu was flawless and works great, but now when I boot to Windows, its will randomly freeze, sometimes in 1 minute, sometimes within 10 minutes.

The only way I can solve this issue, is to either perform a disk scan from windows or restore the MBR.

The disk scan works, and Windows run fine, although If I boot Ubuntu again, run that for awhile, then boot windows again the problem returns.

Restoring the MBR works as well, though without a dualboot, its useless I have also tried EasyBCD and replaced GRUB with Windows boot manager, though same problems.

Windows 7 / XP Freezes At Random Points During Installation

Jan 30, 2012

So I just received some new computer parts today:
AMD Phenom II x4 960t
8gb patriot pc3 10666 ram
ASUS M5A78L-M LX motherboard

I've installed the new parts but am having a lot of difficulty installing windows. I've tried installing both windows 7 and winxp multiple times with no luck. Both of the CDs have worked in the past, and there aren't any visible scratches or damage to them. Win7 and xp freeze at random points during the installation, usually during the "completing installation" or unpacking files stage.

I've tried the installation with two different DVD drives, with only one ram stick, various bios settings, etc. One thing that I've also noticed is that it will fail to boot unless being powered off completely. For example, after the initial stage of copying/unpacking files the usual reset that windows does to continue with the installation results in only a black screen (no beep).

However, when I power down the computer completely then start it up, the installation Is able to continue but only to eventually freeze. One install did actually work, however after installing a few drivers it started freezing while windows was starting up. It would start in safe mode and I did a system restore but it continued to freeze. I figured at that point I had nothing to lose and began trying another reinstall - and now it won't work at all.

On a random basis Windows 7 freezes for about 2 minutes, then proceeds with the activities in normal fashion. The operating system and software is on a Solid State Drive while everything else is on a hard drive.

Random Freezes

Mar 31, 2009

I've just downloaded and installed Windows 7 7068 (32-bit) on my main PC and I've been having a pretty major issue. I start up and after a few minutes the computer will just freeze. I can leave it at the desktop for 10 minutes or play a game for 5 minutes, whatever I do, after a random period of time it'll just stop.

The download/cd is fine as I've got it on my laptop running fine...

There are no viruses as I've checked everything with different computers and scanners...

I've downloaded as many drivers as I can find that are for Windows 7, the ones that weren't I got Windows Vista drivers...

Oh, to elaborate, I've searched and nothing here helps, I can install fresh with all defaults and it'll freeze... I can install fresh with new drivers, it'll freeze... I can install fresh and load up games and applications, it'll freeze. In addition, safe mode freezes! And all other operating systems work, I haven't had any problems with previous builds of Windows 7 and Vista/XP still works fine, there's just something about 7068...

Anyone got any ideas?

RC 7100 64-bit - Random Freezes

May 18, 2009

I'm getting random freezes that require me to restart my computer and I'm not sure what's wrong. The OS installed fine with no missing drivers (aside from my wireless network card and my LAN drivers which still doesn't work: Realtek RTL8168B). At first I thought I had bad video drivers as I've experienced this before with Vista but the problem persisted even after updating to the lastest Windows 7 beta drivers from ATI.

It's strange because the system rarely froze during normal usage but the OS freezes immediately when I play any internet based games (Left4dead + COD4) or use any 3rd party program that requires bandwidth (utorrent + IRC).

I suspect the culprit now to be the wireless drivers but what doesn't make any sense is that I've had no issue at all with web browsing. Internet surfing and IM-based programs (Digsby) work fine. The wireless drivers work as expected.

Other things I've done:

Vista32 Home = stable.

Memtest86+ passed without errors.

All drivers current (Windows 7 betas if possible if not Vista64).

Ran programs that caused immediate freezing in compatibility mode (Vista SP1).

Power Options: Display off @ 30 minutes; Sleep @ 2 hours.

Turned off Media Player Network Sharing services (read it could be an issue)

Random Freezes In 7229

Jun 20, 2009

Ok so, I'm running build 7229 which appears to work fine doing any task but it will freeze indefinately at what appears to be random times, sometimes straight after booting up sometimes 2-3 hours of general use, there is no obvious cause for this as like it said it freezes at random times when I can either be doing nothing or merely browsing using firefox or using media player, I haven't really done anything intensive on it either.

What things would you recommend I be doing to try and solve this?

Also the install took a very long time as it hung at various stages of the process but obviously completed in the end, which happened with both 7100 and 7229, is there any specific reason for this?

Random Restarts And Freezes

Sep 24, 2009

I've been having this problem for a little while now and have had a hard time pin-pointing the source.

It seems to be caused by the network card I have (look in my specs). Whenever I stream videos using ORB the computer will reset what seems to be about every 10 minutes. When I stop streaming, it stays on. Sometimes I'll leave it idle for about 6 - 8 hours, get home and notice that the mouse isn't on and the machine is just locked up. The only way to recover is to reboot.

