Rolling back recent updates to Bios, Vid, its driver

In my attempt to get my Blu - Ray player to play Avatar BD, I followed the instructions and attempted to try to operate by updating the Bios, sound cards and video drivers. I received the new bios installed, new ati catalyst center installed graphics card drivers installed and sound and it still does not. In addition to this, the new drivers audio and video are spoil when I watch the video on my TV via hdmi. Before the update, when I have quand j' ai branche plugged my laptop to the TV via hdmi the sound would automatically change between the helmet speaker hdmi and s/helmet back when I unplugged the hdmi Jack. Now, it is not switch back as it did before. In addition, the return video playback worsened and the picture freezes during video playback, where it didn't before.

So, I would like to know how I would go about the return of my system to a point before I updated all my drivers and BIOS. A system restore will allow me to return to this point or I have to uninstall manually all of these updates. Is there a document on how to manually uninstall the bios drivers audio vid? I tried to remove the graphics card Ati catalyst centre and it seems to have uninstalled but it did make a difference. Now I wish I did a system restore before dvd I made all of my updates.

Any help on how to get back to where I was a few weeks ago would be greatly appreciated.

My system

DV5z-1000 CTO

BIOS F.38 was 37 before I think.

ATI Radeon HD 3200 (driver 8.476.0.0)

To restore your system to where was go to the Control Panel, switch to the display of the icon and find the 'recovery' and go to the system restore. Follow the windows and choose a custom restore point to where coincide when everything worked normally.

The BIOS is not affected by the Windows system restore, but if everything is back as it was, then let the new BIOS only.

Here are a number of versions of BIOS. One you have before is listed is there if you need it.

http://h10025.www1.HP.com/ewfrf/wc/previousVersions?softwareitem=ob-80499-1 & LC = on & DLC = in & CC = US & os = 4063 & Product = 3759541 & sw_lang =

Once you've done all that and everything is back to normal, uninstall your Media Smart DVD, reboot and install it:

http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-83335-1 & LC = on & DLC = in & CC = US & os = 4063 & Product = 3759541 & sw_lang =

Then reboot, and I hope that you can play Avatar. I use this version on my dv8 and it works, I hope this will solve your problem.

  • Can I roll back after updating to Windows 8?

    I am very happy to upgrade to Windows 8, but I'm afraid that my graphics card might not work with it. I tried the preview and was wrong with it. If I install Windows 8 on top of Windows 7 and the card does not work, is it possible to go back to Windows 7. So, I'd rather not dual boot it because I would move in Windows 8 with all my programs and files already there.

    Hello SebastianZHD,

    There not a roll-back feature to return to Windows 7 of widows 8. It will be necessary to reinstall Windows 7 from the installation media.

    Thank you

  • PC HP Compaq 8200 Elite MT: Should I roll back before flashing the BIOS?

    Hello, I am trying to determine if the update of the BIOS shown on your website is right for my machine: HP Compaq 8200 Elite MT PC. After selecting 'Let HP find my products,' he identified my machine and sent me to a page that asked me to 'Select language driver and OS' two squares. I selected my language, then going on to the next box that asked me to choose my operating system. However, it does include all the Windows 10 selections. I used to have initially Windows 7 Professional. However, I've recently upgraded to Windows Professional 10. Is it safe select the operating system Windows 7 Professional, even if I is no longer on the machine? You see, I want to update BIOS, because I'm having trouble starting after I install memory upgrades, and the provider of the RAM is recommended to upgrade to the latest version of BIOS upgrade before installing the upgrade of RAM, to eliminate these problems. I don't want to make a mistake, and then select the wrong BIOS update. There is an update of the BIOS on HP.com for my MoBo machine, but only for Windows 7 Pro. So should I go back to 7 Pro, before the update?  Please, inform me as to what I should do.

    Hello:

    I just got the flash drive, I use to update BIOS on my HP business desktop PC.

    I plugged in my dc7800 CMT W10 also running.

    The window on the flash drive, and I closed it.

    Then I went on the desktop, click on this PC, click with the right button on the flash drive, which is drive E:\ in my case.

    Then I chose the Format from the menu, and a box will open.

    In the file system drop-down list that I get on my USB flash drive, I get the following options:

    FAT (by default) which is what you want to use.

    NTFS

    FAT32

    exFAT

    So if you don't see these options, try another flash drive.

