Power goes off by itself, then boots up again

Have already installed a new power supply, and new power cord, checked the power strip (surge suppressor) and wall outlet, but this problem keeps happening. What else could it be? This is an Insignia D400a (Best Buy in house brand)

In computers, any number of problems can cause this - bad RAM, bad hard drive, fried voltage regulator(chip in a laptop), overheating cpu, overheating video card/gpu, there are even a few device drivers that can do this if they become corrupt. Usually, however, its not an issue with the power supply/power source.

I would try swapping the RAM with new(or known good) sticks. Also, make sure the system is clean, and no dust has built up in it, especially in/around the fans.

If the RAM swap is unsuccessful, and the system is clean, check and make sure the fans spin when the system is on.

Power down the system, disconnect the data and power cable from the Hard Drive, and turn the computer back on - you won't get into the OS, but you'll be able to determine if the issue occurs w/o the hard drive connected.

Ultimately, it may come down to a bad motherboard.

depend on where the surge is. from power line, then most likely your psu is fried. if it comes from the modem/telephone line then probably your motherboard is fried.

Not booting up


>Start with the power. Is the power cable plugged in correctly into a UPS, surge protector, power strip, or wall outlet? Is the wall outlet where the power comes from controlled by a wall switch that was turned off accidentally? Is the power strip turned on? Is the light on the UPS or power strip on, indicating that it has power? Is the power cable plugged into the back of the computer correctly? The socket on the back of the computer where the power cable goes in is part of the power supply in your PC. Some power supplies have a separate on/off switch, usually labeled 0/1. Is that switch turned on? Check the voltage - most power supplies have a switch to change between 115 and 230V - and make sure it is set correctly.

> Is the power cable for the monitor plugged in correctly? Is the monitor turned on? Is the cable from the video card to the monitor plugged in correctly? Is the video card seated properly? Take the cover off of the case, remove the video card and insert it again properly, then try again.
If everything is connected and powered up correctly, push the power button again and pay close attention: do any lights on the front of the PC blink or light up? Does the fan in the power supply start whirring? This could indicate a hardware problem. Try to think what happened right before the problem started. Did you add a new piece of hardware? If so, it might be faulty or not installed right. Remove it, then try again. If everything is fine without the hardware, try to reinstall and configure the hardware again. If that does not help, try exchanging it and see if that corrects the problem. If the error persists, narrow it down systematically. Remove everything but the CPU, memory, keyboard, and video card, then boot again. Does the error still occur? If not, then add one piece of hardware and try again. Repeat until one new component causes the error and you now know who the culprit is. If yes, then reseat your CPU, memory and video card and try again. If the error still happens, try replacing the CPU, video card and memory one by one to see if one of them is the troublemaker. If that does not help, you could have a bad motherboard. Check the motherboard carefully for any signs of damage. Also check for shorts, a metallic object could have found its way onto the motherboard, or the motherboard is not installed correctly and touches the case somewhere.

Audio would crackel then screen would scramble, now unit just beeps when poweredup.


Sounds like you are the victim of a power surge. If you do not have a surge protected outlet strip, get one before you fix the pc (or buy a new one). If you do have a protected strip, you should know that they are only good for one hit. If ever, in the past life of a protected strip, it is tripped off, that is, you had to reset it, the strip is no longer protected. It will work for an extension cord (if it wasn't hit to bad) but it no longer protects your stuff (and any warranty for your stuff is now void).

As far as the pc goes, its probably toast. You could crack it open and look at the motherboard, inspecting it for burn marks but the damage may be hidden inside the power supply or somewhere like that. If your set on saving your pc, you may be able to pull the hard-drive, mount it to a different pc set up, and boot from it, providing the hard drive is not damaged (ask a tech friend to help you if you go this route). You may then be able to pull any files off of it you want to keep. Then throw away the old drive, it can't be trusted.

Power cord repair


You should be able to get out under $50. Just replace your supply. It should come with a new cord. Make sure your new power supply: (1) has greater or at least the same output watts of the one that you are replacing (should be on a sticker on the outside of the power supply itself) (2) has the correct connectors. Older power supplies did not have the power connectors for pentium4 and later processors or SATA hard drives. Trying to repair your old one may lead to a fire, or worse yet, arcing and voltage spikes and surges which will damage your computer.

Computer wont boot hear one beep from motherboard over and over


If your power supply is bad, there is typically a much cheaper way to fix it rather than purchasing a new one.

If you know a little about electronics or know someone who does have them open up the power supply and check the capacitors. Often times when a power supply goes bad its the result of capacitors going bad.

If you notice on the ends of any capacitors a brownish/whitish discharge or "bulging" then the capacitor has gone bad.

A new one typically cost less than a dollar and replacing it is fairly easy if you know how to solder.

Let me know if you have anymore questions and hopefully if this is the case you can save some money.

Emachine with XP home edition doesn't start


Hi hearalso, down to the basic's. Replace power cord.
No help there than, remove the case's side panel to expose the motherboard. (Normally it is the left side panel while facing the front of the PC.)
Look closely for a small (green in color) led light. The power cord must be connected to the PC & connected to you're power strip but do not press the power on button on the PC.
The green led tell's you the board is receiving 5volts. Check all connections. Un-plug & reconnect every data & power connector in your PC. (Double check). There is a fuse inside your power supply that may have blown. Check you're manual page, Approva Statements B-1. Fuse Warning Instruction Caution.
Check fuse in power supply. (Unplug power cord before opening).
If you can not power up the PC after all of the above than if possible, swap out the power supply.
Replacing the power supply is the last step.

If you have more questions, feel free to ask.
Good Luck!

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
