Random Freezes - Memtest No Errors
Jul 29, 2009
I have a laptop Acer Aspire 7720G, with Win 7 RTM installed from original ISO ( by zuko.. ) to try it before purchase..but it randomly freezes for 30-40 secs : (
Mouse can move, keyboard works but if I try to open folders or other, they don't
I thought it could be a RAM problem, so I run a memtest.. but no errors..
Now dunno what to do xD I've reinstalled 2 times but there are always freezes..what can be the problem? maybe a bad ISO? or a bad burn?

I have been getting what appears to be random BSOD. However, most times it has been whilst using IE Explorer (ver 8.0 ). I have an Asus G53SW Win 7 64bit 16Gb RAM. All updates have been installed and I believe all drivers are latest version. About 3 weeks ago the HDD had bad sectors and I had it replaced. I had a Crucial M4 128Gb SSD installed and an additional 8Gb of memory. I have run memtest (8 passes) and there were no errors. I have run HD Pro and there are no errors on the HDD. Attached herewith dump files and event logs. I have also attached a sys info file.

I have been getting BSODs for awhile now unfortunately. At first I thought it was my power supply not supplying enough power anymore because it's 2+ years old and has been through many builds.Well, I ran Memtest last night just to be sure, and after waking up 8 hours later, Memtest had reported over 450+ errors, this was with BOTH ram sticks inserted / being tested.My timings were set as they should be (9-9-9-24-2t command rate and 1.5v DRAM voltage).I'm currently testing 1 stick at a time to see if the errors pop up on one stick only. Now, in the BIOS, I have the timings set to 9-9-9-24-2t command rate, 1.5v DRAM voltage, but in Memtest it says: CAS: 6-6-6-20 / Single Channel (when testing one stick only)

I can no longer leave my pc on overnight or it freezes. If I run more than 2-3 programs it freezes. I was watching a video once with headphones on and heard a loud noise then freeze.I at first thought it was just one of my hard drives dying because I had similar symptoms before I removed it. But, the fact that the crashes are happening more frequently without accessing the questionable e: has me stumped.Then I figured maybe it was the overclock I did in my bios. But, restoring it to normal has had little effect on the performance of my machine.I have run and run on an almost daily basis the following: All updated daily or when available.

Superantispyware

CCleaner

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.

My computer has had problems starting up. On some occasions, I will get to the Welcome screen, and it will just sit there as long as I keep the computer on. Sometimes, it will get past the Welcome screen only to get to a black screen with no desktop or toolbar. To get it to work, I have to start the computer in safe mode and then restart it. I thought it was a virus, so I did a scan with my antivirus (Avast) but it did not detect anything.

my windows 7 system I use for music production randomly freezes. I was looking in the Computer Management Event Viewer and there are ALOT of MOUCLASS error references and also some windows update failures. Could this be causing the random freezes? Also, the system freezes on boot up and I have to reboot then it works fine for a while, but freezes again intermittently. I dont connect this system to the internet except for windows updates and DAW updates.

This is a new pc build using various parts we have accumulated. When using Internet Explorer I get app crashes. I have been playing DC Universe Online and get random app crash, display drivers stop responding, apphangB1, I also lose monitor signal. Here is a list of fixes we have tried already:
-We have disabled internet explorer add ons and even tried disabling IE completely, to no avail
-We have swapped out the 5770 for an 8800 GTX that we know works, same problem
-We have the latest BIOS/drivers
-We have run SpeedFan, CPU temp 41C
-We have run Memtest for both sticks of RAM at the same time in slots 1 and 3 and there was an error, so we tried to isolate the bad RAM by testing invidivual sticks in slot 3 - no errors on either stick? therefore, we put the sticks in slots 3 and 4, assuming there may be a problem with slot 1 - worked ok for a couple of hours, then game crashes and black screen with sound requiring reboot. Monitor is fine, as it works on my BF's pc with no problems.
-We have tried a couple of installs of Windows 7
-We have run chkdsk - no errors.The BIOS is running on default, nothing overclocked - we have used the correct timings for the RAM and autotimed them, same problem
We are currently not using an antivirus because we did not want to add more problems, but we will get AVAST.My BF has given up now, as there is nothing else he can think of to try. I feel we are so close to resolving the issue, as it did run fine for a while, but then a bunch of errors all at once. If it helps, here is a copy of the error log.

I bought a Sony Vaio VPCZ227GG almost 2 months back and its been running perfectly until the last week. There have been no hardware updates, system installs etc. only the recommended Sony Vaio Care driver updates.I will be using the laptop for a while and then it will just crash. The laptop stays on the screen it was on before the crash but the mouse, keyboard, basically everything is dead. The only way to cycle it is to power down.

Windows 7-64 bit Came preinstalled
Intel� Core� i7-2640M Processor 2.80 GHz with Turbo Boost up
8GB Ram

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?

I am trying to diagnose a problem with my machine, and in so doing I have run memtest overnight (to test all 8GB of RAM--which takes about 12 hours). However, I've read various places that memtest is only reliable testing one stick at a time (I have 4x2GB). I didn't get any errors in 7 passes with all memory in. Does this mean that I'm fine, or should I go back and test each individually?

If I place a single 4GB stick in my machine and run memtest, I see it's testing only 3.7GB. I assume this is the PCI memory map taking 0.3GB. Does this mean I'm not actually testing all the memory or am I missing something?

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.

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.

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.

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.

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)

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?

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.

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.

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.
