My samsung R540 pc will start for a few seconds and shut down again


It sounds like your power supply has died. I would suggest a replacement.
You also may need to reseed your ram as that may sometimes be the issue.

I'm sure this is a problem for most. HP Pavilion dv9205us starts up, fan engages, Led's light up, drive attempts small start, but stops and after 15 to 20 seconds shuts down with a 1 second flash...


Hello.

Could be a power issue.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Does not boot up, fans start, internet plugs light, clicks on and off.....seems this is a common problem for these machines, what is the fix?


Instructions
  1. When you press the Power button to start the boot process, the LED lights glow while the computer verifies that there is sufficient electrical power to activate the hardware.

    Effect & Solution: When you press the power button, the LED lights on the computer do not glow or the LEDs blink briefly and then stop. There is no sound of the fan or hard drive spinning, and the screen remains blank. The computer will not start if there is insufficient battery or AC adapter power.
  2. The BIOS queries various hardware components used for the startup boot process.

    Effect & Solution: When you press the power button, the LEDs glow but there is no fan or hard drive sound. The LEDs may glow briefly and then go out.

    Or

    The LED lights blink, stop, and then blink a second or third time, but there is no sound from the computer and the screen remains blank. The sequence of the blinking lights indicates a specific error code.

    Or

    A series of beeping tones is heard. The sequence of beeping tones indicate a specific error code.

    If a hardware component has recently been replaced, or if the PC has been jarred or shaken, there may be a loose connection to the memory chips or hard drive which prevents the computer from starting.
  3. The BIOS loads the basic input (keyboard) and output (advanced LEDs / display screen / boot drives) devices into memory.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, but then the boot process stops and a black screen - with an error message - displays.

    The boot check has detected a communication error or conflict with a hardware component that must be corrected.
  4. The BIOS loads the Windows operating system and starts the services that allow low-level control of all of the background operations.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, the HP or Compaq Logo displays on a black screen, but then the boot process stops and a blue screen - with an error message - displays.

    The boot check has detected a hardware driver error or a software conflict that must be corrected.
  5. Control is transferred to the Windows loader to initiate the display of the advanced settings in the Windows environment.

    The Windows logo displays during this step.

    Effect & Solution: When you press the power button, the computer performs all the steps in the boot process, but after the Windows Logo displays, the moving Windows progress bar or the rotating cursor stops moving and the boot process stops.

    An error message may display on a screen with the Windows logo. In some instances, there is no specific error message.

    Or

    A black screen appears and the computer attempts to restart.

    The Windows self-check has detected a software conflict that must be corrected.

When pluged into outlet fans spins and doesnt stop, wont boot


Fan spinning hard is usually a CPU issue.
If you've made any hardware changes to your computer, undo them. This happened to me when I was trying to upgrade my Processor (CPU) and I had the wrong kind.