  • Satellite U400 - PSU40E Synaptics touchpad problem after the recent update to BIOS

    Toshiba welcome,

    I've tested this in reverse, this is why the statement in the subject as it looks. After upgrading the bios of 3.00 to 3.50 touchpad loses its precision. Very rude and useless its like that.

    I tried different drivers, everything, but the only way to really solve this problem was it downgrade to 3.00 OR uninstall the driver Synaptics completely. Second solution, unfortunately, is unacceptable, because then I lose some features, like click on contact, which I don't use and control.

    Best regards

    Wojtek

    Hey Buddy

    I U400 and the BIOS has been updated to the newest one.
    The touchpad works like a dream. I m using Win XP and Vista and there is NO problems after BIOS update!

    In your case, this may be only a software problem and I think you can use the Toshiba Recovery disk and could reinstall the whole OS from the Toshiba drive

    It is a really radical solution because the whole HARD disk may be formatted, but if the resettlement of these two drivers touchpad didn t help then I think this would be the last solution.

  • How to roll back the update of Firefox 29? I hate it.

    I got the update of Firefox 29. I don't like it and removed features (for example, the bar add-on). How to restore? I have to completely uninstall Firefox?

    Hi netscaper, several years of research with users went into this redesign, but of course you may not all agree on the same thing.

    As a small non-profit organization, Mozilla doesn't have the means to do everything herself. Firefox has since always the philosophy of trying to keep the lean browser and allowing for customization through modules. Sometimes the ride is bumpy, but generally you have several ways to do the job.

    If there are special features that are essential to bring back into the product itself, please give your comments here:

  • Roll back the update of Silverlight

    On 29 September, Microsoft Update has eliminated an update of Silverlight. I suspect that it was the cause of the changes in functionality in a program that I use, so I want to uninstall this update to conduct tests. How can I do this? It doesn't seem to be installable via Win7 Pro 64-bit programs and features.

    I looked at the Hp site but could not find an update for my bios.  Mobo is Foxconn Eton 1.0 and the Bios is FRIEND 5.05 25.09.2009

    A scan utility (Bios Agent) indicates that there is an update, but they require payment for flashing the bios.  In case I have some concerns, and many would prefer to download Hp or Foxconn.  I looked on the sites Web from Foxconn and FRIEND, but they require a lot & a lot of information that I don't have and don't know where to find them. I was hoping someone might have the same PC to give me information.

    Also to install the disk SSD drive I brobably would need an adapter to allow the reader to 2.5 inches to fit into the drive 3.5 "bracket. Apart from this, the connectors on the SSD drives all seem to be the same.  is this correct please or will it take a SSD and a specific to my PC case and my existing hard drive adapter.

    Thank you

    Hi thanks for your help, advice and information: my PC was purchased in January 2009 is a little more than 4 years.  The upgrade would cost 130 pounds. I could not buy a decent PC with 4 GB ram and an SSD for under £500.   I do not download music or movies, or make more than a small base video editing so I'm sure that with these improvements, there will be more than enough for me.

    One thing doesn't bother me.  It seems that when buying a PC Bios updates are available for the first 2/3 years, but not thereafter.  It would not have occurred to me to look for an update of the bios, during this period just simply because I thought that they were issued only when necessary to take into account improvements and new technologies so thanks for that. you live & learn.

    I'm trying to teach me the 'nuts & bolts' repair and fix PC problems and I guess that's the main use for my PC.  Experiment with a new £500 Pc would scare me to death.

    I'm on Linux Ubuntu 13.1 without any problems on my PC Dell 9 years and XP Pro on my HP Pavilion 13, so maybe I can do my Compaq last a little longer.

    Once again thank you very much.  its part of the process of learning.  see you soon

  • Roll back the firmware update

    Hello

    Is it possible to roll back the update of the firmware? I put on the Hebrew firmware 01.01.15 - I was wondering if I can take that off and put that ordinary English? Is it possible or do I just wait for the next firmware update and use English? I was told to look at the other posts here so that he can recognize the Hebrew he needs to UTF-16 encoding - but my s/w EasyTag for Linux can only do utf16 for id3v2 and the "rocket" uses only id3v1 correct?

    I am so frustrated with this.

    For a manual installation of firmware, simply unzip the compressed firmware file and place it in the root directory of the "rocket".

    When the rocket starts, it performs a check for a new firmware file in the root directory.  If you have placed the file in the root, it will automatically replace its current firmware with the one you have placed there.

    This can be done in MSC or MTP mode.  The only difference with MTP mode is that you first need to double-click on "Internal memory" to access the root durectory.

