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 is turned on and then try to connect a lamp into the socket to see if it works. When it does, you know there is power available. When you know there is power, check the power cord is properly plugged into an outlet and computer socket.
Note: Before you proceed to the next step that your computer is completely closed and be sure to disconnect it from the pipeline
as well. Also remember that all your PC's components sensitive to static electrical charges, so it is important to ground yourself by touching the frame of the computer's case before any of the troubleshooting process. This will cause your body to the computer case and remove any chance of static shock.
The next thing to troubleshoot is when all the cards in your computer is fully pushed into their seats. Open your computer's central processing unit and push down on all chips, graphics card, sound card, modem or LAN card for memory cards and CPU units to make sure everything is correctly installed.
Now check your computer again to see if you have been able to solve the problem. If not, keep troubleshooting! Then check power between the power supply you use and the motherboard on the back of your computer. If you must, pull out and reinsert all the cards. You can also try placing them in different slots until you find one that fits perfectly with them all.
If you have not been able to solve the problem, the next thing you can do is take out all non-essential parts of your computer, so only the basic them in. The basic parts are the motherboard, power supply, the display card the controller and hard disk. You can pull off everything else (mostly the other cards), remove the screws from your device, as shown in the screenshot below.
Now replace every part that you took out one at a time until the problem reoccurs. When replacing a part, and the computer stops working, you know that a particular part is why your computer problems. If so, that part can simply be replaced and the computer will then function normally.
If you still see some problems, remove all the remaining cards, including graphics 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 defective. 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 you remove certain parts of your computer. If you're not quite sure how to do it, get help or take your computer to a repair shop, so a professional can look at it. You do not want to risk creating other problems for your computer by doing a wrong job.
