Fix your computer woes

Computer failures can cause a huge inconvenience for anyone relying on their PC for day to day tasks. In this article I will give you a few steps to narrow down the reason why your computer will not power up.

Instructions

1. One of the first things you must do is to determine if your power supply is faulty or not. If your computers power supply fan from does not operate when you hit the switch, you may have a faulty power supply or switch.

2. You can check the switch by jumping the two wires for a half second in order to mimic the action of the bush button switch. If the computer turns on, then replace the switch. If nothing happens then unplug any hardware from the power supply.

3. After unplugging all the hardware connect to the power supply, check and see if it will power up, if not replace, if it does then turn off the power supply and reconnect the motherboard ; proceed to test again. If the motherboard prevents the operation of the power supply then you may have an issue with your motherboard, processor or installed memory. You can try removing these and re-powering to rule out the different components.

4. Common hardware failures can cause your computer not to POST (power on self test) or "beep". Many modern motherboard manufactures will provide notification of hardware failures through beep sequences. You should check your motherboards manufactures manual to find out what the codes mean. You may have to search the internet or visit the motherboards manufactures website to get the original manual in electronic form.

5. If you do not know what specific brand of motherboard your computer has, you can check the motherboard for distinct numbers and words. Put those in to your browser to perform a search for information. Alternatively, if you have a common name brand computer such as a Dell or HP, you can usually find out this information quite easily as well as specific troubleshooting tips for your computer.
