  1. Hardware Troubleshooting

  2. Definition • Hardware troubleshooting is the process of reviewing, diagnosing and identifying operational or technical problems within a hardware device or equipment. • It aims to resolve physical and/or logical problems and issues within a computing hardware. • Hardware troubleshooting is done by hardware or technical support technician.

  3. PC does not start • Power cord or cable • SMPS • Processor not installed properly Solutions • Check power cable for loose contact or breakage • Check the SMPS fuse or replace SMPS • Install the processor properly

  4. 2) System started but no display • Monitor cable loose contact or faulty • VGA card loose contact on motherboard • Monitor Solutions • Check monitor cable for loose contact and put it properly if it breaks replace with new one. • Properly insert the VGA card in PCI slot if it not solves the problem then replace the VGA card • Adjust the settings on the monitor otherwise problem with monitor

  5. Continuous beep as you start PC • RAM • System bus speed mismatch Solutions • 1. Insert RAM properly on the motherboard 2.Clear the CMOS settings by shorting the pin1 and 2 or JP1 3. RAM replaces it with working one • Configure correct bus speed in BIOS. If you don’t know values then configure it to Optimized Defaults.

  6. 4) HDD not found • IDE cable or Power connection • BIOS settings • Partition failure • Operating system boot files damaged in the HDD Solutions • Check IDE cables or power connector for proper connectivity • Use IDE Auto Detection option in BIOS for detecting the HDD • Repartition the HDD using bootable disk or any third party tools • Restore the bootable files by starting the computer with boot disk and type the following command prompt a:\>sys c:\

  7. FDD not found • FDD cable or power connector Solutions • Connect data cable & power cable to FDD. Replace the FDD 6) Keyboard not found • Keyboard connection • Keyboard port failure Solutions • Check the keyboard cable for proper connection or damage • Give it for repair at authorized service center

  8. 7) Mouse not detecting • Mouse cable faulty • Mouse driver corrupted or not loaded • Mouse is dead Solutions • Check it for proper connection and replace it with working one • Load the mouse drivers from the vendors diskettes replace it with working one. • Replace it with working one.

  9. 8) When we connect both HDD & CD-ROM, HDD is not detecting • Jumper settings on a device • BIOS settings Solutions • Check for master & slave setting on backside of the devices. The device, which contains operating system, must set to master and other to slave. • Properly detect the devices using the IDE Auto Detection option in BIOS.

  10. 9) System booting slowly • Insufficient disk space on default drives • Virus problem Solutions • Free the disk space by removing all unnecessary files and run the disk defragmentation utility. • Remove virus by running anti virus application

  11. 10) Unable to remove BIOS password • Jumper settings Solutions • Remove all power connector from motherboard and start pin 2 & 3 of JP1 and set back to pin 1& 2 11) CD auto play not working • Device manager Solutions • Go to control panel then system device manager select CD Drive right click properties and then enable auto insertion

  12. 12) No clarity • Display resolution Solutions • Load display drivers properly & set correct resolution (no: of bits/clarity ) 13) PC Speaker, HDD led, power led & other LEDs not working • Front panel port Solutions • Check indicator connectors for proper connectivity on motherboard front panel port

  13. 14) Check sum error • CMOS battery Solutions • CMOS battery weak. Replace it with working.
