The HP Pavilion a6560z bios update

I have a HP Pavilion a6560z. Product #: KZ851AV

I tried to upgrade the processor of double base installed to a phenom x 4 9550, that my research shows is compatible as long as I have updated the bios. I am currently running bios version 5.14 20/06/2008. My problem is the OS original on this PC is Vista, I erased this OS and now run Win 7. I found an update of bios, version 5.49 but she said do not be there except if Vista is installed. Will install this bios brick Council since its desingned for vista?

I can't enter the bios with the 9550 installed but it does not start in windows. The bios shows that it is a blah blah Phenom quad core, so at least he acknowledges that, but when I try to load windows it says "the file is maybe damaged. The file header checksum does not match the checksum calculated. "I read that had a memory problem and tried 8 different sticks, all with the same result, so I thought it was a bios problem. Anyway, any help on a version of bios, I can try without bricking advice would be greatly appreciated. Even if its for Vista that I am always willing to try. This pc is not much of value. Thank you.

You are welcome.

Thanks for the quick response. Last question, if I could somehow reinstall Vista (system recovery is not an option) and then perform the bios update I was able to install windows 7 and then continue with the new (er) cpu?

I checked the page download software & driver of the computer for an update of the BIOS for Vista and Vista 64-bit.  It seems not to be available.  You cannot use a retail BIOS update.  Where did you find a BIOS update?

  • The accident of the L50 - A satellite BIOS update

    I have a portable Satellite L50-A-10W with win7 64-bit.
    A few days ago the Tempro software began to show the message, a new BIOS update is available, that I downloaded. After clicking on the file .exe, Setup window popped up. All right, the computer restarted and began to Flash the BIOS InsydeH20 utility.
    Progress was indicated by a line:
    Progress update: counter.
    The problem is that, once the counter reaches 100, the progress has stopped. Nothing happened for several hours now, and the computer does not respond to what either.
    (I even tried force stop, pressing the power button but no response.)
    Any ideas what I can do now? Someone at - it had similar problems?
    Thank you in advance!

  • HP Pavilion A6750Y Bios Update for Windows 7?

    Hello, I bought a HP Pavilion A6750Y years that I have been very satisfied.  I have of course updated from Vista to Windows 7, added a video card and I'd really like to upgrade my cpu.  So far, in the Support & drivers for my computer, it lists still my motherboard as being able to run up to a processor AMD Phenom 9950 x 4. I noticed however if I list my OS as Vista 64-bit, then it does in fact appear a BIOS update that would allow the MOBO to exploit some AM3 cpu. It would still work for my computer running Windows 7, or y at - it an update of the BIOS in preparation for Windows 7, otherwise I would really like to make the request. I want to spend my processor to a Phenom 2 x 4 and need my MOBO to support AM3 processors. Thank you in advance.

    Hello:

    I wouldn't update the BIOS by using Windows 7. There is more than 95% of probability you will make the PC unusable.

    HP will release no updates to the BIOS of windows 7 for your PC.

    If you want to update the BIOS, your only alternative is to install Vista, updated the BIOS and then reinstall W7.

  • Where can I get the 29CN26WW (V2.03) BIOS update for a G560?

    It is not listed on the site, & I need to update to the latest. Thanks for your help.

    I understand that I read that info, it does not help much because the v2.03 file is no longer available.

    * edit * Nevermind I was able to find the file in a strange way. Here is the link if anyone ever needs her. If you need the 32-bit version, I guess you can cancel the download, look at the URL & change to NIWEx203_x32.exe for it to work.

    But after the update, my CPU fan speed is faster then normal and make a lot of noise (even if the CPU is cool) when I use Windows 7 is still stay on fast speed making a lot of noise.

    Do we sort of degrading the BIOS or thw way to earn the slow CPU fan speed?

  • Di Shutdown does not work, got the blue screen, beware, if it's the 1st time, etc., bios .updated .shutdown worked for awhlie, then got the same blue screen on another attempt to stop

    I had trouble with the fans so I unplugged everything, pulled out the memory and put it in. Shortly after received warning on a stop. I've updated the bios and things worked fine for one night. The following day I uninstaaled some programs and blue rebooted and got the screen again. I can right through the blue screen and sign, but have to stop with button / stop.

    Hello

    What is the exact error message on blue screen?

    This error message can point to a hardware or software that causes this problem. If the computer restarts after the Blue error screen, disable the automatic system failure restart option allows to capture the error message on blue screen.

    Check if the problem persists in safe mode and after the same return.

  • XPS 15 9550 CPU speed is as low as 0.75 ghz after manually installed windows 10 with all the drivers installed and BIOS updated

    I just bought this XPS 15 9550 in January, and I really appreciate it at first.

    However, one day, as pushed microsoft update to 10586 version of windows 10 and the machine will always fail to install the update, so I decided to download the image file and install it myself.

    The installation went smooth, but after a few days use, I found the computer is very slow during playback of videos and games and I came to find the speed of the CPU shows the label of performance in the Task Manager always will be 0.75 ghz and 0.78 ghz. He cannot go above that. I also found that the use of the CPU cannot exceed 30%.

    I've already updated my BIOS to 1.1.19, reinstall the system, a few times, choose the battery mode high performance, etc and this does not help.

    I also downloaded the power of intel and found gadget for my processor power consumers are still weak and the speed of the CPU is always not 0.80 ghz.

    In addition, I encountered the problem that after plugin the AC power, the speed of the CPU will fall to 0.39 ghz...

    Someone at - it an idea of what is happening here and how can I solve the problem? I'll really appreciate it. Thank you.

    I had my problem is solved. Follow these steps:

    1. download gadget power intel, you can search online for it.

    2. check the power of your CPU (package pw...) rate and open the videos and applications that will constantly consume the CPU power. See if the power is still weak.

    3. If the power is still weak, try to update your BIOS (download dell drivers and the new version should currently be 1.1.20) and see if things are getting better.

    4. If the power is still low, you must contact dell technical service to replace your hardware (my computer has replaced the northbridge, southbridge, I forgot, but after replacing, the CPU works fine)

    Note: If you run games using your discreet graphics card, such as starcraft II and you found that it's extremely slow, it is possible that your cpu is capped.
