How can I remove the existing driver files to overcome (Code 39) USB drivers?

I am running Vista Home Premiun 32 and generally have few problems for about 18 months because my laptop came with the operating system installed.

Recently, my USB drivers do not work (as in the drivers of USB controller rather than the connected devices). Device displays the symbol of my USB controllers and gives code 39 error Manager, that's to say the drivers are install correctly, but Windows is unable to run. Windows can certainly find and identify devices.

Two things happened before that:
(1) I have receieved some windows updates.
(2) I installed a backup software which seems to have prevented windows start: I had to uninstall the software by using regedit via the command prompt, and then, everything seemed fine.

It may, however, have been a problem that has just reached the point of crisis, given that windows has grown more glitch with my wireless adapter built-in and now don't see any; I think it's connected via USB controllers.

I uninstalled and reinstalled the USB controllers. I even deleted the INF cache and repeated the process of re - install.

Now, I want to delete the files from the driver completely from the driver store. Existing files are old (modification dates are from the beginning of 2008, or even from 2006), and I want to force Windows to find entirely new software drivers. When I uninstall, I not give me the option to delete files. When I try to delete them manually, I find that I don't have the correct security permissions to do so. Windows doesn't let me change the permissions, simply showing the menus change with the buttons greyed out.

This problem is in danger of turning my laptop a doorstop; There, someone at - it a solution?

Thanks for any help,
Ackers

Hello

Code 39 means that the driver is corrupted or missing.

  • How can I remove the Photoshop Temp File for good? (PS CS 4)

    Hello

    I have a problem on my PC. Since this Saturday if gives me the error "could not complete because full discs...» »

    I have read every blog/forum and even called the call center of photoshop without any help...

    Some of the solutions I've tried are the following:

    -Deleted all my Temp files (as I normally do every week)

    -Defragment my hard drives (done weekly)

    -Deletion of all unused software

    -Bought and installed a new hard drive (1 TB) to use as storage for this Temp file

    -All cleared the Cache and Cookies on my Browser

    -Use of the memory of Photoshop to 70%

    -Uninstalled Photoshop (PC Shutdown) and then re-installed and the Temp file is always there and it is much bigger than before

    Basically, I tried everything I could.

    What happens is that this Photoshop Temp 12389772616 file (44.6 concerts and increasing) cannot be seen when Photoshop is active or running and can not be deleted under these circumstances. When Photoshop is closed, it disappears as well. I don't know what else to do about it. When I re - allocate what is called a virtual file/disk to another hard disk, Photoshop slows and crashes more... I was thinking of buying the new Photoshop CS 5, but I am now, NOT wanting to take the risk, but it has served me well for a year so far.

    : NB is there any way I can reduce the size of this file virtual (Temp) or completely remove?

    My PC Specs are:

    Processor - Dual Core (2.3 GHz)

    Operating system - Windows 7

    Hard disk space - 1 TB, 500 GB and 250 GB x 2 (space is not a problem)

    Graphics - 8800 G - Force (512 MB) with GPU (PCI Express)

    Can anyone please help me or guide me on how to this mess?

    Just to clarify; is your main disk Scratch, named in Edit > Preferences > Performance an internal drive? If so, what is available on this subject?

    Is between "ideal" recommended RAM allocation in Edit > Preferences > Performance ?

    File slow opening is perhaps due to the default printer. This is a known bug and has been reported several times in the forum.

    The solution, weird as it may seem, is to make a printer driver generic default printer. If you do not, you can download it here:

    You must physically delete (or rename) the preference files or, if you use the Alt, Ctrl, and shift, don't forget you get a confirmation dialog box.

    AVG has moved my files from Windows Installer in a vault because of a Trojan horse.  Have I not need these files, and how to restore it without the Trojan horse goes with them?

    If files are missing or it cannot repair them after running SFC, in most cases there is no need to do a full recovery of Windows, like the other poster advised you to do.

    Since XP from, you have the option to do a repair Installation to solve problems, thus keeping all of your programs, settings, and data intact.

  • How can I remove "the folder/Users/user/to/mygame doesn't exist." Terminal. Rises every time I launch Terminal.

    How can I remove "the folder/Users/user/to/mygame doesn't exist." Terminal. Rises every time I launch Terminal. I am a novice. Thank you very much.

    1. Please select from the menu bar Terminal

    ▹ terminal preferences... ▹ Profiles ▹ Shell

    If the run command box is checked, uncheck it or enter the command to run automatically (if any), each opening of a Terminal window. Note: this is not how you define a default shell.

    2. If step 1 does not resolve the problem, see below.

    Back up all data.

