Question about Computers & Internet
If your computer does absolutely nothing when you power it up - the fans don't turn on, no lights turn on and the the monitor screen stays dark, some component inside your personal computer has failed. Unfortunately, there are no visible fuses that you can replace. There's a good chance the power supply has failed however you need a PC power supply tester to test it. However, there are other components in your computer which could have failed and cause the computer to do nothing when you power it up. If you have the required tools, test equipment and understand how these components work you can test them and determined which component has failed. Otherwise, you need to have a computer technician determine what your problem is.
I'm sorry that I can't help you more, but repairing computers is similar to repairing automobiles . If my car will "turn over" when I turn the key on but will not start, I could replace the fuel filter, fuel pump, coil, ignition computer etc. until I found the problem, but I don't have the parts/tools, I don't know how to test automotive problems and I don't want to waste money and possibly cause more damage by just guessing. I take the car to my mechanic for repair.

Change the power supply if that doesnt fix it then your motherboard has blown, there are no fuses in the power supply, you have probably blown diodes inside it. You have tried another power lead, that you know is working?
