My PC works very badly

Slow, my keyboard does not work half the time. I tried to disable frag, disk cleanup, remove the old files. Nothing works. It's really bad. It is a windows Vista, who said that half of my GB 139 original still. I need of more memory, or am I missing something all together?

You ask if you need more RAM, but could not say how many you have.  I'm afraid that my crystal ball could not tell me either.  :-)  If you have less than 3 GB, add more RAM will definitely help.  You must also run MSCONFIG and check to see what is loaded at startup.  Click Start and type MSCONFIG in the search box, and then click on MSCONFIG. EXE in the list programs.  Click the Startup tab and disable everything except your antivirus program, and then restart.

Here are some other things you can check. Get your updated antivirus program and start safe mode.  Note that some viruses can hide from your normal antivirus program, so you really need to scan mode without failure.  To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode.   Then run a complete system scan.

If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem.  To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore.  Click on the box that says show more restore points.

You can check the corrupted system files.  Open an administrator command prompt and run SFC if the above does not help. Click START, and then type sfc in the search box, right-click to SFC. EXE, then click on run as administrator. Then from the command prompt, type sfc/scannow.

Finally if all else fails, you can look at the rather cryptic system event log.  To make, click Start-> Control Panel-> administration-> event viewer tools.  Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

I hope this helps.  Good luck.

  • Ethernet cable to connect my windows laptop 7 to the internet. connection is very bad. It works but only for 30 minutes max.

    My internet does not work correctly. I use an ethernet cable to connect my laptop (using windows 7) to the internet. However the connection is very bad. Sometimes it works but only for 30 minutes max, and other times it does not at all, connect saying that the cable is disconnected. I tried 3 different cables to 2 different ports, then maybe the problem comes from my laptop. It connects to the wifi networks fine but not with the cable. Does anyone have any suggestions as to what could be the problem and how can I solve this problem?

  • One of my computers works very well to display my beneficiaries of my bank online and the other computer says that I don't have any beneficiary, worm 35 on both.

    Everything on my online banking Web site works fine except the display of my beneficiaries. It does not, he tells me that I don't have any beneficiary. This function works very well on my backup computer with 16, 32, and 35 versions.

    That's what my Bank said:
    There was some problems with the compatibility of Firefox to view online recipients. Please, try the following steps to clear the cache and delete cookies. If there is still a problem, start Firefox in Mode safe. While you are in safe mode, press the < Alt > or < F10 > to display the toolbar. Then select Tools > Options > advanced > general. Find and stop using hardware acceleration.

    Boot in safe mode to fix the problem, but it's a bit of a pain. A refreshment or a reset seems a little drastic and I would like to know what exactly is the problem before using the shotgun approach.

    Thank you

    Thanks for the replies. I have try to disable hardware acceleration, but probably no connect fees. My only add-on is edge of adblock and I disabled it for the site. The thing is, I don't want to disable either of these elements. I'll just start firefox in safe mode, if I need to access my beneficiaries. I was hoping that someone may know something that is bad in my profile that has carried over from previous versions or another kind of corruption. It seems strange that an entire site could work very well with hardware acceleration, but not to this one point.

  • iTunes movies Streaming gets interrupted from time to time... very bad movies

    Since I switched to AppleV 4th generation, downloaded movies get interrupted frequently during playback. I have uploaded a local NAS, who has always worked in the past and the stream via WiFi or Ethernet (tried both, same result).

    It started with Apollo 13, that I had long conversations with the iTunes Store support on. They have money back and asked me to re-download, but the same "stutters" occur, sometimes for a second, sometimes for 10 seconds or more, make films very bad.

    iTunes Store support sent to the AppleTV support and I've read that others have reported the same or similar behavior.

    Am running 9.1 tvOS (just updated today, in fact, so do not know if the behavior above has been fixed to 9.1). Model AppleTV is A1625 (64 GB).

    I should add that the same movies work well when directly looked on a Mac, it seems that streaming to the AppleTV is the problem somehow...

  • How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can?

    Switch issues. Help, please.

    How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can? We already checked the firewall as a question, that it was not, and now, we are puzzled.

    Well, I know that the issue is long-term... believe me, it's a long, but as they say, the devil is in the details. Anywho, the question is, my grandfather has a HP laptop, which for two years has been able to run through a Linksys switch to his router and connect its printers to his laptop. About two months ago it suddenly doesn't work like that. Now, it works fine if it plugs directly into the router/Ethernet. My uncle suggested that the switch was bad, but after testing the same port, cable and all, the switch worked well for him. ' GRAMPS really needs this answered, but someone else, it is called can not understand and now I, in turn, ask you all for what you can offer. Here are the ideas that we have already discredited.

    -Switch bad: as above, is that this particular laptop, even under identical conditions, the works of my uncle very well.
    -Bad NIC: debunked through the fact we connected to the computer directly to the router and it worked fine.
    -Bad configuration of the firewall: we have disabled the firewall (please do not notice, he wasn't the smartest idea, we already know) and even if she recorded the switch exists, the internet is always triggered when you are connected with the switch.

    Thanks in advance for any assistance that you can provide and Merry Christmas to you all.

    It would be useful to consult the results of the ipconfig/all command both when it is connected to the switch and when it is connected directly to the router.  In addition, what is the model of the switch?

    To save the manual copy and the new hits of the ipconfig/all command output-

    First connect through switch.
    Open a command prompt window (start > run > cmd > OK)
    Type the following lines in the black command prompt window and press ENTER after each line

    echo "Connected via the button" > "% UserProfile%\Desktop\ipinfo.txt".
    ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".

