  • 12. Different BIOS setup’s Standard set – up : press <DEL> to enter setup- Date/Time, Setting for Floppy Drive A & B- Setting for Master HD & Slave HD Advanced Set – up :- Keyboard & display settings, Mouse set – up- System Boot-up NUM LOCK, System Boot Sequence- Floppy drive seek at boot & drive swapping- virus warning, CPU internal cache/External cache- Quick power on self test(POST)- Boot sequence- Swap FD, Boot up Floppy seek, Boot up NUM LOCK status- Boot up system speed- Gate A20 System Speed – (HMA) High memory area
  • 13.  Chipset set-up :- cache memory settings- Auto Configuration- DRAM cycle time selection- MA(Memory address) wait state- CPU to PCI IDE posting- System BIOS cacheable – F0000 – FFFFF-Video BIOS cacheable – C0000 to C0FFF-Video RAM cacheable- 8 bit and 16 bit I/O recovery time – delays- AGP Aperture (portion of PCI MA) Size (MB)- CPU warning temperature- Current chassis (RPM) for CPU FAN speed
  • 14.  Power management:- Enable/Disable (APM) Automatic Power managementMode- Sleep mode time out, Suspend mode time out-VGA Power down, HDD Power Down TOOLS
  • 15. CMOS/BIOS Errors The complementary metal oxidesemiconductor (CMOS) or non-volatile random access memory(NVRAM) stores the systemsstartup configurations andparameters. To access the CMOS setup utility,press the setup key during theboot process. The setup key must be pressedearly in the boot process, or thesystem will load the installed OS. The CMOS setup key is usuallyF1, F2, or Delete.
  • 16. CMOS/BIOS Errors Clearing the CMOS memory is usefulwhen the computer will not boot at all. The easiest way is to clear memory isto remove the CMOS battery.1. Turn off the power on the computer.2. Remove the CMOS battery from themotherboard.3. Short the negative and positiveconnections (terminals) of the batterylocation on the motherboard4. Replace the CMOS battery in itsoriginal position on the motherboard.5. Turn the power on (reboot) the system.
  • 17. Overview ofField Replaceable Units (FRUs
  • 18. CPUs CPUs must be set to receivethe correct voltages to runproperly. That use Socket 5, Socket 7 orSuper Socket 7 chips need touse voltage regulators. Typically, the voltageregulators are built into theboard. They must be set at theproper voltage, or the CPUcan be damaged. Staggered pin grid array
  • 19. RAM Some motherboards requirememory modules to beinstalled in a particular slotorder, or jumpers to be set(SIMMs, DIMMs, and RIMMs).
  • 20. Power Supply Issues The power supply convertsthe current coming from thewall jack from alternatingcurrent (AC) into directcurrent (DC). An onboard fan attached tomost power supplies cools thepower supply and internalcomponents.
  • 21. Box Cooling Issues Computer components aresusceptible to heat. The components operate at highspeeds and in tight spaces. The computer case plays animportant role in cooling theinternal components and isdesigned with cooling features. Computer cases have air intakevents, which are usually cut intothe sides or front of the cases.
  • 22. What isTroubleshooting? Effective troubleshootinguses techniques to diagnoseand then fix computerproblems. A series of logical stepsspeeds up thetroubleshooting process. Rarely will simply guessingpotential solutions for aproblem work. Troubleshooting is a cycle.
  • 23. Problems with theMotherboard and Processor Some symptoms of impending failure◦ The system begins to boot but then powers down◦ IntermittentWindows or hard drive errors occur First troubleshooting task to perform◦ Update drivers of components not working◦ Use support CD bundled with motherboard A few other tasks to perform if update does notwork◦ Change power saving features, such as sleep mode◦ Check jumpers, DIP switches, CMOS settings◦ Exchange the processor
  • 24. Trouble shooting the Mother board Check the SMPS power cable & DCVoltage cables Check whether Keyboard is connected properly Check the Monitor and signal cables are connected Properly Check the CMOS setting are set proper configuration Check the driver power cable and data cable Check all the Daughter Boards inserted properly Check the RESET Switch connected Properly Check KEYBOARD LOCK is Positioned Properly Check the all IC’s are inserted in the bases Properly Check the good Boot disk is available in drive A Check the Speaker connector in connected Properly
