Windows 7 update causes computer to freeze randomly

I have a Lenovo T500. It's a computer refurbished who came to me with the firmware of a Lenovo.

I am a student and I bought the edition of window 7 students. Since I installed it, the computer crashes on me at very random times. At first, I thought it was the bios and so I updated this. No luck. The computer hangs when it is connected or when using the battery. Sometimes this will happen in stages where Excel crashes but I still might be able to click on other programs. But when I try to save, close other programs or restart then the computer crashes completely.

I plan to do a clean Windows 7 install in case there is a conflict with some of the divers that Lenovo put on my computer. Is there anything else I should try first?

Windows Update has nothing to do with the upgrade of Windows.

  • HP Pavilion dv6 Notebook PC - mobile screen causes computer to freeze

    As I said in the subject, move the screen of my laptop causes my computer to freeze for a few seconds. Frost, I hear the mouse drags and moves in a few seconds the sound (if there is) is repeated on the sound current he was playing, and the applications are frozen in these seconds.

    When this gel would happen, I checked-> network adapters Device Manager and noticed that he was missing the devices "Intel Centrino Wireless N-1000" and "Microsoft Virtual WiFi Miniport Adapter". However, this could be because I checked it immediately when the computer starts.

    Now, I have noticed that this problem only occurs when the laptop screen is in a certain angle, or when I move it. I strongly suspect that this problem is related to the wireless network adapter. My reasoning, because it is because when I use the wifi (I use when wired at home), move the screen of the laptop freezes as described above and the wifi icon immediately shows that the device is disconnected.

    My question is: what can I do to correct and prevent this problem from occurring again in the future? I've updated the drivers by clicking on the "Update Driver Software" option when I right click in Device Manager, which could be a problem if they are not compatible with my device.

    Hello AndrewGG,

    Welcome to the HP Forums!

    I understand that the mouse will be late when you move the screen. This issue is pilot or associated hardware, and without being there to test it, I wouldn't be able to check 100% of certainty.  I did some research on this issue. Unfortunately, the only reliable troubleshooting which remains is to reinstall the operating system. Too, there are different issues that could be causing it. Reinstalling the operating system will address all, unless there is a hardware problem.

    First, please save all the files you need. You can find specific steps on how to proceed in the following HP document: backup of files (Windows 7)

    Once this is done, you can safely reinstall the operating system. I'll also give you a document on how to do it: perform a recovery of the system (Windows 7) HP

    Please let me know how it goes. Thank you!

  • Windows Vista - update causing high memory usage

    I got the pages of updates over the past two years. I think the volume of updates had a negative impact on the use of memory and the computer takes an extremely long time to boot and load anything.

  • Windows Vista update causes applications non - IE to be denied access to the internet

    I have a laptop Lenovo IdeaPad Y510 unfortunately comes with a Windows Vista Home Premium OS that has caused me a lot of problems with conflicts between her and others, package applications, and now I am forced to use my network at home for route information and documents that must move through the internet by sharing them with another computer Windows XP which is also configured exactly as my Lenovo IdeaPad Y510. I look forward to wean myself off of all MS products, possibly other that MS Office, I use a lot and plays always well for me to wire many years and updates/upgrades. Not the same for MS Windows Vista, however. My experience, similar to many other forum users, has been constantly frustrating over the years I've had to deal with it.  I lost a lot of time dealing with problems caused by code errors in the last set of MS Windows Vista updates that made all my package applications that require internet access unusable.

    I contacted the support of Lenovo and support forums for my problem, and they too cannot provide all the answers that address this issue that is causing me to spend much too much time I could use to work at a rate of $65 / hr, so you can see that this is not only an inconvenience.

    Before someone points me to the myriad other similar positions for possible answers, let me say that I probably have alread read it and tried all the suggested actions, without success. I need to REAL answers and REAL support, and I need it NOW.  Also, I don't think I should have to pay for the support which has been made necessary by the negligence of MS to test their updates for compatibility issues with the popular, free package critical applications for the safety of MS OS system of a user, such as AVG Free antivirus, ZoneAlarm Free firewall personal , OR who are competitors for their navigation on the web or by email client applications. I am not now under the other another firewall that MS Vista firewall having had to uninstall my firewall ZoneAlarm Free. I even had one of my other previously compatible and effective anti-malware/spyware apps, AdAware, uninstall Lavasoft. No matter what I did, which was suggested to me by MS resources support or Lenovo support resources, this problem, which began shortly after the last round of all the months of downloads to fix security and facilities, persists and cost me more money in revenue and lost time every day.

