Windows XP, when started, do not recognize all of RAM

The BIOS says I have 512 MB of RAM, but when Windows XP boots completely and I check the properties on my general tab of the computer and I said I'm only 448 MB of RAM. The first times before my departure for the BIOS Windows XP said I only 248 RAM initially. What is happening with this? I realized that what was going on when I went to install a program that requires at least 500 MB of RAM and insofar as I had only 448 MB of RAM Windows XP says it would not install. Why Windows only recognizes only a part of my RAM and how I can fix? Windows seems to work perfectly, even if he does this. I can't understand what is happening. I have a HP Compaq Presario SR1620NX. If anyone can help the right answer, it would be GREATLY appreciated.  :-)

Welcome to the forum.

The on-board computer video.  Video memory actions integrated memory system.  Therefore, a part of the system memory is not available to be used by other programs.  The only way to solve this problem is by opting for a dedicated video card.  This adds the video card memory and removes shared system memory.

  • Windows 7 "Playback devices" do not recognize all options of reading?

    Hello

    I just changed my motherboard to a 'Gigabyte Technology Co., Ltd. model EP45-UD3P (Socket 775)"because my previous motherboard my have broken, (now I think that he could have the power supply, go figure).

    In any case, during the installation of the Windows 7 OS it have no sound options connected to the motherboard. The first audio option that I hung has my Philips flat screen TV via a HDMI cable to the video card. This was immediately recognized.

    Since then, I've hung up a Toslink cable to fiber optic to the motherboard to the receiver, this is not recognized at all.

    The only option that appear when you right click on the sound icon raise all the audio options and clicking on the 'reading devices' is the HDMI video card on television.

    Why Windows 7 will not be recognized the Toslink or analog options at the back of the motherboard?

    What can I do to fix this?

    I tried the tool audio Microsoft fixit, but nothing happened. Please, is there a way for it to work properly. Thank you.

    John

    After contacting the seller on eBay and them, which suggests looking in the BIOS I was able to get all the play back option to appear to "activate" the audio option under Advanced options in the BIOS.

    The seller said that this motherboard has already been used in a HTPC (Home Theater PC) and only the HDMI necessary option available.

    Here, the issue is resolved and I am able to listen to my music and movies through the optical audio or Toslink option so I'm a happy camper!

    Now, if only to get the IR to work with the remote for their 2250 Hauppauge TV card.

  • After Effects does not recognize all the RAM

    I just installed After Effects on a new PC with 6 GB of RAM, but it says on the splash screen that appears when loading of the AE x % of 4 GB of RAM used.

    I have to do something to see 6 GB?

    Thanks in advance.

    Assuming you are using a 64-bit version of Windows.

    AE is a 32-bit application.

    In preferences, there is a setting for the memory and multiprocessor.

    Check that out and it will be wrong on the 32-bit limitation by launching several nodes rendering AE.

    However, this setting seems to come with its own problems of stability, in my case anyway.

  • Noron 360 sometimes cannot be started on Windows 8 when starting after a stop!

    Hello

    I have a desktop computer running Norton 360 first Edition version (current) 20.4.0.44 with the latest definitions for viruses on Microsoft Windows 8 Professional with Media Center. Norton 360 , sometimes fails to start on Windows 8 , when starting after a stop.

    Since I first installed the new version of 'version-less' 2013 Norton 360 on Windows 8, it sometimes does not start at startup after a stop and did not bother to mobilize support for that matter because I thought that Symantec or Microsoft could be aware of the problem and that an update or a patch will be available soon. Norton 360 prompted me to apply a new patch today, and after applying the patch, I have realized that the amended version of the version 20.3.0.36 to version 20.4.0.44. Moreover, I also noticed that the aforesaid problem with Norton 360 persists, and if my memory is good, Norton 360 sometimes also does not start after the resumption of hibernation. I used to put the computer to sleep and I never have this issue when hybrid sleep. For Norton 360 upward and run again, I usually just give the computer a reboot.

    I believe that the function "quick start" in power options Windows 8 are originally Norton 360 sometimes fails start. I haven't noticed this problem on computers that are running Windows XP or Windows 7. If Symantec or Microsoft may arrive at a solution to this problem without having to turn off the quick start of Windows 8feature, I would be very grateful!

    Kind regards

    If you connect the camera via a cable USB and go to... My computer...

    I am a user of hearing CC/CS6 and want to burn the MP3 files on a CD - R using either version.

  • Why not Windows Media Player 11 does not recognize w4a files in the library list more.

    I have Windows XP Pro (SP3) with Windows Media Player 11. I had a virus wipe my hard drive (everything has been updated) and after reinstalling and updating everything, it no longer recognizes the w4a files, but it automatically plays them the OMP 11 if I click on the file in Windows Explorer.

    Before the accident, all the files on my computer w4a was included in the library. Now the entire albums, as well as individual songs are missing. In fact, now NO w4a file is listed. So my question is, why does Windows Media Player 11 recognize the w4a files?

    Neil

    Hello

    Method 1: I suggest you try the steps from the link below and check if it helps.

    a. close Windows Media Player.
    b. find the file of database on the computer that contains the entries of your library. In general, the library database file (CurrentDatabase_219.wmdb) is located in the following directory:
    (Drive :) Users/xxx(the user name)/Appdata/local/Microsoft/Media Player
    c. right click on the file and then click Rename.
    d. rename the file by changing its file .bak extension.
    e. start the player. When you do so, a new database of library file is created.
    f. press F3 on your keyboard to open the add to Library dialog box search for computers.
    g. click the Browse button to search for a folder on your computer that contains digital media files. Specify the location of the folder in the box look in.
    h. click on the search button.
    The player will search for digital media files and playlists in the folder you specify and add to your library. If you have your files and playlists stored in different folders on your computer, you may need to search for files several times, by specifying a different folder every time.

    Method 2:
    You may need to rebuild the database of Windows Media Player.
    Here's how:
    To resolve this problem, delete the Windows Media Player database. To do this, follow these steps:
    a. exit Windows Media Player.
    b. Click Start, run, type %LOCALAPPDATA%\Microsoft\Media Player and then click OK.
    c. Select all files in the folder and then click on Delete on the file menu.
       Note: You don't have to remove the folders that are in this folder.
    d. restart Windows Media Player.
    Note: Windows Media Player automatically rebuilds the database.

    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

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

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD

  • Windows 7 password problem: does not recognize password after waking from sleep

    So I have recently buy a netbook with Windows 7 operating system. I create the administrator account and password protect. All right, install software, copy documents, etc. in the "My Documents" folder and happily use the machine for a few days with no problems. Then work off the battery voltage, put the PC in sleep for some time. When I try and log back in after the awakening of the PC, it does not recognize the password. Try with cap locks, off and all the rest, but not luck. I must finally remove the battery and restart. Sign in as normal (the password is recognized) and go in the user administrator account to disable the password, but then again, the current password is not recognized and I am not allowed to make changes. However, I can still close and log on by using the current password. Confused. Anyine have any ideas?

    There is no need to remove the battery or pull the taken when force a PC to stop. By pressing the power button for about ten seconds will do the trick.

    Your password problem: you might be dealing with a foreign keyboard problem. Make the password to something that is independent of the keyboard configuration, for example 123456.

    To reset the administrator password, follow these steps:
    1. click on start.
    2. type the three letters cmd in the search box.
    3. press on Ctrl + Shift + Enter
    4. click on "run as Administrator".
    5. type the following commands and press ENTER after each:
    net localgroup administrators
    (This will show you the accounts that have administrative privileges. What is?)
    NET user administrator 123456
    (This will set the password to 123456)
