Computer not turning on
I built the following PC about a year ago:
Abit AV8 motherboard AMD Athlon 3000+ 2x512 ram 120 gb western digital ide 80gb seagate sata hd NEC dvd-r Saphire 256mb graphics card I have not had any problems with this machine until yesterday. When I try to power on the PC, it turns on for a split second then... nothing. If i press the power on again, nothing. The only way I can get anything to happen is if I turn off the power supply (or unplug it) from the switch in the back and turn it back on. Then when I turn it on from the power in front it does the same thing... turns on for a split second then turns off. Its almost like something is overloaded, like when a fuse is overloaded and keeps shutting off. I unplugged everything from it and tried a different outlet, but no help. Any ideas?? Please help I miss the internet |

Re: Computer not turning on
It sounds awfully like a PSU that has finally given up the game to be honest. What is your PSU make and model and how old is it? Can you swap it for a serviceable one to test?

Re: Computer not turning on
here is the link to the case and power supply I have:
http://www.newegg.com/Product/Produc...82E16811129155 It is pretty new and rated to handle what I have... but a bad PSU would make sense... any way I can test it? |

Re: Computer not turning on
It would be hard to test the psu under this condition you would have to put some sort of load on it, better to try another known working psu.
The fact that you have to unplug the psu to reset it has me thinking it is bad also. |

Re: Computer not turning on
Can I just add a point of warning. A PSU can easily put enough current through your heart and body (via your arms) to kill you very quickly indeed. Unless you are qualified to rip apart a PSU and then have the test gear to actually test it, you are wasting your time and risking personal injury. At best you will see burnt tracks, or a damaged component, but one damaged compononet is usually a sign or other faults.
Even then, if you can fix it, it may fail again, damaging your other components (e.g. motherboard etc). Test with another PSU, then bin it! IMHO of course.
