Dead computers can be revived depnding on what's wrong with them.
If you start your computer and absolutely nothing happens, you might think your computer is dead. It might indeed be dead, but computers can be brought back to life. Fixing a dead computer is not just a matter of fixing one problem, however, because the computer can be "dead" for a number of reasons. Bringing the computer back might take several components being checked or replaced.
Instructions
1. Unplug the computer from the wall and the computer. Open the computer case door by unscrewing it from the back of the computer. Disconnect the power connections from the motherboard, the hard drives and anything else power connectors are connected to. Unscrew the power supply from the back of the computer. Remove the power supply and replace it with one as powerful as the original or more powerful. Connect everything back.
2. Replace the RAM. The current RAM will lift out of the slots if you pull back both tabs on the sides. Check your manual to be sure which RAM you can use.
3. Replace the motherboard and CPU. To replace the motherboard and CPU, you will have to unscrew and remove all of the cards, disconnect the drives, disconnect the power supply and then unscrew the motherboard from the computer. Screw the new motherboard in place and then reconnect the power supply, drives and cards. Put the RAM in from the old motherboard. Try putting the old CPU in the new motherboard, and if it doesn't work, replace the CPU.
