• Sometimes when I restart my laptop I get this message: "no operating system found".

  What should I do? I have only windows vista on my laptop and my system is clean and working properly.

  Why I not get that?

  After you receive this message, I press ctrl + alt + del then starts normally.

  Hello

  This problem may occur for a few reasons.
  (1) hard disk cannot be read sometimes... maybe there are errors on the disc that 'may' be fix by running a utility or two.
  (Open the computer and right click on the C drive and select Properties. Click on the Tools tab, and then click check now in the error-checking box.
  You can also use the tool to defrag as well. It takes some time so do it when you don't need to do much.
  You can also run the check disk from the command prompt. Click on START and type > order > press ENTER.
  Type > chkdsk C: /f > press enter

  Just a test to see if the problem happens again.

  2) there is an intermittent problem with your hard drive.
  Hard drive might be close to going out. You may need to get a new drive. You can make a backup of the system and restore to the new drive... IF that is the question.
  It could be the drive is simply 'loose' and needs to be reset. Should be just one or a few screws to remove the disc. Simply plug in the back and see if that was the issue.

  (3) the controller card has problems. It is bad on a laptop, because it would require a new motherboard... sending essentially to a store. If this would be probably covered under warranty.

  The first option would certainly test carefully. If that does not do it, make sure that the disc is properly seated to make usre is not easy like that.

  By all means, save all the files that you need to keep.

  I stopped to receive mail after December 31.  It indicates that the computer cannot connect to my account but when I log in with my password I get the message "this account already exists." How can I get my email account to work again?

  MacBook Air, OS X El Capitan

  First of all, make sure that you don't have two accounts with the same address. What happens if one of them is an iCloud account.

  From the Mail menu bar, you select

  ▹ Connection Doctor window

  In the window that opens, look for an SMTP (outgoing mail) account with a name that corresponds to the account that you are trying to add. Double-click it. Another window opens, displaying the list of all outgoing mail accounts. Click the sign button less to remove the corresponding one, and then click OK.

  Try to add the email account again. If you still can not, log off or restart the computer, and then open the preferences window accounts Internet and check if the account is displayed.

To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

  This is how the recovery partition is accessible to most popular brands...

  For Dell, press CTRL + F11 directly after switching on the device

  For HP, press F11 directly after switching on the device

  For LG, press F11 directly after switching on the device

  For Toshiba, press and hold "0" BEFORE and during the power upward

  For Acer, press and hold ALT + F10, as soon as you see the logo

  For Asus, press F9, as soon as you see the Asus logo.

  For Samsung, press F4 to the power upward...
