Windows XP Trouble Shooting Questions

Q: What to do with the issues that may pop up at the time of USB device installation?

A: You might face the problem of USB device installation in Windows, because of several devices, such as scanners, printers, modems, wireless adapters etc. there must be device driver software installed in the computer otherwise you will not be able to use it. You should always install the driver software before connecting the device with the computer but if you have accidently connected the USB device then you can follow these steps to get rid of problems:

1) Right-click on ‘my computer’ icon

2) Go to ‘properties’ and then you’ll see ‘Device Manager’, click on it.

If you are trying to play recent games then you will face problems in case your computer is older than 2 years, because the recent games are designed according to the new hardware configuration of the computer. You will need sometimes to decrease the game graphics so that it can fit the hardware capacity of the computer.

Q: What can you do if your Windows stops responding?

A: You should try to know the exact moment when your computer just stops responding, such as: if it happens often while your computer is at hard work (like at the time of playing games) then you should check the issues related to heat. The intake fan of your computer might have failed, or perhaps the vent might have been blocked. Also ensure that the heat sink of CPU is making good contact with the processor’s top part and you must also ensure that the fan of the CPU is clean. In case the problem happens randomly then scan your computer because there might be a virus behind all these problems. You should also check the driver software if they are up to date or not. If again the problem is still there then check the hardware, RAM of your computer or power supply might have problem.


Q: How can you raise the general performance of your Windows operating system?

A: In case your computer’s general performance is slow then maybe the basic maintenance can resolve this issue easily. First of all you should uninstall all the unnecessary programs which you don’t use any longer. Start the defragment process to all your disk drives regularly. Some programs like ‘helper’ are mainly used to launch the application quickly. Those are associated with this program and this ‘helper’ program runs in the background when you start the Windows. But if you don’t use those programs which are associated with the ‘helper’ program then it is necessary to uninstall it because it can ‘help’ in slowing down your computer. If you use only few and necessary programs then your computer will be with good performance, therefore, you should remove all the unused programs.

Reinstalling or removing the program

If you are having problems in operating the computer or some other programs after the installation of any new software then uninstall the software and note if the problem is still there. After this, start the installation process again and install the program. Sometimes Windows says to restart before using the new software installed and if you’re still opening the new program then you may face the problem, therefore, you should restart the computer before using that software.

You should check for the update version of the program that you are going to install in your computer. If you are going to install the driver software for printer or scanner or any hardware device then it is necessary to install the updated version of the driver software for the good and quick performance.


Q: Your computer’s programs stop responding, what can be the reasons?

A: Your computer’s operating system, driver software or some other programs may stop responding while using them or they can make other programs to stop running and there may be several reasons, like:  lack of proper system resources, confliction between two software or hardware resources, bug in the driver software.

If you are having the not responding problem then following solution will be helpful:

Generally, while any of the programs has stopped responding then ‘Task Manager’ can be opened in order to close the program. Press ‘Ctrl+Alt+Del’ on your computer’s keyboard to open the ‘Task Manager’ and select the program which has stopped responding. After that click on ‘End Task’, and then the program will be ended. Sometimes another window opens with the option ‘End Now’, if it shows up then you should click on ‘End Now’.

You will not be able to recover the unsaved work while running this process and unfortunately, there isn’t any option either.

If you are continuously having this problem of stop responding then it is recommended to run the troubleshooting program and that may be very helpful.

Q: When a Windows administrator has to disable one specific hardware device that is integrated in the motherboard, what method is the most appropriate?

A: There are two possible methods. The first will be applied by right clicking on the ‘My Computer’ Desktop icon and selecting Device Manager from Properties. This is a common thing to do for many Windows troubleshooting situations because it provides access to various details about the hardware components in the system, their driver configuration and other advanced features. The second solution is using the command ‘devmgmt.msc ’ from the command prompt.

Q: What happens in the case where Windows troubleshooting is necessary and the Help and Support Center doesn’t work, what services must be used then?

A: There are two options to use from the Help and Support Center. One is the Microsoft Help Center Service or Helspsvc.exe, the other one is the Help and Support Center executable or Helpctr.exe. Both options can be verified by opening the Task Manager.

Q: What happens when a Help Desk professional needs to offer assistance for troubleshooting to a remote user in a remote office, what Windows feature is useful in this case if the Help Desk professional doesn’t want to drive four hours to fix the problem?

A: In Windows XP, with the aid of Remote Assistance we can open a direct connection that links 2 computers through Internet or LAN. Regardless of the distance from which the operation is conducted, the user is able to see the on screen instructions and learn how to fix the problem on his/ her own. This includes using Control Panel, running diagnostics, editing the registry and making different updates.

If the computer from that address sends the response it means that the Internet connection is working.

Q: In the case when the administrator of a purely IP based network encounters connectivity problems, what command is used for displaying the connectivity problem and what command tools are used in Windows XP?
