PROCESSOR PROBLEM SOLUTION

Problem Identification   System is dead, no cursor, no beeps, no fan.             System is dead, no beeps, or locks up before POST begins.   System beeps on startup, fan is running, no cursor on Screen.   System beeps on startup, fan is running, no cursor on screen.   System powers up, fan is running, no beeps or cursor.   Locks up during or shortly after POST.             Improper CPU identification during POST.     System won’t start after new processor is installed.         Operating system will not boot.                     System appears to work, but no video is displayed

Possible Cause   Power cord failure.        Power supply failure.    Motherboard failure.   Memory failure.    All components either not installed or incorrectly installed.    All components either not installed or incorrectly installed.     Improperly seated or failing graphics adapter.     Processor not properly installed.   Poor heat dissipation.   Improper voltage settings.   Wrong motherboard bus speed. Wrong CPU clock multiplier.   Old BIOS.   Board not configured  properly.   Processor not properly installed. BIOS doesn’t support new processor. Motherboard can’t use new processor.   Poor heat dissipation.     Improper voltage settings.    Wrong motherboard bus speed.   Applications will not install or run.      Monitor turned off or failed

Resolution                                                                       Plug in or replace power cord. Power cords can fail even though they look fine. Replace the power supply. Use a known-good spare for testing. Replace motherboard. Use a known-good spare for testing. Remove all memory except 1 bank and retest. If the system still won’t boot replace bank 1.   Check all peripherals, especially memory and graphics adapter. Reseat all boards and socketed components.   Check all peripherals, especially memory and graphics adapter. Reseat all boards and socket components.     Reseat or replace graphics adapter. Use known-good spare for testing.    Reseat or remove/reinstall processor and heatsink.   Check CPU heatsink/fan; replace if necessary, Use one with higher capacity. Set motherboard for proper core processor voltage. Set motherboard for proper speed.   Jumper motherboard for proper clock multiplier. Update BIOS from manufacturer.   Check manual and jumper board accordingly to proper bus and multiplier settings.   Reset or remove/reinstall processor and heat sink. Update BIOS from system or motherboard manufacturer. Verify motherboard support.    Check CUP fan; replace if necessary; if might need a higher-capacity heat sink or heat sink/fan on the North Bridge chip. Jumper motherboard for proper core voltage.   Jumper motherboard for proper clock multiplier.   Improper drivers or incompatible hardware; update drives and check for compatibility issues.   Check monitor and power to monitor. Replace with known-good spare for testing.
