PC’s can develop mysterious ailments suddenly. However, if you know what you are looking for you can quickly solve the problem. The key to this is isolating the issue.
Usually, if it is a hardware related problem, you can identify it through the Power On Self Test (POST) beeps. These beeps will help direct you in the general direction of the problem. The common reasons are Memory, Video Card, Keyboard and Motherboard issues. However, there are times when the beep can’t help you.
At times like this you should know that there is an in-built mechanism in motherboards designed to protect the system from overheating. Reboots are triggered to avoid the overheating issue. Sometimes an improperly installed CPU or cooling systems can result in extreme overheating. Check you PC for these issues and rectify them.
Another cause for reboots could be RAM based. Improperly seated RAM or busted RAM chips will cause errors. To rectify this, remove all the RAM chips and insert them one by one and check the machine. You should also alternate the slots they were originally in to determine if there is a problem with the slot itself.
Capacitors can also be a problem point. When you are inspecting your motherboard for faulty capacitors, look out for puffiness or leakage. Capacitors have pattern on top that resembles an X or a cross and this area should look flat. If it looks raised or puffed, then it is an indication that it is faulty. Do not try to replace capacitors on your own unless you have a good deal of electronics knowledge. Capacitor issues usually mean that you need a new motherboard; unless you know a good electronics repair shop that can do the job properly for you.
