Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes PC
More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.
Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

Power light blinking on nv53a gateway


Your Gateway laptop comes with a series of LED lights that alert you to the state of your computer. You'll notice there are blue, purple and red lights that either blink or display solidly. Each light, blinking or solid, has a different meaning. The blue blinking light on your laptop indicates that it is in Standby mode. Your laptop goes into Standby when you close its lid without shutting down the computer. To turn this light off, you'll need to take the computer out of Standby mode, and if you want to ensure that the blinking blue light does not return, shut down the computer after each use.

Open the lid of your Gateway laptop and press the power button. Once Windows loads, enter your password if required. The blue light will no longer be blinking because the computer is no longer in Standby mode. Shut the laptop off when you finish using it rather than simply closing the lid to stop the blue light from blinking again. Click "Start" from your Windows desktop and click "Shut down." Change your computer's power settings to keep if from going into Standby mode when you close the lid if you'd rather not shut down your computer every time you use it. Click "Start" and click "Control Panel." Click "System and Security" and then click "Power Options." Click "Choose what closing the lid does" from the list of options on the left side of the window. Select "Hibernate" from the drop-down lists under "On Battery" and "Plugged In." Click "Save Changes." Your laptop will now bypass Standby mode when you close the lid and it will enter Hibernate mode instead. Hope it helps.

Is there a way to stop the power button light from flashing when the computer is asleep?


No. I don't believe so. I think the purpose of the blinking light is to let you know your PC is not shut down, and is in sleep mode.
If it is a desktop PC without battery backup and the power goes out, you might lose data on anything open and not saved. Or worse it could corrupt the OS (operating system).
If it is a laptop and not plugged in it will eventually run out of juice.
I see many of people using sleep mode exclusively, mostly on laptops.
It is a good practice to completely turn off the PC if it won't be used for an extended time, or at least restarting (warm boot) or shut down (cold boot) once a week so windows can install updates that it has downloaded.
Doing this also refreshes the loaded Operating system.
Your options to stop the blinking light from annoying you would be :
1. completely turn off the PC (recommeded)
2. a small piece of electrical tape
3. A dab of black paint

Keeps blinking. I've shut it off, and cancelled all print jobs - even unplugged it. Keeps blinking. Says there is an operator error


Try this:

1. Turn off printer (use button, don't unplug)
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not, press the Power button once more.

If this not help may the print head is defective.

Dell XPS 200 Computer shuts off leaving blinking amber light


3 most common solutions to your problem are:
  1. Bad power supply; once it heats up will quit without warning
  2. Bad heatsink/fan; processor heats up and will lock up your Pc
  3. Bad motherboard
Try opening the machine and give the inside a thorough cleaning, paying special attention to the heatsink and fan. Once clean and you've ensured the fan is operating, put it back together and see if your problem is fixed. If not, a new power supply will likely fix your problem. Best of luck.

No picture or audio.power light blink on once and turns off


The real deal here is the protection circuit has activated. This is caused whenever an excessive amount of current is being drawn from the main power supply. Upon detection of same, it immediately takes over the power management of the set and shuts it down. The clicking sound you hear is the ON relay turning on the set, but immediately the power mangement system shuts it OFF. You should hear two clicks, but they may be so close together that it sounds like one click.

This set is getting rather ancient and I would not recommend you spend much money on it for this reason: It is highly likely that once the set if repaired that another failure would occur. This is because of the law of averages; the first failure is often followed by another failure from anywhere within the set.