    Select

    New Shell command ▹

    in the Terminal menu bar. Uncheck the box marked

    Run the command inside a shell

    If it is enabled.

    Copy and paste the following line into the text box that appears, and then press return:

    /bin/mkdir disabled_shell_files

    Close the Terminal window that opens. Repeat with this line:

    /bin/mv .profile .bash_history .bash_profile .bashrc .inputrc disabled_shell_files

    History Shell and former initialization files will be saved in a directory named "disabled_shell_files" at the top level of your home directory. It is normal that some of these files do not exist, and therefore, you will get error "no file".

    Close the window and open a new test.

    You may already know that files with name starting in '. ' are not visible in the Finder by default. So, if you open the folder that you created in the Finder, it will appear as empty, even if it is not. If you need to recover a portion of the data in the files of the shell, use a shell such as nano-based text editor (1). Make sure that you're not recreating the problem. Otherwise, you can delete the folder.

    Hello

    Try the following and see if it helps.

    I suggest you perform a disk check and check if it helps.

    See the following steps:

    a. open the computer by clicking the Start button, click computer.

    b. click the drive you want to check, and then click Properties.

    c. click on the Tools tab and then, under error-checking, click Find now.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    d. to automatically repair problems with files and folders that the scan detects, select automatically fix file system errors. Otherwise, the disk check will be a problem, but not to fix them.

    e. to carry out a thorough, check select search for and attempt recovery of bad sectors. This analysis tries to find and repair physical errors on the disk itself, and it may take much longer to complete.

    f. to check for errors file and the physical errors, select both automatically fix errors in file system and search for and attempt recovery of bad sectors.

    g. click on start.

    Note: When running chkdsk on the drive hard if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data can be lost.

    Note: Make sure also that you have disconnected all external devices except the keyboard and mouse.

    Note: If you are always faced with the question then I suggest you to upgrade on the spot and check if it helps.

  • How can I remove the old Windows folder to a different drive?

    Original title: Old files Windows, Program Files, etc.

    I tried to use before Disk Cleanup and it worked, and I haven't run a complete installation.

    I'm having a problem now, this time, and I did a full install.  Disk Cleanup doesn't show any options to remove an old Windows as it did before.

    How can I remove the old Windows folder to a different drive?  I also try to remove the Program Files folder, as well as with an implementation since.

    It is showing an error message "I need to be in the Administrators group ~", and that TrustedInstaller is owner of the present.

    I have a question that "TrustedInstaller" has full authority on the file system, and 'Administrators' has limited access.

    I noticed that there are other three to make a total of four names of users who have all or nearly full access to the file system.

    Can it be fixed... it's pretty annoying to see this continue..., strictly through Windows Update.

    I look forward to your reply.

    Hi Ron,

    You can copy or move information (for example, text and pictures) between files and programs using temporary storage called the Clipboard. The Clipboard is not visible, so even if you use it to copy and paste information, you never actually see the Clipboard when you do this.

    The Clipboard contains a block of information at a time. Whenever you copy information to the Clipboard, the old contents of the Clipboard is replaced by the new information.

    When you shut down the computer everything is stuck in the memory of the Clipboard is cleared.

    Please click the below mentioned link to get an overview of the clip board memory.

  • How can I remove the file name of movies that I import from my camera?

    How can I remove the filename of movies that I import from my camera - the film shows the name of the file on the screen and then disappears slowly?  Using Win 7 Pro and Home premium 64-bit.   Thank you.

    Edition - shows only upward on one of the 2 computers I have / use.  Any movie file I import was that if camera, animation or imported from youtube.  All formats - slight differences in size, fonts and the location.

    Hi and thanks... Videos out of my camera I'm just drag and drop to the desktop.  They are avi - cam is a Canon about a year.  Others are .mov of 3D software I use - Cinema 4 d. I save animation software in the appropriate folder.   Youtube videos are made with YOutube Video Downloader and files are for most .flv but others come too.

    All of these files open when doubleclicked and the name of the file is very large print at the bottom of the screen may be 4 seconds then fades.  I've not edited somehow - they are the first "raw" video camera or animation software.

    It is not consistent, but especially it happens only on one machine - Win 7 Pro with all the updates.

    Thank you.

    ========================================
    I suspect the media player you use poster
    the file name. Check the properties/preferences of your
    Media player to see if you can change a setting.

    For example, VLC displays the name of the file... and you
    can go to... Tools / preferences / All / video...

    Scroll down to and uncheck 'Show Media title on Video'... / Save.

    The next time that VLC is started the video title should not be displayed.
