Most hardware problems with the computer can be fixed without calling a PC repairman. But a PC is after all a piece of electrical equipment and can get damaged even if minor hardware problems are not looked after.
Some of the most common hardware problems that affect computers and their solutions are given below.
Blank monitors are among the most common computer problems. Most people who have computers will have dealt with non-working blank monitor at least once. The first thing to do is to check the supply cord and power systems. Sometimes, the video cable may be loosened. In this case, push the video cable into place again. If you can access another monitor, connect it to the CPU and see if it works. If it does, the problem is in the monitor or its wire.
Sometimes the monitor may display strange colors. Make sure that all the pins are properly secured on the CPU.
Hard drive is dead
A dead hard drive is a major hardware problem because it usually involves considerable expenses. The only possible thing you can do is to try and recover as much data as you can from the hard drive. There are specialized software available that can do this. Alternatively, you can also take it to a hard drive recovery expert.
Error when booting
Errors on boot usually happen during reboots. Some error messages will be self-explanatory but others may be technical. Make sure that all the wires that lead to the computer are properly pushed in. Sometimes, floppy disks and external hard drives can also cause error problems. Remove them and try to reboot.
If you are unable to start your computer, the best thing to do then is to restart the system and choose an existing configuration like Safe Mode or Last known Stable Configuration. The Safe Mode is the best option to choose because it will give the computer a chance to analyze the problem as well as adjust to new settings.
It can happen that the computer shuts down suddenly or it takes a long time to shut down. If you are facing these situations, it is best to look into the problem deeply. There may be a serious and bigger problem involved than just the computer shutting down.
It has been seen that excess heat can cause the computer to freeze and even lock up. The internal temperature of the computer is controlled by a fan. This fan is prone to accumulating dust and will not cool the system properly when it does. Removing this dust can work wonders. In fact, this is one of the first things you must do before you decide to buy a new heat sink or a fan. If the system still hangs, cut the load on the hard drive and the CPU. You can do this by stopping applications you don’t need (go to the task manager to find out which are the applications).
