Common PC Troubleshooting Issues
Computers have become an integral part of the business world. Knowing how to troubleshoot is critical, as a PC that is not working can mean lost hours of work and even a loss of revenue.
-
Unplugged Cables
-
A common reason why your computer will not boot up or respond correctly is because something is unplugged. Check all connections, starting with the power cord.
Program Freezes
-
There are many reasons an application can hang up or crash. Sometimes a file can get corrupted or a process can be caught in a loop. Try solving this by restarting the program.
Loss of Internet Connection
-
Another common issue that occurs is a loss of network connectivity. If you are using an Ethernet connection, be sure that the network cable is securely plugged in on both ends. If using wireless, make sure your wireless card is turned on and check the wireless router. The problem could also be with your Internet provider, so it is a good idea to call them.
Mouse Failure
-
An optical mouse must be on a dark, non-reflective, smooth surface to work properly. A trackball mouse can get gummed up with dirt. Open the trackball plate at the bottom, remove the ball and clean the trackball and the rollers inside the mouse with rubbing alcohol.
No Sound
-
If the speakers are using an external power source, make sure they are plugged in and turned on. Also be sure the speakers are plugged into the proper port. On most computers, this is denoted by a green-colored port.
