• General failure on Ping and TraceRT by WAN IP for 15 minutes after startup

  My Windows 7 64 of Profession will expose this problem.

  After startup, it cannot access anything whatsoever outside the local network.  I can ping, DRC and usually access anything whatsoever on the local network, including the router.  But trying to access what anyone outside the LAN does not work.

  Ping Returns the Timeout on the first response, and then general of failure for the other three.

  Tracert immediately returns a general failure

  I am ping IP address, no domain name, is not a DNS problem.

  After 15 minutes or, the problem resolves, and starting the machine works fine.

  Occasionally (once a day or more), it will return to the problem of General failure for 15 minutes, then return to normal.

  The problem does not occur in safe mode with network.

  The problem occurs whether the user is logged on the machine.

  I have disabled the Windows Firewall to try to resolve, without success.

  I also installed McAfee.

  Thanks for any help that anyone can provide.

  I would start by removing McAfee and using MSE at least to test.  You can not just disable McAfee, it should be removed and he is known for this type of problem.

  McAffe often contributes to BSOD

  
  

  I remove and replace it with Microsoft Security Essentials

  3 month old Dell inspiron windows 7

  impeccable wireless on old laptop

  Dell drivers and Utilities disc is weird... not me explainatory

  Most laptops have a button On / Off to toggle the wireless connectivity to security purposes. Dell Inspiron are usually Fn + F2 (noted with a little blue on the F2 key). Try typing this key combination to see if your wireless network can easily be reinstated.

  Fn + F2 is not correct, the other possibilities for a Dell would be Fn + F8 or Fn + F12. Look for the blue identification icon.

• Wireless network cannot connect after sleep (X 200 tablet, win7)

  Hi all

  I've seen similar problems like this asked several times, but they have rarely been resolved and not by any means that I have not already tried, therefore this is.

  Immediately after starting, my wireless card works fine.  After that I put my computer to sleep then wake up, however, the wireless network adapter seems to fail.  It still detects networks, but when I try to log in, it takes a long time to connect, then says he can't.  If I wait a bit and try again, the same thing happens.

  This can be solved temporarily by one of these three methods:

  1 restart the computer.

  2 troubleshooting wireless network card (it resets the adapter each time and then it works).

  3. go to network and sharing Center-> adapter settings-> turn off, then turn on the wireless card.

  This problem is reproducible on EVERY sleep and on ANY wireless network (i.e. it is not a router problem).

  Solutions proposed that I already tried:

  1 reinstall/restore/update driver software.

  2. change the settings for the network adapter power management to not allow the computer to turn off the device to save energy.

  3. change the power management not to go in network adapter power saving mode.

  Entails disadvantages because I often need to turn my computer on sleep and access to the internet, and disabling + to reactivate the wireless network card takes time.  If someone managed to overcome a similar problem?

  Thank you.

  Hey ez910503,

  You can try to uninstall the software of dial-up connection and wireless drivers.

  Let windows install its generic wifi drivers and try again.

  curious to know what is the current version of the driver that you are using for your wifi card?

• Windows Vista (64-bit) crashes a few minutes after startup is complete. Difficult to get out of the lock start.

  After a Windows updated 12/09/2009 from my computer stopped working.  It starts (without error) and then freeze a few minutes after loading Windows.

  I removed all the updates of Windows since mid-November, but this has not fixed the problem.  I also tried to boot to the last known successful configuration and has followed the procedures of "clean boot upward" found elsewhere on this forum.  None of these actions resulted in necessary corrections.

  Any other ideas?

• HP Pavilion notebook - audio maintains disappear minutes after pc startup

  Hello everyone. This is my first post in this forum.

  For about a month, I had an annoying problem with my laptop audio. Quite often, when I turn on my pc, my audio disappears after a few minutes. Sometimes, there is no solid right from the start. The mute button doesn't work, because normally there is an orange light when you turn off the pc sound, although that does not happen again. Windows Media Player can only read formats such as mp4, avi etc with no sound in the background. However, it cannot open mp3 files at all (the error message). Videos on sites like youtube stop playing after a few seconds (although the buffer is still ongoing, and of course there is no sound).

  So, basically, there is no type of audio from the speaker (as his error, sound message, control the sounds etc...)

  I tried to plug in the headphones and external speakers, but not luck.  I've updated my audio driver, but it did not help.

  Moreover, when I run the audio control panel test, an error message appears that says "device currently being used by another application. Please close all applications that use the device and start again. »

  My laptop is quite new. It's a "HP Pavilion 15 - e070sl.

  All this is driving my crazy. It's really frustrating. Any suggestions would be greatly appreciated. Thank you.

• card network disappeared on each startup but starts working well after each reboot.

  My problem is as Fallows

  1.I start my pc (windows 8) (I close that crashed my pc a few hours ago)
  2.i given cable is now connected to the internet (x red mark).
  3.I check Network and Sharing Center there is no adapter. (convenience store said is a software or hardware problem)
  4 then I rebooted my pc.
  5. now the adapter works fine and net is connected.
  This hole is on every time.
  Help, please.
  Thank you.

  Hello

  Win 8 has a new feature called quick start. It can sometimes cause problems as you mentioned as well as others.

  The best way to know if the problem is to disable and see what happens.