  • After updating the BIOS, speakers produce no sound and iTunes and WMP did not recognize media files.

    Hi people. I got an update of the BIOS that has been installed automatically today. Since the update I lost all sound to my speakers and for the most part, my headset plug into the socket. I ran troubleshooting (States that the speakers are working properly), I rolled back and updated the drivers audio, quadruple checked all the settings, did a hard reset... nothing seems to work for her. Have no idea while iTunes or WMP won't play all my music now. Any help would be greatly appreciated. Thank you! (I have a HP Pavilion dv7 entertainment notebook running Windows 7)

  • X200T not boot from any device after updating the Bios v3.00

    Hello

    I recently updated my bios to the latest version, the v3.00 X200T and now it does not start from any device - everything I get a blank screen after the initial bios starts upward.

    The bios seems functional and it recognizes all the devices I attached, as well as the internal hard drive. However no matter how to start the machine it does not start. I tried to set the boot order in the bios, using F12, F11 for recovery, remove the internal HARD disk, used all the USB ports, etc... -all I get is a blank screen after the initial splash screen.

    No beeps to indicate any problems, and I tried to reset the default settings of the bios, remove battery & power - all to nothing does not.

    Any ideas?

    I updated the bios of many laptops and desktop computers in the past, but this is a new one on me...

    I hope someone can help.

    Darren

    It seems that it also happens to X 200 owners who upgrade to version 3.01 of the Bios.

    mc2sgp has posted a response in this forum that worked for me:

    "I have the same problem and found the way to a temporary solution."  Go into the BIOS (you should always be able to press F1 to go into the BIOS) and go to Config-> CPU Intel VT - d characteristic of-> and disable it.  You should now be able to start normally in your operating system. "

    At least, I can now start my camera.

    Hope this helps others.

    ADMIN edit: tagging this post as the solution to guide others to the bypass.  Lenovo will remove the BIOS on the web and replace it with an updated version that resolves these symptoms as quickly as possible.

  • Laptop HP 15-r001tu: updated the Bios PC portable HP 15-r001tu

    My laptop randomly makes automatic update of the BIOS recovery quite regularly, perhaps every two weeks, so I was wondering if this could be a problem with my laptop should I get extract? Or if it could just be normal? Thank you.

    @Kay7

    It is not random. The HP Support Assistant is usually set on install updates, as appropriate, on a weekly basis.  I took a glance at the available on the web portal of suport BIOS updates in the section downlolad. I saw that in May there were six the available BIOS updates. I highly recommend that you turn off the automatic updates in Suport of tune.  Who will take care of the issue and put control of your laptop in your hands.

    The HP Support Assistant is the only clean utility that your laptop comes able to update the BIOS on its own. Only install BIOS update when there is a reason and not just because a BIOS update is available. It is under the heading of don't fix it if it is not broken or it could break

    When the HPSA is put in place in order to review and approve the updates, you should see an icon like the following in the systray down by the system clock.

    This is the update that he wants me to take a look at review and choose to install or not.

    Advanced options HPSA. Make sure that no automatic option is selected.

  • Looking to update my first internal hard drive 2011 MBP

    Instead of recently updated to a new external drive.

    I thought it may be time to update HDD internal (500 GB) original on my MPB.

    I have 8 GB of RAM and internal light enough to keep my drive in without worrying about storage and applications.

    Everyone updated their MPB HDD with a 7200 RPM disk or an SSD?

    If so, what drives internal you would very recommend?

    Search for better performance and faster read write time.

    My 500 GB drive is barely filled. There are currently about 150 GB of data used.

    Much appreciate your comments and experience once the internal drive has been updated.

    Ant case 2.5 "HDD or SSD will be compatible with your MBP.  Here is just one example of what is available:

    https://eShop.MacSales.com/shop/hard-drives/2.5-notebook/

    Maximum capacity at the moment is 2 TB, enough for almost all users and by eliminating the need for storage of primary data on an external drive.  I currently have 1 TB SSD Crucial in my Mbps in 2010 and 2011.  Would they change a profound impact on the performance of the computer.  If the bank account is fat, install an SSD.  If not, faster turns HARD drive will be better, but not as much as the speed difference may suggest compared with the 5400 RPM HARD drive.

    Based on reputation, the best currently available SSD is OWC and Crucial.  Although I prefer HGST and Seagate HDD, one brand will do that are listed in the link I have provided.

    As a side note, your MBP will support up to 16 GB of RAM.  OWC and Crucial are the best sources for RAM Mac compatible.

    Ciao.
