How to Repair Canon EF-S 18-55 Lens Auto Focus

How to Repair Canon EF-S 18-55 Lens Auto Focus

In this tutorial I'll be showing you how you can disassemble your Canon EF-S 18-55 Lens and fix the Auto Focus problem. If your auto focus does not work, and you have tried the focus ring pull method, and your focus still does not work, then most probably one or more of your gears are stripped. 

To confirm if the problem is one of the gears, listen to the lens while pressing the shutter button to focus, if your lens makes a grinding kinda noise, then you need to change the gears. 

In this tutorial, I'll be showing you how to get in the lens and change either the stripped gears or the complete gear module.

How To Fix : Blue Scnreen of Death (BSOD) 7E in HIDCLASS.SYS While Installing Windows 7

How To Fix : Blue Scnreen of Death (BSOD) 7E in HIDCLASS.SYS While Installing Windows 7

I came across a new problem while installing Windows 7, while the installation was going on, in the middle of it all. I kept getting a blue screen. Of course if you're not going to see exactly what the Blue Screen is telling you, you'll just keep rebooting the computer and try re-installing the windows over and over again, resulting in a re-install loop.

According to the Pic belo ( HIDCLASS.SYS ) is the driver that failed. HID Means Human Interface Device, it could be a keyboard or a mouse.

Errors in HIDCLASS.SYS, especially during setup, majority of the times means that the trouble is with one of the attached Keyboard or a Mouse. Keep in mind that this also majority happens if you have a Wireless Keyboard or Mouse, so if you do have any of it connected, Simply remove it and try the installation again, and you should not have any issues now.

How to Fix: The Network Folder Specified Is Currently mapped Using a Different User Name and Password

The Network Folder Specified Is Currently mapped Using a Different Username and Password.

Symptoms :

Consider the following scenario:

* You have a Windows-Based computer that is running Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Or Windows Vista

* There are two network shares on a remote server

* You use user credentials to connect to one of the network shares. Then, you try to use different user credentials to connect to the other network share.

In this scenario, you may receive the following error message:

* The network folder specified is currently mapped using a different username and password. To connect using username and password, first disconnect any existing mappings to this network share.

If you click OK in response to this error message. 

Multiple connections to a server or shared resource by the same user, using more than one username, are not  allowed.

Disconnect all previous connections to the server or shared resource and try again

There are two Methods to solve this problem. Please see below :

Solution 1:

use the IP address of the remote server when you try to connect to the network share.

Solution 2:

Create a different Domain Name System (DNS) alias for the remote server, and then use this alias to connect to the network share:

After you use one of these methods, you can use different user credentials to connect to the network share. In this situation the computer behaves as if it is connecting to a different server.
