Problem



Computer hangs after sometime.

Remedy

1.       Check whether this problem is due to any application program.

  1. Check whether the computer is stable when working with some other application.


    2.
  2. If the problem is due to an application, remove and re-install application.


    3.
  3. Keep in mind you check that all the hardware requirements are met (for using that application software).


    4.
  4. Install any service pack or software patch required for the operating system and the application. Install all necessary critical updates for the Windows Operating system.


    5.
  5. Check whether any virus has infected the computer. Use anti virus software to clean.

  7. Scan the hard disk (boot partition) to check if there are any errors in the file system.


    8.
  8. If problems are found in hard disk correct the problem and check.


    9.
  9. If the problem is still not solved, then, open the cabinet. Clean the dust inside the cabinet, by using a handy vacuum cleaner. Clean the processor fan blades.


    10.
  10. Remove the memory modules and clean and fix them in their slots.


    11.
  11. Check whether the problem is solved.


    12.
  12. If the problem still persists, then check SMPS output voltages.


    13.
  13. If you suspect that there is a fault in the SMPS, then check by changing the SMPS.


    14.
  14. Visually inspect the motherboard for any damaged components like a protruding capacitor.


    15.
  15. If you find any such electrically damaged component, send the motherboard for a service.

    4.
  4. Check if the front panel power switch is connected to the front panel header on the motherboard.


    5.
  5. Check whether the SMPS power connector to the Intel Pentium processor (Four Pin Square Power connector) is connected to the processor power connector on the motherboard.


    6.
  6. Connect the power cable and switch on.


    7.
  7. Check the SMPS output voltages.


    8.
  8. If SMPS is okay, continue the following steps from step 10.


    9.
  9. If SMPS is not okay, check by changing the SMPS.


    10.
  10. If the problem continues, it may be because of an improper processor installation.


    11.
  11. Remove the heat sink and fan.


    12.
  12. Check whether the processor is correctly installed in the socket.


    13.
  13. Observe the processor seating on the socket.


    14.
  14. Mount the heat sink over the processor and fix it on the motherboard rigidly.


  15. Connect the fan power connector to the motherboard.


    16.
  16. Now check whether the computer starts properly.

General SMPS-Swith Mode Power Supply Problem and fix

-
Problem The computer boots normally, but behaves erratically after some time. Remedy The power supply may not be able to support the load inside the computer. The internal fan in the SMPS could have failed and excessive heat inside the SMPS might have caused the erratic output voltages. Check whether the SMPS fan is functioning. If the fan is okay, then switch off the power. Remove the power cable and open the cabinet.. Check the SMPS output voltages, after connecting the power cable and switching on the computer. If the SMPS outputs are not satisfactory, then check by replacing the SMPS. Now the problem is solved. Send the faulty SMPS for a service.                 Problem After adding one hard disk drive and one DVD drive to a computer, which already has a hard disk and CD writer, the computer does not start.
