1. A web designer installed the latest video editing software and now notices that when the application loads, it responds slowly. Also the hard disk LED is constantly flashing when the application is in use. What is a solution to solve the performance problem?

  • replacing the hard disk with a faster model
  • upgrading to a faster CPU
  • replacing the video card with a model that has a DVI output
  • adding more RAM*

Explanation: RAM problems are often caused by faulty RAM modules, loosely seated modules, an inadequate amount of RAM, and compatibility issues. When there is not enough RAM in the computer, data needs to be swapped often between the RAM and the hard disk (indicated by hard disk LED constantly flashing), which significantly slows down data access speeds.

2. An employee reports that each time a workstation is started it locks up after about 5 minutes of use. What is the most likely cause of the problem?

  • The hard disk is failing.
  • The RAM is malfunctioning.
  • The CPU is overheating.*
  • The power supply fails to provide adequate voltage and current.

Explanation: Processor problems are often caused by faulty installations, incorrect CMOS setup, inadequate cooling and ventilation, and BIOS compatibility issues.

3. 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.

4. A user has noticed that the hard drive LED on the front of the computer has stopped working. However, the computer seems to be functioning normally. What is the most likely cause of the problem?

  • The hard drive data cable is malfunctioning.
  • The motherboard BIOS needs to be updated.
  • The hard drive LED cable has come loose from the motherboard.*
  • The power supply is not providing enough voltage to the motherboard.

Explanation: Each light on the front of the case is powered by the motherboard through a cable that attaches somewhere on the board. If this cable comes loose, a particular light on the front of the case will not work.

5. During the troubleshooting of a PC that will not boot, it is suspected that the problem is with the RAM modules. The RAM modules are removed and put into another PC, which successfully powers on. The RAM modules are then put back into the original PC and it now successfully powers on as well. What was the most likely cause of the problem?

  • The RAM modules have bad blocks.
  • The RAM modules were not seated firmly.*
  • The RAM modules did not match the PC specs.
  • The RAM modules were inserted backwards into the DIMM slots.

Explanation: If RAM is not seated firmly in the motherboard DIMM slots, it will not function properly. RAM cannot be inserted backwards into a DIMM slot because both the RAM chip and the slot are keyed so they only fit one way.

6. What component is most suspect if a burning electronics smell is evident?

  • CPU
  • hard drive
  • RAM module
  • power supply*

Explanation: A burning electronics smell is often detected when a power supply is overloaded and damaged.
