Question about PC Desktops

1 Answer

PC seems powerless except.....

One of our PC's will not turn on. So far I have opened the box up and have noticed there is a green LED light lit up on a circuit board but that is about all that occurs. When I unplug and plug back in the power cord one of the fans rotates several times and then stops. Any suggestions on where to start troubleshooting next would be appreciated.

This sounds like a short of some kind or bad power supply or motherboard.

  1. Take any components that are not necessary to boot the computer. Try turning it on again
  2. Try taking all parts (motherboard, power supply) out of the case and then put them back in (I know that sounds weird, but it has worked twice for me before).
  3. If you get to this step, either the motherboard of power supply is shot. The easiest to try would be a power supply. Replace it if you have one laying around or borrow one out of another machine for troubleshooting purposes. This is assuming they are standard ATX power supplies.

How do you open the case on an ER1401-57 to upgrade the RAM?


Hello there, I am the expert that will be helping you today. My name in damnor01.

Welcome to Fixya.

I do recommend that a computer technician do this for you as opening the chassis will void warranty support.
Contact the place of purchase in this regard.

Pc turns on, but that is as far as it gets, nothing eles happens, help


You need to be a little bit more specific. Please indicate what happens after you turn on the PC. Is the LED on the CPU green? Is the monitor light green when you turn on the PC? Are there any error messages on your screen? Also, are there any beeping sounds coming from the PC?

Amber light flashing on switching on the pc why?


HI,

A blinking amber light means that there is a problem with the power supply or the motherboard. I know that could be a number of things. Perhaps you could give some additional information.

1) Does the green light come on on the motherboard?
2) Do any/all of the fans work? Power supply or computer cooling.
3) Do you get any other lights? CD/DVD player?

You may have to get someone to see if your power supply outputs are all good.

I hope that gives you some starting points.

Thanks for using Fixya.

Gateway 503gr has no power, the standby light flashes green when I remove power. Tried new PS and the standby LED stays lit. I then tried both new and old PS disconnected from board and shorted...


Disconnect everything from the motherboard except the power supply connections and cpu fan. Install one stick of RAM and connect your monitor. Then try starting up. See if you get any BIOS boot messages. This will tell you that the board and processor are okay.

With what you say you've tried already, I'm thinking you might have a bad processor. Most every other problem would result in some kind of error like POST beep codes or messages on screen. If the system still doesn't boot with the bare minimum parts installed, replace the processor.

Green LED on Dell Inspiron Desktop 530 - all OK?


Yes, on most desk top the green light in the back tells you that you have power to the cpu. Even though the unit is off it is telling you that the current supply is still there. This is a good feature if you move your unit as soon as you plug it in you know if the outlet is on or not.

My Everex Impact GA3400 acts as though it is not getting any power to it. It was working fine and just shut down and now I can't get it to start


it could be a busted power supply. check if the green LED lights in the motherboard when the unit is plugged (even if it is not turned ON, it will light). If the led is not lit, the power supply is defective.

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

Pc will not power on .Press main power button on the front of the server,all fans work and front Disk LED glows yellow. Power LED at rear glows green but LED on the front(light bulb symbol) not lit....


Open the case and check the connection between the case power button and the motherboard. unplug that connection and short out the pins on the mb. The computer should start up. If it doesn't, there is something wrong with the mobo. If it does, there is something wrong with the switch, or the connector wasn't tight.
