Get into your bios (usually by hitting del key as sys. is booting up). See if your hdd is detected in the settings. You can also put a screw driver on the hd (while pc running) with the handle end to your ear. You will be able to hear the drive spinning if it's working. If you don't hear it, detect it in bios or feel it spinning then try another "good" hard drive. A bad drive that's not working should give an error message like "no drive detected" or like that. Because you have a black screen (if no error messages) then I would check your power supply since you say your ethernet light is flickering. How about the sys. fan & cpu fan, are they working? Are other rom drives lighting up? It could be a few different things hopefully one of these will solve your problem.

The hard drive could have failed..Try a hard start to see if it will react. Do you get any beeps?? a warning beep or beeps may indicate a hard drive failure. Try to get into C-Mode set up. click alt/cntrl/del as you turn on the set.or alt/cntrl F10. Hard drive failures can happen if ther is to much written to the drive or just a plain 'Crash'.

HP Touchsmart IQ526- Black Screen and Amber LED please help! No display. Is this a hard drive issue?


Also had this issue on the Touchsmart IQ526. Removed the CMOS battery, waited some minutes, then powered on. The power button remained blue and had video again. Reinserted the CMOS battery and put the unit back together. Note - the battery was on the mainboard.

I turn on the Gateway and the words Gateway come on screen, then it goes black. The keyboard is on then off then comes on again, Screen remains black.


You have a problem with the operating system. It has crashed. You will need to reinstall the operating system in your computer. Before you do that you need to back up your file in your hard drive.To do that you need a 2nd computer get a hard-drive closure external take out the hard drive of your gateway. and plug it in to the external closure and plug it in the computer and explorer and move the files you need to the other computer. After that put the hard drive back into the gate

Your computer came with a recovery disc. Use that to reinstall your computer and software. That will help your problem. Update your computer to make sure it doesn't fail again.

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.
