Just follow the steps below to hopefully bring your Computer back to life.

The first thing you should do is check the power supply just to be sure that there is power available for your computer. Make sure the power switch is turned on and then try to plug a lamp in the wall socket to see if it works. If it does, you know there is power available. Once you know there is power, check to make sure the power cord is properly connected to the wall outlet and the computer power socket.

Note: Before you continue on to the next step, make sure your computer is completely shut down and be sure to disconnect it from the power cord as well. Also, keep in mind that all of your PC's components are sensitive to static electric charges, so it's important to ground yourself by touching the frame of your computer's case before starting any of the troubleshooting processes. This will get your body used to the computer case and eliminate any chance of static shock.

The next thing you can troubleshoot is if all of the cards within your computer are fully pushed in to their slots. Open your computer's system unit and push down on all the chips, the video card, the sound card, the modem or LAN cards, the memory cards and the CPU units to make sure everything is seated properly.

Now, check your computer again to see if you have been able to fix the problem. If not, keep troubleshooting! Next, check the power between the power supply you use and the motherboard on the back of your computer. If you need to, pull out and reinsert all of the cards. You can also try placing them in different slots until you find a perfect fit for all of them.

If you have not been able to resolve the issue, the next thing you can do is take out all non-essential parts from your computer, leaving only the basic ones in. The basic parts are the motherboard, the power supply, the display card, the controller and the hard drive. You can pull out everything else (mainly the other cards) by removing the screws from your unit, as shown in the screenshot below.

Now, replace each part that you took out one at a time until the problem reoccurs. When you replace a part and the computer stops working, you know that particular part is the reason for your computer problems. If this is the case, that part can just be replaced and your computer should then operate normally.

If you still see some issues, remove all of the remaining cards, including the display card and floppy controller. Then turn on the power just to see if the power supply is still running. If it does run, one of the cards you just removed is faulty. You will then need to get that one replaced.

These are just some simple techniques you can try to get your computer up and running again. Please use extreme caution when removing certain parts of your computer. If you are not completely sure on how to do it, get some help or take your computer to a repair shop so a professional can look at it. You don't want to risk creating other problems for your computer by doing an incorrect job.

Computer Repair Service Shop are charging so high nowadays. Some are charging 50 to 60 dollars per hour. So it's really a must to learn some Basic Computer Troubleshooting Techniques.
