Troubleshooting Computer Problems
When you encounter a problem with your PC, stay calm and take time to determine the symptoms. Below are some steps which will help you to track down the problems:
- Check that everything is plugged into the right place: Sometimes you forget to plug some wire or other device which can cause the problem. You should check for any loose connections in your computer system.
- Make sure you have latest software installed: Sometimes device drivers can cause the problem if they are not updated so please make sure you have updated your system with latest software so that system become compatible.
- Malfunctioning USB Hub: If you have a USB hub, please disconnect it for few hours to see if it is the source of problem.
- Check your anti-virus software: Sometimes Anti virus software can cause the problems because of some corrupt file. You should check that your antivirus is running properly and is up to date.
- When all fails, you should call in a professional.
Poor Image Quality on Your Computer
Image quality should be sharp in order to view them correctly but due to some wrong computer monitor setting you get the poor images. Here is a way to rectify it:
- Change your screen resolution i.e. if your current screen resolution is 800 by 600 pixels then change it to the highest recommended picture quality.
- Right-click your computer’s Desktop and click Screen Resolution from the menu that appears. The Screen Resolution window will appear. This setting is part of the Control Panel in Windows 7 and can be accessed from the Control Panel as well.
- Click the Resolution drop-down to select a screen resolution that works best for you from the list. Windows 7 will automatically determine the best resolution based on your monitor and will indicate the recommendation with Recommend next to the recommended resolution.
- When you are done changing the screen’s resolution, click OK to save the changes. You may need to confirm the changes. If so, click Yes to continue.
*Note: If you are uncertain about which resolution to choose, click Apply instead of OK to view the changes. You will have 15 seconds to save the changes before the screen resolution reverts to its original state.
- Check the monitor’s video cable to see if it has some bent or missing pins. If pins are missing then you have to replace it.
New Hardware Doesn’t Work
If you have just installed a new piece of hardware on your computer system and it’s not working properly then please follow the following steps:
- You should read the manual of installing the hardware carefully and follow the instructions given.
- Make sure that hardware is hooked up properly into its place. Also check that the hardware is not loose and its connection to computer is tight and secure.
- Try installing and then reinstalling the hardware.
- Try to update the device driver for that particular hardware.
Internet Is Slow or Not Loading
Determine the type of problem
Determine the type of problem by checking to see if the problem is consistent over different web browsers. Other questions to check is trying to find out if certain websites are running slow while others are running properly? Does the Internet get slower during certain times of the day?
Disconnect and reconnect your Ethernet cable
Disconnect your Ethernet cable and reconnect it. Check to see if the problem is resolved. Also make sure that both ends of the Ethernet cable are plugged in correctly.
Try pinging a website
If you're having problems connecting to the internet, you should first make sure that you are really connected—most of the time you can open command prompt (hit the Windows key, type cmd, hit Enter) and type in a ping command like ping yahoo.com to see if you're getting any response.
Slow Response Times
Sometimes the problem isn't connecting to the internet, but slow response times while you're browsing—or maybe your browser is simply hanging. If you're using Internet Explorer, you can reset all your settings to fix problems; if you're using Firefox you can follow this guide to troubleshoot problems or just completely restore the default settings.
If the printer will not print, the first step is to determine the type of problem the printer is having. The two main problems you would experience would be a mechanical/electrical problem or a communication issue.
1. Many models have a built-in self test option which allows you to print a test page by holding down the feed button for a few seconds. The power button will begin to flash and a test page will print. If the printer self test fails, your problem is with the printer itself rather than the printer cable or computer. Should this occur, you should contact a technician.
2. If the printer self test prints, the next step is to have Windows print a test page. Click on Start, Settings, Printers, and right click on the icon of the printer with the problem. Select properties and press the Print Test Page button. If the test page fails to print, make sure the printer cable is firmly seated in both the computer and the printer. You should also check the ends of the printer cable to make sure that none of the prongs are bent. If the test print fails, or if the print consists of nonsense characters or a few characters printed over many pages, you need to uninstall then reinstall the drivers for your printer.
Paper feed problems and jams can often be resolved by using paper which conforms with the specifications provided by the printer manufacturer. On ink jet printers, the rubber rolls which pick up each sheet can sometimes become coated with paper residue which decreases the friction. Cleaning off the residue can sometimes solve paper feed problems.
