Pavilion dv7 programs closing and opening at random, computer stops randomly

I have a Pavilion dv7-6154ea running on Windows 7. I've had it for a year and a half now and I just encountered this problem (it started a few days ago).

The problem is that some programs or files are opening and closing by themselves, randomly without doing me anything. Sometimes even whole computer stops himself. And it's not as if it crashes, it just closes programs in the usual way or stops normally (without any problem).

I scanned the entire computer for viruses and it is clean. If the problem seems not be caused by a virus.

One thing that I was doing at the same time when this problem occurred is switchable graphics mode in the BIOS change, dynamics on fixed, by following the steps in this link to The switchable Graphics Mode

I have a built-in Intel GPU (that to speed up performance) and an AMD Radeon HD 6490 M GPU (that of better graphics) and I wanted to run the PC on the AMD because I think that the dynamic mode has not changed the GPU when I needded, for example for video games.

However, after a day of opening/closing by themselves programs, I decided to return to dynamic mode, and nothing has changed, so maybe it's also not the cause of the problem.

In any case, it seems too convenient that the problem happened right after I introduced the Switchable graphics in the BIOS mode, if I don't think it's a coincidence.

Can someone help me? It becomes very awkward to have a program that I use at the moment of the computer closa.

Thank you

sthri,

It doesn't sound like it's a virus, but it could also be the keyboard.

Go to start

Type ease.

Press enter

Go to the bottom and click, facilitate the use of the keyboard.

Check all the boxes and click OK.

The keyboard will not work, but move and open programs as you normally use the computer and see if you get any errors.

It is a shot in the water.

By clicking on the White Star congratulations on the left is a way of saying thanks!

I would like to know how everything goes.

Nice day.

    Problem webcam and HP SimplePass troubled can be tricky - when they don't work, it may be easy to fix - or terrible and difficult to understand.  I hope I can help.

    ===============================================================

    The camera can be other problems.

    The Support of your laptop troubleshooting Web site section:

    HP Pavilion dv7-6c95dx laptop / troubleshooting

    Help for Webcam / camera:

    Article > Webcam / camera

    Look at this document for help and suggestions:

    Laptop HP, Touch and PC AiO - Webcam troubleshooting (Windows 7)

    What happens if nothing helps?

    It is possible that the tiny wires in the camera are broken.  If nothing is done to fix the camera, you may need to consider that the wires that connect the camera to the computer are loose or disconnected (broken).  If that's true, in other words, if the wires are broken or disconnected, the webcam / camera will not work.  This isn't good news, but this is not cheap having fixed.  You can take the computer to a local computer repair center, the confidence of having this kind of work.  HP can also do this repair.  If you have the skills, you can do the repairs yourself.

    ===========================================================

    HP SimplePass

    Reboot = redΘmarrer

    HP SimplePass is sensitive to "other software" on the computer.  Everything must be "up-to-date" and ready to go.

    For example, you want to have your update of the .NET Framework, you want to have your updates from Windows Update (in the last month or almost) and you want to make sure that you do not have a shortage of pilots.

    For example:

    Page driver your computer laptop Support site:

    Category: Software - security > HP ProtectSmart hard drive Protection

    sp57232.exe

    Category: Software - Solutions > HP framework

    sp56878.exe

    The short answer:

    Preparation

    • Stop all programs: browsers, games, Applications, etc.

    Control Panel > display icon > System > System Protection >

    Select (highlight) your main drive (C)

    Click on Create a Restore Point

    Installation of the driver and HP SimplePass

    • Download the Driver of sensor of validity on your computer:

    sp56403 validity sensor Driver W7 - 64 bit V4.3.301.0

    • The pilot will probably download in your "Downloads" folder
    • Install the driver of sensor of validity by 'double click' on the name of the file
    • Restart the computer and log in

    Next

    • Download the version of HP SimplePass program 5.4.0.402 on your computer:

    sp58600.exe

    • Probably, the package will be downloaded in your "Downloads" folder
    • Install the HP SimplePass program in "double click on the file name.
    • Restart the computer and log in

    See if you can get HP SimplePass program to start

    ===============================================================

    HP SimplePass Version 5.4.0.402 is an older version of the program SimplePass.  Sometimes it works, sometimes it doesn't work for everyone.

    There is a newer version of the HP SimplePass program drawn up by the same company (AuthenTec) that might work.

    If you want to try it, follow these steps:

    • Download this program:

    sp63224 HP SimplePass V6.0.100.276 Win7-8

    • Probably, the package will be downloaded in your "Downloads" folder
    • Install the HP SimplePass program in "double click on the file name.

  • Pavilion dv7-2050sm: SSD and RAM upgrade questions

    Hello

    I have two question about upgrading my laptop. I use it for web surfing, movies, some excellent/word work etc... for the most part on a regular basis.

    (1) I have seen that my RAM can be upgraded to 8 GB. Currently, I am working at 1333 MHz 4RAM. If I buy 2 x 4 GB 1600 MHz will it work on this laptop, I went into the BIOS and have not seen that I can change the speed of ram anywhere nor has seen how much can this support for portable computers, so should I buy 1x4Go 1333 MHz instead if it only supports 1600 MHz.

    (2) can I put my disk HARD 700 GB Seagate 5400 RPM SATA II 3.0 Gbps with Samsung 850EVO 250 GB SSD? I know that SATA III drives are retro-compatible meaning can work on SATA II but is it useful, how much speed will I use if my laptop does not support SATA III.

    Laptop computer product number: B4E42EA

    Chipset: AMD A70M FCH

    CPU: Improved A6 4460 M to 4600 M A10

    Thank you!

    It will not run at 1600 mhz just so buy another 4 GB of DDR3-1333 memory. The SSD is the best upgrade you can do. Certainly worth. SSD SATA-III will work fine on a SATA-II bus. There is very little difference in actual operation.

  • Pavilion Dv7 - 3125sf BlueScreen and [disk hard Test failure]


    Hi James,

    I would run the DST short test on the hard drive again.  If it still does not respond, it is you say that there are areas of the drive that don't work anymore - that is to say that they cannot be written to or read.  From my experience, it is the beginning of the end for the HARD disk, because over time, areas more and more the reader will go the same way.  The speed and the magnitude of this decline is impossible to predict, but it will happen.  So to answer your question, I always install a new HARD drive, although as long as you do regular backups of your files - (make two backups so that if the drive has completely failed when refreshing a backup, you will always have the other is)-you can continue to use your existing drive until it becomes unusable.

    I hope this helps.

    Best wishes

    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .
