Hands-on Project 13-3 Sabotage and Repair a Computer Open the computer case and create a hardware problem with your computer that prevents the system from booting without damaging a component. For example you can disconnect a data cable or power cable or loosen a DIMM in a memory slot. Close the computer case and restart the system. Describe the problem as a user would describe it who does not know much about computer hardware. Power down the system and fix the problem. Boot up the system and verify all is well.
