Re: Power problem

NO POWER Maybe you have a faulty Power Cord try replacing that first. Secondly check your powersupply's Fan if its turning. Lastly check your power button maybe its defective. SWITCH PROBLEMS A trick can be done here. Unplug it then spray the switch (Soaked) with warm distilled water with mild soap. then let it dry using a Hair Dryer. Then test! If failed, Replace the switch. If Persists then There is a problem with the Main Board or Power Driver. FOR LONG BEEPS, ONE SHORT BEEP IN AN ENDLESS LOOP, BLUE SCREEN OF DEATH AT STARTUP Try using Memtest 86+ to diagnose your memory problem. You can also try the following methods. Turn off power, Unplug. Remove the cover of your PC. Remove the memory from the Motherboard. Note on the locks! Clean the memory contacts with an eraser yes that's right a rubber Pencil eraser. It should be shiny gold. Reseat your memory to the motherboard and Test! ====================== If you are having trouble with Newly bought items save your self from headaches by returning them and demand a replacement or a refund!

No power to my desktop computer HP A1330N and no green light in the back of the power supply

You replaced power supply and your made sure you plugged everything back into the motherboard snuggly and in it's proper place? If so it might be your motherboard is bad.

Make sure you have the new power supply turned on. Sometimes there's a O/I switch on the back of the power supply. Flip it and try to boot and see what happens. You might have another bad power supply.
If so your motherboard might be burning them out.

Try removing the power cord for 30 seconds and press and hold the power button. After 30 seconds put the power cord back in and press the power button to see what happens.

Do your fans work when you press the power button? Do you hear any fans running?

What causes red led on starting?

Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.

When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?

Anything shows up on the LCD Screen?

If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.

If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.

No power only orange power light

Hi, It most likely is a faulty power supply or a motherboard issue. Remove the power cord then press and hold the power button for at least 30 seconds. Then plug it back in and hit the power button. This will release any static buildup that might be in the computer and sometimes that causes it not to boot. If nothing is happening it is more likely your power supply than the motherboard.

Try swapping out the ram 1 at a time, making sure there is one memory piece there while testing. If no! check hard drive for activity.

Computer turn on, but when it does it won't POST

It seems like a motherboard issue. It heats up, thus is not able to turn on continuously. You may need to check internal parts embeded on the motherboard llike the fan and processor before you could know what needs replacement.

When pressing the power button, the fans only come on. I checked all the connections, and tapped the power button, the fan can on briefly then it booted up. Why do this happen, and how can I prevent it...

There are a number of causes but the most likely cause is a faulty power supply. Try a different power cable to the power supply first, then try a different power supply to see if this solves the problem.

Let me know if I can be of any further assistance.
Best wishes,

Wont turn on

If you press the power button and nothing happens, most likely you will need a new power supply.  If all the fans and whatnot come on when you press the power button, but you get no video, I would remove the RAM from the motherboard, and see if you get video.  If you are still getting no video, but the fans are all coming on, there is still a slight chance that it is your power supply, but most likely your motherboard.

What does No Power/No POST Troubleshooting mean

It refers to two symptoms. No power just means the machine is dead and nothing happens when you press the power button on the computer. POST stands for Power On Self Test. This is what happens just after you press the power button - the computer checks devices connected to it then starts to load Windows or whatever operating system you have. If the computer is dead, then it is often caused by a faulty power supply (metal box where the power cord goes in. If it won't POST then an error may be displayed to tell you where it stopped during POST, or error beeps may sound to tell the technician which part of POST has failed. Sometimes, you may hear the fans and hard disk, but the monitor stays dead. This is usually caused by the RAM coming loose in it's socket or the video card coming loose/ failing.

My computer won't start! It was shut down by the start menu and when I went back to it about an hour later, I push the button in to power the computer on and nothing is happening. Yes, it is plugged in...

Unplug it and hold the power button in for up to 60 seconds to discharge.

Is there an I/O button in the back of the computer? Make sure it is set to I.
