Windows 7 32 bit does not recognize 4 GB of RAM

I just bought a new w500 with windows 7 32-bit and 4 GB of RAM, I know that windows 7 32 bit must be able to work with 4 GB of RAM, but when I check the Windows System Control Panel 7, he said: installed memory 4 GB, usable memory 2.46).

When I check my setting of the video adapter it says 512 MB dedicated memory and 1024 MB shared memory.

I don't really know what to do, I don't know I used the 4 GB ram with windows Vista Ultimate before and it was OK.

He was everything to solve this problem? Do I have to install a 64-bit version of my windows 7 pro?

If I is there a way I can install it with the serial number supplied with my laptop, so I don't have to buy a new version of windows, I've just will download and install a 64-bit version of windows 7.

-Besides, I'm not 100% sure, but when I got the laptop, on the Panel of the system, he showed that he uses all the 4 GB of ram, after 1 day of use and when all Thinkpad and microsoft drivers updates have been installed, what happened.

now, just please help me and tell me what I need to do?

You probably need to transfer activation with something like ABR unless the key works for both versions now. Retail Vista keys worked for 32 and 64 bit version but haven't Lenovos OEM key.

Regarding your 2.46 GB of ram - I the only thing that indicate is that Windows is telling you the truth its time. There is no way any 32-bit system can use full 4 GB. Information system in Vista have generally shown only to installed RAM without showing the usable memory. They fixed in Windows 7, and now, he can tell you the exact amount can be used. But that doesn't change anything but your taking of consciousness of the fact.

Oh and when I was using Vista 32 it showed the / 3 gb in a first time and then went down to 2.46 I was installing graphic drivers. Switchable graphics driver supposedly did this and some users have reported that uninstalling / installing different drivers, but I prefer to install windows 64-bit for peace of mind.

    Some other HDD is recognized correctly?
    What you can try is to reinstall the chipset driver, restart the laptop and test it again.

  • Windows 7 64 bit does not recognize the Seagate Plus 2 TB external hard drive backup

    I am unable to get my laptop running Windows 7 Professional 64 bit to recognize my 2 TB Seagate external drive. Seagate tech suggests that I need a chipset driver-whatever that is. I tried many times to install Acronis DiscWizard, but get a fatal error message. I had no problem to install on my desktop and perform the backup. It takes also place W 7 Pro, but 32-bit. Help!

    I reformatted the drive on my desktop to make three partitions: one for my office, one for my laptop and a spare part for what I might need to. Then, I downloaded DiscWizard on Seagate website. It works on my desktop, but not my laptop. My laptop is a Vostro 3550 about three years, and I've never had other USB connection problems. I tried all three USB ports and none works. My office is older, about 6 years old.

    The error message is the following

    Installation failed

    Fatal error during installation

    When I tried to install DiscWizard. I wonder if the fact that my office is 32 bit and my laptop is 64 bit is a little difference. I installed first DiscWizard on my desk.

    Windows XP Movie Maker does not recognize my camera Canon HF R10.  Canon is also not listed as a brand for the digital display when I connect the device to the computer.

    =========================================
    Movie Maker has been designed to download from mini-DV cameras
    connected with FireWire... (they record at small cassettes... not
    flash drives)

    The best would be to download the video files in a folder on your
    hard drive... convert the WMV movie format and then import
    in Movie Maker.

    If you connect the camera via a cable USB and go to... My computer...
    It should be recognized as a drive. If it's... you can download it from
    there by copy and paste or drag and drop.

    Good luck...

    It's sad to see how Samhrutha answer to the question in this way.

    The driver does simply not good.
    The only option to address this situation in the meantime a driver that works, disable features in ' Configure, Advanced tab "on the actual card.
    Different properties exist here. Try to enable / disable some of them. It helped for me on Win7 x 64 ASUS MB.

  • Windows 7 Starter Edition does not recognize a hard drive WD

    Windows 7 Starter Edition does not recognize a hard drive WD, I used until last month. Device Manager sees it, he sees the USB controller (it lists as a mass storage device), but I can't access the information on the hard disk, or make use of the last backup. I tried to uninstall USB drives - it is not the thing. It gets listed under disk drives.

    Thanks for the reply.

    There was no error message: the device has been recognized (listed) by the USB controller and the Device Manager, but not by the management of the disks - so I couldn't access.

    I managed to fix the problem after:

    -J' scanned the computer (DELL Inspiron) with the Safety Scanner
    -J' completely uninstalled all the software associated with an external hard drive
    -J' uninstalled the USB controllers
    -reboot the system
    -reconnected the external HD
    -After gaining access to the drive, I installed the dedicated software

    Best regards
