Things You'll Need:
- Computer Tool Kits

Restart the computer. Many software problems will correct themselves when you do.

Check your cables. Keyboard not working? Make sure it's plugged in. Mouse not responding? Make sure it's plugged in.
- Step 3
Check the electric power. Plug a lamp into the same power outlet that's connected to your computer to make sure the outlet is working.
- Step 4
Make sure the computer and monitor are plugged in.
- Step 5
Disconnect peripheral devices (such as a printer or external Zip disk) and restart the computer.
- Step 6
Listen for unusual sounds. Is the cooling fan running? Is the hard drive making noises?
- Step 7
Look inside the computer for wires that aren't plugged in all the way or other faulty connections.
- Step 8
Start the computer from an external start-up disk, such as the system software CD that came with your computer.
