Mine has done the same thing many times. Every time I lose power to the house my computer won't turn on and the power light blink. While the computer is plugged in, unplug the main power supply to the motherboard and re-plug it in. The light next to the plug on the motherboard will come on steady now and it will work. It's worked for me many times. I don't know the problem and I know how to get it running again.

How do I know if the power supply is bad on gateway gt5676 computer? I push power button and nothing happens. I unplug it and the green light flashes on the power supply( Bestec ATX 300 12 EB3). Plug it...


u can buy power supply testers, just a device you plug the power supply into, or try a new power supply. but if nothing is happening no fans etc theres a good chance its just the power supply.

Dell Inspiron 1721 will not power on,light on power supply flashes rapidly.


First, try and take out the battery and start the computer with just the power adapter. If the power adapter is still blinking, replace the power adapter. If the computer turns on with just the power adapter, replace the battery.

If the battery status light rapidly flashes amber, the battery may be defective. Purchase a replacement battery from Dell.

If the power supply status light flashes, the power supply may be defective. Purchase a replacement power supply.

Computer will not turn on....how do I check to see if power supply is faulty? I have power supply removed and have a tester to check for dc voltage etc


I just went through a heap of troubleshooting with power supply issues before swapping psu's and finding this was the solution to my problem. Had a closer look at my psu that was faulty, the green light was flashing on the psu, unplugged all components and thought that I now had a non-flashing green light on my psu, on closer inspection the light was actually flashing very fast so appeared to be an almost solid light...the psu was stuffed so replaced it and no more issues. If your power supply has a green light check to see if it is flashing when plugged into voltage with nothing connected to it. If it is a solid light then it is probably ok.

I have a flashing light on the fan end of the Dell power supply and the tower won't power up.


A flashing light is suppose to mean that the power supply is receiving voltage from power cord but is not functioning correctly. Here is a page with the information.

FLASHING RED LIGHT ON 360


Make sure that the power supply is cool loadTOCNode(2, 'whattotry'); The red light may indicate that the power supply is too hot or it has already overheated. If that is the case, you should let the power supply cool for several hours in a well-ventilated space. Turn off the Xbox 360 console and don't turn it back on while the power supply is cooling. This will allow the power supply sufficient time to cool. As soon as the power supply has cooled off, the power supply light will change from red to orange, and you can turn the console back on.

If the power supply light is still red after you have let the power supply unit cool in a well-ventilated space, the power supply unit may require replacement. You can contact Xbox Customer Support at http://www.xbox.com/support/contact (http://www.xbox.com/support/contact) for information about how to replace the power supply.

Make sure that the power supply is plugged in correctlyFor further details go to this link

Three red lights


Three lights flash red on the Ring of Light (RoL) on the front of your Xbox 360 console. The upper-right quadrant light is the only light that does not flash red. CAUSE: The three flashing red lights may indicate that there is a hardware problem with your Xbox 360 console. MORE INFORMATION: If you are experiencing this problem, you can submit a console-repair request online. However, before you submit your request, first try the following two steps to verify the problem: 1. When you turn on the console, look at the light on the power supply. The power supply light should illuminate green even if the three lights on the Ring of Light flash red. If the power supply light is not green, please follow the steps in one of the following Microsoft Knowledge Base articles: 906101 (http://support.microsoft.com/kb/906101/) Troubleshooting your Xbox 360 Power Supply when the light is red 906102 (http://support.microsoft.com/kb/906102/) Troubleshooting your Xbox 360 Power Supply when the light is orange 906103 (http://support.microsoft.com/kb/906103/) Troubleshooting your Xbox 360 Power Supply when the light is not illuminated 2. Turn off the console. Wait 10 seconds, and then turn on the console again to see whether the problem re-occurs.If your console continues to display three flashing red lights, your console may have to be repaired. If none of these help, pease contact Xbox support at http://xbox.agent.asahost.com/ to talk to a live agent.
