A technician is troubleshooting a 4-year-old computer that takes a long time to boot, and identifies that the BIOS rediscovers all the hardware at every boot. What action would fix this problem?

• Replace the CMOS battery.
• Launch Device Manager to discover new hardware.
• Reset the BIOS using the CMOS jumper.
• Start the computer with the last known good configuration.
  

  Explanation: The CMOS battery helps the BIOS to keep the discovered hardware as non-volatile information. The Device Manager will discover new hardware in the operating system. Resetting the BIOS using the CMOS jumper will erase the stored information about the hardware found. The last known good configuration is used to restore the operating system to the last working state.
