We have observed this problem at may places that you need some data on your pen drive but the USB drive or pen drive does not work. Windows gives a notification

“Found new hardware, USB Mass Storage Device, please install drivers for it.”

Windows will now show a New Hardware Wizard to install the drivers. Lets see in details how we can fix this problem.

Fix:

There are more than one ways in which the USB drives are disabled by Administrators at offices or colleges or schools. These methods are:

1. By Disabling USB Ports from Device Manager.

2. By Tweaking Registry values for USB Mass Storage Devices.

3. By Un-installing the USB Mass Storage Drivers.

We will see how to fix all these situations one by one. But before you begin, you must have administrator rights on that computer to fix the issue. If you don’t have the rights, see this post on getting admin rights on windows computer.

Lets go one by one for the solution now.

One of our readers Kapil reported that his computer has been infected with chost trojan. Because of this trojan certain web-sites are not opening. This kind of problem can also be caused by trojan.vundo .

Although this is a old known trojan, so your anti-virus software should have virus-definitions to take care of this trojan. But even if the anti-virus software has cleaned the trojan, the chances exist that you will still face problem in opening web-sites.

This is so because this trojan modifies your windows “hosts file” and makes certain web-sites point to a local host. Such web-sites will not load until this host files is corrected.

Let us see how take care of the trojan and fix the hosts file.

One of our readers Senthil wrote

“When I switch on the computer the following error will displayed : <windowsroot>\system32\hal.dll is missing or corrupt please reinstall the copy of above file”

What is hal.dll ?

Short for Hardware Abstraction Layer, HAL is an operating system programming layer that enables the operating system to operate with a hardware device. hal.dll is the dynamic link library file that implements the functionality of HAL.

When “hal.dll missing or corrupt” message appears, it can be because of damaged or missing hal.dll file. It can also be because of some wrong entries in boot.ini file in case you are using two operating systems on your computer. Also it can be because of improper BIOS entries of the disk drives etc.

Lets have a look on how this can be fixed.