    Now connect directly to the router, type the following lines in the command prompt window and press ENTER after each line

    echo "Connected to the router" > "% UserProfile%\Desktop\ipinfo.txt".
    ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".
    Notepad '% UserProfile%\Desktop\ipinfo.txt '.
    output

    Copy the contents of the Notepad window in your response (if you use the laptop when it is connected directly to the router) or close the Notepad window, and then copy ipinfo.txt of the laptop to the Gramps in a USB FlashDrive you can connect to any computer allows you to answer.

    You can delete ipinfo.txt on the desktop when you are finished.

  • Login Creditials fail for desktop connection remotely using IP local. Connection via the hostname works very well in local intranet

    Something happened that broke my remote desktop connection.

    System-Win 7 Pro, with enabled Remote Desktop connections. (Static IP, router configured for port before any RDP to this system)

    For a few years now, I had access to this system via desktop remote with all the problems. I have connected by using the name of the computer on the local network and have also connected using the public IP address with a problem. Name of user and password for one, way worked fine.

    The other day there was a power outage or something, most of my systems was suddenly restarted or turned off, and my router had to be reset. Not sure if this is a coincidence of bad, but now the problem is that connection via the public IP address I get "your credentials did not work" when you try to connect. However, if I connect using the host name within the local chapter of the network of the same name to username/password work very well because they always have.

    That's happened. I'm going crazy trying to figure this out. My remote user cannot log on this system.  Help, please!

    Thank you for taking the time to answer, it's really appreciated. I could solve the problem. I don't know how, but if finally started working again. I have reset my network card and reset IP address static of the machine, that I tried to connect. And after some back and forth with that, all of a sudden he was still working. I was suspicious that my router was causing the trouble because the login failure was due to the fact that I've been routed to another computer, even if the rules of the if correct port forwarding. I just he blamed on the PC from Gremlins. I'll keep this info for future use. Some how all refreshed and began to work again properly.

  • My docs to Word that I converted in PDF used to be beautiful - now they look terrible.  The resolution is very bad and the type is difficult to read.

    The resolution on my PDF documents looks terrible.  The fonts are hard to read and have very low resolution.  That's happened?  I downloaded the most recent Adobe Reader because someone sent me a document to sign and he said: I needed the latest version, but everything changed when I downloaded this new version.  How can we get the old version or is there some secret to have my PDFs look away, they used to using the new version?

    I do a lot of training and use PDF MUCH files and these documents really look bad now.  Can you help me?  Do I have to download a previous version? How can I do?

    Note that this answer is ONLY a WORKAROUND for a very serious problem.  The real problem is that the latest version of Adobe Reader is unusable.  So I start a new thread with the title "the latest version of Adobe Reader is unusable".

    I use a desktop Windows 7 computer, and I had the same problem.  Yesterday I updated my Adobe Reader software, and all PDFs look absolutely atrocious with the new player - in the same way that you describe.  My eyes water when I try to read them!  It's not the files - it is the new player, because they are all files that were perfect with the old version.

    I am a professional computer, so instead of panic (the new version is completely unusable!) I searched on the website of Adobe and found a way to download the installation for earlier versions files. Try this link - it could still be good:

    https://get.Adobe.com/reader/otherversions/

    Select the options that you need (operating system, version, language) and give it a go.

    You will need to uninstall your current version (use Control Panel configuration/programs and features), because the installer will not install an older version over a newer version.

    I am running Adobe Reader X version 10.1.4 and it works very well.  God help us all when we are forced to update a day due to problems of compatibility with future versions of pdf!

  • Overview of very bad police on iPad retina (SE CC)

    Sorry everyone, I have a small problem: I created a page in 1024 x 768 with a font to 18pt and preview on iPad retina is very bad (great on iPad 1/2).

    I need to work on an application SE for all the iPad - what do I do? PDF article? Or what?

    NB: can I built one single App HD 2048 x 1536 edition?

    Also SE Creative Cloud Edition?

    I ask this question because I know that SE Creative Cloud Edition are minor features SE standard (ex: Analytics).

    Thank you!

    If get you an overview through the decorative Panel, it will create a folio hatched. Maybe that's the problem.

    I would suggest the creation of a folio, make sure that it is the 'PDF' format, and then add the article, then use "Folio Preview" from the Folio Builder Panel.

  • SVE14123CNB with camera of 64-bit windows 8 is to give a very bad image quality.

    My sony vaio SVE14123CNB with camera of 64-bit windows 8 is to give a very bad image quality.

    I have compained several times to sony, but they said that there is problem with windows 8 and this laptop model.

    I think that this response is not the solution to the problem, as it is my work that still hinder once. This laptop has with exmor HD webcam, so we expect the quality of the picture from the webcam to be strong, but it is dark, blurry, vary hard to identify someone even. It is even lower than some old VGA cam.

    Please provide a rigid solution.

    Hello krishna_18,

    The most common cause of this problem is a poorly lit room.  Please try to use the camera in well-lit areas.  Since there is no light or flash on the camera device, it is not able to work as well in dark situations.

    As to the answer before someone gave you "problem with Windows 8";  What they probably meant is that this laptop does not come with any software the camera included.  Therefore, the "Camera" app Windows 8 is what is natively provided and used.  This application is very limited in options and resolution.  Using an alternative app camera of your choice can also improve options, parameters, and results.
