  • Radeon AMD in Pavilion dv7 notebook driver problem

    I have a pavilion dv7 notebook and for a few months, I had problems with my graphics driver.

    It began with a notice that my license was expired, so I went on the AMD website and tried to install the update. I ran dxdiag to find tool that I use an AMD Radeon HD 6620 G graphics card. I could not find my product on the list to manually install the update, so I tried the Downloader tool from amd driver and he had a problem of recognition of my graphics card. I then tried to update with the help of Support HP and that seemed to work for a while.

    Yesterday my screen changed the lowest resolution and a notice came it was not recognizing my graphics driver. Yet once, I tried to update manually from the AMD Web site. When this does not work I downloaded the driver AMD Downloader and after installing everything he said is that "your computer does not contain a correct graphics card" and closed the program.

    I am lost at this point uterally, and any help would be greatly apreciated.

    WARNING *.

    This is NOT official HP customer service and I, like most other people on this forum do not work for HP. It is a forum for users of peer-to-peer supported for class for the HP consumer products. HP maintains no official presence on this forum and it is unlikely that HP will respond in an official capacity. Response of an employee of HP represents his own opinion and not that of HP.

    AMD does not support the graphics system from HP to address personalized and won't provide any drivers for it. As a general rule, HP does not provide "routine maintenance" updates and usually only releases updates to fix known problems. You could take the computer to a professional, however they will be able to do anything more than I suggested and maybe even not so much than that.

    If you have any other questions, feel free to ask.

    Hello

    If you do not, use another PC to create a rescue CD Windows 7.  Download the ISO relevant among the links below.

    Windows 7 32 bit

    Windows 7 64 bit

    You must use an app like ImgBurn to burn the ISO to a CD - a guide on the use of ImgBurn to write an ISO on a disc is here.  One time created, or if you already have this, typing away at the esc key when you launch Notepad to open the Start Menu.  Insert the rescue CD.  Select boot options (usually f9), use the arrow keys to select the CD/DVD drive and press ENTER.  You can also get a prompt to "Press any key to" continuous - it if requested.

    When loading, select repair your computer and choose the command prompt.  When this charge, enter the following commands and press on enter after everyone – including spaces as shown.

    Hello;

    Let me welcome you on the HP forums!

    I read your message on the problems of file system on your new PC Win10 and wanted to help.

    There are two different issues that can cause this problem: the corruption of the file system (1) and (2) failure to road.

    Although it is a relatively new system, we will treat the second first following these instructions to test the hard drive: test a hard drive in the BIOS. HP® customer support

    My guess is that will succeed and the player will not display as failed.

    The first problem is more difficult to deal with, you will need to do the following:

    (1) remove the drive from your PC

    (2) connect the player to a job by using a USB of PC-to-adapter disk key

    (3) download and install this tool on the other PC: free Partition Manager - Partition Wizard Standard AOMEI software

    (4) use the tool to run a file system on the disk check

    If that does not solve the problem, while the PC is still under warranty, you must contact HP customer care directly so that they can put you in contact with HP Technical Support to see what they can do on the diagnosis and repair of your machine remotely.  If they determine the defective disc, you should be able to get a free replacement under warranty.

  • HP Pavilion m4-1001TX: startup problems

    Hello! My laptop is a HP Pavilion m4-1001TX. Recently, I updated my Windows laptop, 10 OS. Subsequently, I met problems white screen, which was resolved by resets hard (as suggested by various forums).

    A week ago, I met the same problem. However, I tried the suggestions (from hard reset, external LCD screen, BIOS recovery, for re-allocation of places the memory module). Whenever I start it, I can hear the hum of the fan 3 seconds, but then everything is silent. The power button and LED f12 button is down as well.

    Once again, Hello.

    So my laptop will not initialize correctly for about a month and a half, which led me to use my tablet.

    Anyway, it took me a long time before deciding to disassemble my laptop. Because ultimately, I could so he had repaired, I tried to check his parts. Verification of entrails, the fan is full of dust.

    After cleaning, the laptop worked properly. (FINALLY.)

    so for you guys, try troubleshooting step by step made by HP. However, if these things didn't work and your laptop is probably a year or two and you haven't cleaned his fan, you might as try though clean it by compressed air or disassembled.

    Disassembly, check the code of product in your laptop and search for it on HP Media tab. The research would generate some links, one of them showing a manual on how to disassemble the laptop properly. Follow these steps carefully.

    I hope this post helps you on about the start-up problems.

    NOTE: Disassembly for me is my last choice, so DO NOT REMOVE IT unless YOU REALLY NEED TO DO IT.