  • Hard drive failure / security of Windows 7 update cause?

    Hey everybody. I'll try to keep this brief. Long story short, I got random shut off for about 2 months and we try to find the problem. Recently, I just replaced the motherboard, and because these are my 2 power problems. Just before we have replaced the. My hard drive has worked very well. But now, we think that my drive broke down. Because my car does not start, sometimes on startup Windows and accidents but my father got a hard drive from a laptop broken in the street and the computer starts without a problem. We have a new album on the way. But how do I get my windows 7 out of it. I always have my product key. My father read the Windows 7 security update was causing this issue? If anyone can help me, thank you, I really just need to know if/how to get my Windows 7 in the new drive or if it is possible to get all the data there. thanks to all.

    If the new motherboard does not have a processor and chip set identical or nearly identical, your Windows installation may not work due to an incompatible Abstraction Layer HAL.  The HAL is customized during the original installation.  Some backup software can do a restore to a different system, but it's a different situation than to try to use your player in this way.

    If your installation of Windows is OEM which also triggers a license problem and cannot be transferred to a different motherboard.

    Data can be recovered by using a bootable operating system or connection to a drive to another computer by USB or directly. This mechanism can also be used to retrieve data.

    I feel for your message, it would be preferable for you to get professional help with your computer.

  • Latest version of iTunes causing computer to freeze

    The latest version of iTunes crashed my computer every time.  I opened iTunes and after a short moment, everything freezes, even not work Ctrl + alt + delete. I have to manually restart the computer may.  Twice I had to use a bootdisk just to bring it to the top.  I tried to remove iTunes and reinstall but it does the same thing.  If I don't run the program, my computer crashes.

    Windows 7 Professional 64 bit

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. When reinstalling right click the installer downloaded and use run as administrator.

    Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

    The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

    Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

    To switch to safe mode see the link given below

    Try to go to safe mode and check.

  • Computer screen freezes after inactivity

    I recently did a free my Norton anti-virus update to the new version 2011. After this update my computer screen freezes like 1 or 2 times a day. It occurs normally after I put mode "Eve" and go back to using it. After about 15 to 30 seconds, it will freeze sometimes.

    I don't know if it's related but I got a DEP Data Execution Prevention, pop up, but not when the screen froze. I performed a complete analysis of the system of Norton and not detected no viruses.

    I wonder if this new version of Norton has problems with windows? I use my computer for e-mail and the Internet. Do not download music, games ect...

    Any help would be appreciated.

    On your download Norton: I had similar problems and discovered how to do a clean install by getting rid of that most completely in the control panel and task bar completely so we start with the most recent. If you do not buy on line and using the disk, Norton technicians will likely send e-mail instructions since it's their program.  But read on some similar experiences I've had, it might help you.

    I finally got the taskbar, moved to the bottom of the screen, but in the meantime, I downloaded a software called ParetoLogic who claimed that he could fix the taskbar, but he did all the scans and has not set something on the taskbar, so I deleted and kept following the instructions in the task bar and got moved from the task bar.  Then I uninstalled the software called ParetoLogic, my office has begun to gel.  I have to shut down the computer manually, so I contacted the technician on their site and they sent instructions to fetch the menus of tasks that were set to run and the record, but when I finally found the tasks, I couldn't delete them.  I tried to close the Task Manager and he said that I could not close file until all dialog boxes are closed, and I could not find how to close the dialog boxes.  I do not know how to find it after searching for the bar of tasks and answers questions, so I had to click on restart and shut down everything, so I probably lost some information on the way.  I had a computer to lock my CD drive there are several antivirus and anti spyware software, making a few years I used McAfee more Att security program free that they have downloaded with my DSL internet. I didn't know until you have to do a clean uninstall before you try to download a newer version. The control panel will not remove or uninstall all of a program, there are always parts of it, still running in the system, and that's what happens to me today, so, maybe if clean you the old version first, then do a clean with the more recent, install which will probably do.
