PC mouse problems seem to occur at the worse possible times. It's very frustrating to move your mouse only to realize nothing is happening on the screen. When an input device like a PC mouse stops working properly, the problem may be with the mouse, the computer, or even the operating system. A typical PC mouse will last for years with very few problems. When problems do occur, here are a few steps to help you identify and fix a PC mouse.

1. Shut down your computer, unplug the mouse.

2. Plug the mouse back in. The connector will either be USB or PS/2. A PS/2 connector is color-coded green and can only be inserted in one direction. Check for any bent or broken pins, then carefully plug it in making sure the connection is secure. Then start your computer and check if your mouse works fine.

3. You may connect problem mouse to another computer to verify that problem is with your mouse. Simply connect mouse to another PC, reboot it and check if it works or not.

4. Check for device conflicts. When you install another device on your computer it can sometimes cause conflicts with a PC mouse. Remove any new hardware and drivers you may have installed then reboot the computer.

5. Sometimes there is a possibility of mouse drivers conflict. It is recommended to reinstall drivers in this case. Open "Control Panel" then "System." Select the "Device Driver" tab then scroll to and select your mouse. Uninstall any drivers that are listed. Unplug the mouse then reboot the PC. Reboot the system again, plug the mouse back in, then allow Windows to reinstall the drivers if prompted.

Windows XP has built-in CD burning software. It's actually very easy, you simply need to perform a few actions. Follow the instructions described below in order to burn data into CD-R using Windows XP.

Method 1.

1. Right-click the file you want to copy, then select Send To, CD-R (or whatever your CD writer is called).

• You can use your CTRL key to select multiple files then send the whole mess to the CD burner.

When you do this Send To thing, you'll get a cute little "balloon" from your system tray telling you that the files have been added to your recording list. Click that little balloon and you'll open the list.

Method 2.

The next method is to open My Computer, then your CD-R or CD-RW drive. It's probably best not to have any CD in the drive at this point, since all the files on that CD will show up and make things a little confusing. Anyhow, just drag and drop (or copy / paste) the files you need to copy to the open window.

• Note that when you send, drag, or copy these files, it only puts them on a list, it doesn't automatically start making the CD.

2. OK, at this point you should have some files that have been sent to the CD burner. Now it's time to actually make your CD. Note that if you want to sound a bit more hip, you would say it was time to "cut" or "burn" the CD, but I digress.

So, stick a blank (writable) CD into your drive, open My Computer (if it isn't already), then double-click the CD-R/RW drive. You should see the list of files you've selected to record. Note that you may already be on this screen if you either did a Send To and clicked the balloon or if you did the drag & drop thing (since this was where you were dragging & dropping to).

Now, look for the CD Writing Tasks section. It should be at the top left of the screen.

Click the Write these files to CD link and it will start Windows CD burning wizard. From there, just follow the prompts.

• Note that if you accidentally stick a file on the list that you don't want on CD, you can remove it by right-clicking the file and selecting Delete. Don't worry, it won't delete the file from your computer, just from the CD writing list.
