  • Computer is very slow and IE does not work all the time.

    I bought a computer from my old employeer.  He is doing all sorts of things, or should I say not to do all sorts of things.  It is very slow and IE does not work all the time.  They have questions arise and ask if the administrator oks things and other things like that.  It came with any disks.  I would like to wipe, clean and load a new disc, but I don't know where to find the disc or if I can do it.   Can someone please?


    Proceed as follows to contribute to these two questions. You can probably buy the disks of Vista machine to system or get
    the former employer to do it for you if necessary.

    Try these and it can also be a good idea to update your main drivers later. The General corruption can also play a
    role in this issue. And even the TCP/IP stack might need to be refreshed.

    What antivirus/antispyware/security products do you have on the machine? Be one you ALREADY had on this
    machine, including those you have uninstalled (they leave leftovers behind which can cause strange problems).

    If no joy there's something blocking perhaps.

    Start - All Programs - Accessories - System Tools - IE with no Addons - what works best?

    IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

    IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK

    Close and restart IE or IE with no addons

    not better?

    IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
    "(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.

    Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
    are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.

    Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
    are bad, but some can cause your question (toolbars are BHO).

  • My driver support does not work all the time, won't let me connect, keeps losing internet connection.

    * Original title: SUPPORT of the PILOTS LOSE INTERNET.

    My driver support does not work all the time, won't let me connect, keeps losing internet connection.

    What do you mean by "driver support?

    If you have installed one of these offers of support software driver, you have installed malware.  The vast majority of them no useful software and installing a lot of malware on your computer.

    The drivers are not the soft thing you should normally be updated.  I recommend the updated drivers only in the case of a problem that has to solve, and it's rare.

    Is the ONLY source, you should consider for driver updates or OEM support site.  Even those who sometimes go way overboard in trying to update the drivers.  The latest Dell systems are equipped with updated software that checks for new updates every day.   In most cases, drivers are rarely updated after the first year of a product.

  • Create shortcut folders does not work all the time?

    I needed to create multiple folders shortcut for a project that needs them often, and I just couldn't. Still, I remember in the past and one of them actually have on my desktop for my photos.

    It appeared that in folder trees if I right click on the folder you want, "create shortcut" Option did not show upward! the same with the folders on my desktop would be! If rich of this conclusion, I copied my "recalcitrant" folder on the desktop (had to cut short the copy because it was great!), but got a copy of it on my desk (with only what he had time can be fully copied!). Then right clicked on it and the shortcut option appeared! I re routed the path to the original on my D drive folder and it works well.
    Obviously something does not work as it should and I don't have to do all this, so I hope someone knows the answer to this problem. Maybe a stupid option that must be checked on somewhere...

    I don't know if this is your question or not because it should either work, or not at all. The first fix, here is a zip file which will certainly not hurt to try. It's my answer for those who have reported lately that the new folder option did not work in Win7 canned.

  • Satellite U200 - sound does not work after the installation of Win8.1

    Hello guys,.

    I have some old Satellite U200-165. I installed windows 8.1 Enterprise assessment successfully after that I changed the hard drive SSD, but the sound does not work. Windows showing that his work perfectly, but it does not come out.

    An advise please.

    Satellite U200 is a pretty old and not supported for Win8 or Win8.1 machine. I think that we have no report on this forum how this old piece of equipment works with Win8.

    If the sound card is properly installed, have you checked all the sound settings?
    I presume that the same problem is with a headset, right?

  • Satellite L655 - sound does not work on the new install of Windows 7 Pro x 64

    Howdy all,

    I bought a Newegg L655-S5111, which was on sale, put an SSD, and then installed a legitimate copy of Windows 7 Professional 64 - bit, I got from my current employer (I'm a computer scientist). I've updated to the latest revision of the BIOS (1.70), and I have all the updates installed Windows, all drivers installed, including the correct drivers Conexant HD Audio and ATI HDMI Audio. Unfortunately, the sound does not work. Sound works briefly during my first install of Windows 7, then I cut it up until I could get it set up with a helmet. When I disabled it, she had stopped working.

    This laptop is less than 3 weeks at this point, old and I get no audio on headphones or speakers, even if Windows displays clearly no problems with the drivers, they have the latest version on a new installation, and I can see the audio mixer game. The laptop built-in microphone captures sound as well. I think that's probably not a matter of the physical interconnection, but more likely a software problem, I just have trouble identifying where it is.

    I have also no related error message than any where in the case of newspapers.

  • My very old DELL does not start all the time. And when that happens, it doesn't look very good.

    Original title: Please help



    It seems that two things must happen... Three if you don't have good backups (it would be the first thing * if * you have not any outside of the machine.)

    (1) the material must be tested.  By restarting and pressing the combination of keys at the right time could test the hard/readers/speed control (CTRL + ALT + D, on a dell computer before starting at startup of Windows.)  For other tests - Dell probably put on a partition or sent a CD with the machine that allows you to perform a battery of tests on the... video, audio equipment, etc.

    (2) a restoration clean install a factory should probably be made * if * hardware testing are in agreement.  You could probably clean the machine by following the steps I'll give you - but knowing no more about the problem that we are so far... If that does not better... it's perception, or something so serious, that a clean install is probably the only real 'next step '.

    (And if the new facility does not solve it and analysis of material found nothing - that's the perception, or something (material) defective which is not be picked up).

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

    -Open a copy of Microsoft Internet Explorer.
    -Select TOOLS - Internet Options.
    -On the general tab in the section 'Temporary Internet files', follow these steps:
    -Click on 'Delete the Cookies' (click OK)
    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
    -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

    No sound after installing XP operating system. What to say man I searched here in the forum similar threads and it seems that it is a common problem.

    But you worry about don t; I think that I found the key ;)
    After installing win XP, you must update the latter State. Install all the patches and hotfixes provided by Microsoft. You must use the website to update Ms. The tool on this page checks the system and selects all necessary updates!

    Very important are the patches; KB888111 and KB835221
    These hotfixes must be installed before installing the sound card driver.

    The Realtek sound card driver can be downloaded from Toshiba or on the official website of Relatek page.

    By the way; It is very important to install drivers in the correct order. On the Toshiba page, you will find the installation instructions. So please follow the guidelines mentioned in this doc.


  • Deliver the sound does not work on the computer.

    So sometimes the sound on my computer works just simply. This problem occurred recently: after watching a few movies on the computer using a double headphone output (I was watching with my sister) it worked fine, no problem. A day or two later, I tried to watch a video (on headphones) and the left earphone wasn't working - no sound didn't go out. I figured out the headphones were very good, but it's the computer problem. He started to work again the next day, but then most problems - sometimes no sound at all. No speakers or the headphones. Ever since then, it's like Russian Roulette, sometimes it is sound, sometimes it does not. I just wish the best. I tried troubleshooting and he said that he could not detect any problems. I tried to it turn on and off again? Yes, several times.

    I'm desperate for help! Thanks in advance.


    If the computer has a separate sound card remove ALL power and then remove and reinstall
    the map. If it's built-in sound so either she developed a hardware problem or
    something interferes with him. If the device goes wrong it may be replaced if

    a separate device or it can be disabled in the BIOS or Device Manager and
    a card can be used OR a USB card sound.

    Check in the Device Manager - Sound - Driver tab - go to the site of the manufacturer of the audio device
    Download and install the latest driver.
