At times it do happen that your computer may fail to turn on or boot to desktop even when it was properly shut down the last time it was used. This may turn out very frustrating. However, there are some effective ways to manage this problem whenever it rears its head. They are as follows.

WHEN COMPUTER DOES NOT POWER ON

1. Check the AC current if it is up to the normal AC rating in your country. Over here in Nigeria, check if the AC current is up to 230-240 Volts because that is the normal current in Nigeria. If that is the case, then that means it can power the computer.2. Check the power pack: If your power pack smells burnt, it means the power pack is blown. Some power pack has a switch that can switch to either 110 volts or 230 Volts. If that is how your power pack is, then switch it to your country’s current rating.

Next, ensure that the cmos jumper cap is in pin 1 and 2. Then power the computer. If it still does not come up,

3. Isolate system component: This means that you have to isolate the entire system component and reinstall them one after the other. Finally,

4. Check Processor: Uninstall the cooling fan and heat sink, insert the processor without the cooling fan and heat sink, them connect other component and power the computer. Place your hand on the processor to know if the processor is hot or cold if its cold that means the processor is bad, and vice versa. If the processor has gone bad, then the only option will be to replace it!

GOOD LUCK!