This did this with previous releases of 7 but I thought it would be fixed in the RTM. I have the most recent drivers for my NIC.

Random Win 7 X64 Crashes And Freezes

Oct 24, 2009

every time i try to install windows 7 on my new build, i do a clean install, however it spends about a second on the copying files part, then waits a few minutes before it starts expanding files. it hangs at 0% for a few more minutes then it will start accelerating. it will crash at random points while it is "expanding files".

the crashes vary, sometimes the display will explode and look lagged out then look like small tiles, the display sometimes turns red where shadows are as well, it also likes to just freeze. it frequently likes to freeze at 76 or 46%.

i had 7 installed one time when i kept my mouse moving constantly throughout the installation, but then the freezes would happen when i would boot into normal windows, but not safe mode.

Random Freezes - Solution

Dec 1, 2009

This is basically rehashing my post from this thread: Windows 7 freezes

I've been experiencing the same freezes a lot of you guys have been experiencing lately. The machine would simply freeze, mouse wouldn't move, keyboard wouldn't respond, and the only way out is a hard reset.

Then they got worse, and started happening within a minute or two of startup, very consistently.

However, Safe Mode still runs fine, so I figured something that's disabled in Safe Mode is the cause of the freezes.

At least for my machine, this assumption turned out to be correct, and I was able to fix the problem.

Here's my solution:

Step 1: boot into safe mode (if your system didn't just crash, do this by pressing F8 at the windows boot menu).

Step 2: click Start, type msconfig, disable EVERYTHING in both the start up and services tabs. Now reboot into normal mode and see if you still experience freezes. If you do, then this solution will not help you. If, however, the freezes stop, then you've just isolated the cause of the freezes to one of the services of startup items you disabled.

Step 3: run msconfig again (you can do this in normal mode, no need to reboot again), and enable all the startup items first. Now reboot and see if your machine starts freezing again.

Step 3.1: Freezing: if the system does freeze, then the cause is one of those start up processes now enabled. To find out which, disable the second half of the list (if your machine freezes immediately after start up, do this in safe mode), and reboot to normal mode to see if it still freezes. If it does, then the cause is in the list of enabled processes, and if it doesn't, the cause is in the list of disabled processes, so enable/disable a half of the appropriate part of the list, and try again.

Repeat this until you isolate the process that's causing the freezing, and remove the software related to it.

Step 3.2: No Freezing: This means your freezing problem is caused by a system service. Leave the start up processes enabled and continue to step 4.

Step 4: in msconfig go to the services tab, and sort the services alphabetically. Disable the lower half of the list and reboot.

Step 5.1: Freezing after reboot: the freezing is caused by one of the enabled services, so again, sort the list alphabetically and disable half of the enabled services and reboot. Repeat this step, minimizing the list of potential causes until you isolate the faulty service.

Step 5.2: no freezing after reboot: freezing must be caused by one of the disabled processes, so disable the enabled ones, and repeat step 5.1 for the second half of the services list, until you isolate the faulty service.

Step 6: verification: to verify that the faulty service is indeed the cause of your freezes, disable all other services and start up items and reboot your machine with only the faulty service enabled. If it still freezes, congratulations, you've just found the root of your problem.

If it doesn't freeze, then the problem is more complex and probably involves dependencies and concurrent services, and you'd have to use more complex methods to find out what exactly is causing this.

Step 7: fixing the faulty service: This is tricky, as these are all system files.

the first thing you have to do is figure out what files the service runs off of. In my case the service in question was Workstation and it was wksvcc.dll that needed replacing to fix my machine's freezing problem. I stumbled upon the service's .dll file name after many hours searching for a way to fix a corrupt service, so I can't offer any insights into how you might find the correct .dll file for your faulty service.

Now, to fix the service:

After you've tracked down the correct .dll file, locate it in windows explorer, change it's permissions so you can modify the file (do this by opening the properties of the file, and in the security tab's advanced page, first change ownership to yourself, then give yourself permissions to modify the file). Once this is done, you can rename the file to <filename>_CORRUPT.dll. Now, as far as your system is concerned, the file is MIA and the only fix is replacing it with a copy from the repository.

Click Start, type in cmd and right click the icon to run it as Administrator.

In the command prompt window, type sfc /scannow

This will run a system file scan and discover the missing/corrupted file, and then repair it by getting a clean copy from the repository.

Once this is done, go back to Start, type and run services, then find the faulty process and enable it. Restart your machine and see if this fixed your problem.

Hopefully someone can chirp in and include a link to to some comprehensive listing of Windows services and their respective .dll files, as I haven't been able to find such a list so far.

Edit: link to a list of services and their descriptions, thanks to kitesurfa: http://www.blackviper.com/Windows_7/service411.htm#A:

Once you go into a service's page, scroll down to see the .dll files listed in the registry settings (see attached picture for example).

The above solution worked for me, however, since it involves modifying system permissions and files, do this at your own risk.