  This feature works only when you make a STOP and then start.

  It is not perform a RESTART.

  Turn on or off...

  Go to the control panel... Power options, and then select choose the power what buttons on the left.

  Then select change settings that are currently unavailable near the top center of the screen...

  Lower on the window, uncheck the quick start.

  This may or may not help your problem, but is easy to check.

  If this solves the problem, you can analyze what is not supported correctly.

  The problem is probably related to drivers for your network adapter, but quick start will worsen the problem if they are not good.

  Hello

  1. when the question is is produced?

  Data recovery:

  1. slave of your hard drive in another computer and read/save your data out there.

  2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

  3 Alternatively, use Knoppix Live CD to recover data:

  http://www.Knopper.NET/Knoppix/index-en.html

  Download/save the file Knoppix Live CD ISO above.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  http://isorecorder.alexfeinman.com/isorecorder.htm

  Download the Vista software from the link above.

  After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

  Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

  Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1 in the boot order.

  Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

  When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

  Click on the icons of hard drive to open and to understand which drive is which.

  Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

  Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

  How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

  There is no Vista free download legal available.

  http://www.Compaq.com/country/cpq_support.html

  Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

  Normally, they do this for a cost of $ small.

  In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

  See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

  Normally, you have to press F10 or F11 at startup to start the recovery process...

  Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

  You can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

  They will tell you how to do this.

  Every computer manufacturer has their way of doing recovery disk/s.

  Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
  A good Vista DVD contains all versions of Vista.
  The product key determines which version of Vista is installed.

  There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

  If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

• Computer crashes to 2 or 3 minutes after startup, sometimes said "not genuine Windows".

  Hello!
  I have a Toshiba Satellite L750D. Windows 7.
  Everything works fine when there is 3 months, I bought the laptop.
  A few days ago, it started to happen:
  The computer starts correctly, Windows starts up, watch the user login screen. Everything works well so far.
  This desktop computer, runs Windows as usual. Two or three minutes later, it becomes terribly slow. So slow that just try to open Explorer takes like 5 minutes... Then the situation becomes unbearable, it's as if the computer crashes.
  Then I have to stop it manually (by pressing button On / Off for 5secs).
  In another time, share this problem, it appears at the bottom right of your desktop that the copy of Windows is not genuine.
  I know that it is authentic, I bought the laptop and I have activated Windows correctly. But hey, this is a minor issue and only happens 1/3 of the time I try to start the computer. The main problem is that Pseudo-gel of infinite of Windows.
  Start in Safe Mode does not change the problem at all. It starts well and like 3 minutes later, becomes terribly slow.
  I can solve the problem somehow (running antivirus, etc.) because I can't throw soft...
  Appreciate your comments on this issue,
  Best regards
  Joel Mollering

  Hello!
  Thank you for the comments, but since the computer is a Toshiba, it has a default System Configuration that allows me to restore the laptop in fabric, without having to start windows.
  I did, I lost a couple of files, but now everything is ok.

  Thank you

• AT100s Wi - Fi freeze a few minutes after startup

  The option check Wi - Fi freezes on "off" by its own. Basically it s turn off and freezing while I m using the Tablet somehow.

  Also the hardware buttons like volume + &-aren t working and the power button won t work unless I force close the Tablet pressing long on it.

  Set the default Android system back and factory settings and try again.
  Maybe the system is fucked up due to the installation of some 3rd party applications.

• Computer stops in 3-5 minutes after startup

  Boots, slowly, but eventually the boots completely.  Stop with no warning, no error message.  Windows restore does not, but Control Panel, Explorer open straight.  Both the monitor and CPU at the same time stop.  Starts in routine diagnostic Dell, but runs out of time before that anything can be verified.  All CP/power options are set to never.  Comp was woking OK, without recent changes / installs.  A few days before all this started OK ran Windows Security Essentials. Win XP SP3

  Appreciate any suggestions.

  Thanks to all - those of you who wanted to return to material/heat were ahead of me, but you were right.  Finally got down and dirty, the plastic part that holds the main processor heat sink clips had broken, allowing the heatsink for the CPU.

  A new heat sink retaining clip, a little fat and we are back in the business.   Thanks to all - help each comment.

• Satellite P300 PSPCCE: Atheros AR9281 wireless network adapter are not all networks

  I have a Satellite P300 PSPCCE with Atheros AR9281 wireless network.

  After a clean install of Windows 7, I can't see wireless networks, unless I connect an Ethernet cable to my wired network card.

  As soon as I take the cable on wireless networks disappear. This computer had Vista and it worked fine there. I tried latest drivers available from Toshiba, but that makes no difference.

  I have tried disabling the wireless and turn market as well with the FN and F8 key and switch on the front. I also tried to uninstall. But it's always the same.

  If someone has had this problem and is there a solution to this?

  Hi mate

  To be honest I never did experience even with a WiFi card and I have no idea why the LAN cable affects WLan card functionality, it makes no sense to me!

  First, I recommend that you check the settings of the router and reset if necessary
  In addition, you should go to the s for laptop BIOS settings and set its default value.
  Check the version of the BIOS if newest is available, then an update would be worth a try

  You use the Atheros Wlan configuration tool?
  If this is not the case, try this out!
  It s a configuration tool that could be used instead of owning windows wlan settings
