PSU died. Has it killed my motherboard too?
Hi, newbie here...I dont know a lot about P.Cs and really need help.
My 8 week old P.C, custom built from a (supposedly) reputable Ebay store has died on me and I am distraught. The PSU has died on the machine. I know this because I have made 'progress' by fitting a new PSU. When the original PSU failed the machine would not power up at all, but would momentarily stutter in to life as I pressed the case power switch but would then die as I let go of the switch. By fitting a new PSU I can get the machine to power on. The processor fan starts to run but nothing else happens. There is no 'beep' sound that is normally heard as the machine boots up. The large LED light on the front of the case that used to illuminate green when the machine was switched on now illuminates red. My friend says that the PSU has probably blown my motherboard and told me to check the capacitors to see if they look swollen. I have done this but they look ok. My machine spec is as follows:- Pentium 4 3GHz, 2GB RAM, ASRock 775 VM800 motherboard, 80Gb HD, 450W 'Win Power'??? PSU, X-Blade case. To be honest I have had my doubts about the machine since I got it because when I think about it now there has always been a strange smell eminating from it. Also whenever I was using the machine and running programs the tone of the fan running inside the machine used to dip up and down. Is this normal? The machine is under warranty but I am livid about the prospect of sending it back after only 8 weeks, espacially when I have to cover the courier costs. If I send it back I am concerned they will simply replace the damaged PSU with one of exactly the same type, because my hunch is that the PSU is a poor quality one. So what do you think? Has the PSU ruined my machine or is there something that I have missed? Your help would be very much appreciated!!!! |

I was very stupid in that I spent loads on the system, and used one of these very cheap power supplies, it died, and so did the mother board. All I had to do to check this was pop in a working power supply, not sure if it is the correct way to do things but it did ok for me. Hope this helps Vaughn |

I read a review once about a 520 watt power supply. It was in fact 520 watts, but it was 520 Watts INPUT! I thought my power supply died recently (it was almost dead anyway). The actual problem was a stop error causing windows to reboot (found later when I disabled auto reboot) due to a bad sound driver. I'm still glad I replaced it as the +5V rail was droping below 4.6 V. That reminds me, I need to connect the power to the firewire card (finally found out what that connector was for) and change a few jumpers to prevent an overload on 5VSB. |

PSU died. Has it killed my motherboard too?
Thanks for the replies, the broken-down PSU spec (of which I have no
real understanding!) is as follows :- "Win Power" switching power supply, model ATX-450. Max output power = 450W. Input : 115VAC 10A max, 60Hz 230VAC, 5A max 50Hz. Output : +12V 20A max, +5V 40A max, +3.3V 28A max, -5V 0.5A max, -12V 0.8A max, +5V/SB 2.0A max. So was this good enough to run my machine?...because no doubt the dealer will just replace it with like for like. If anyone recommends a particular PSU what is it, and how much will it cost in the UK? From what I described then does this sound like my motherboard has gone too?...or can someone suggest why the machine wont boot? |

Before tossing the motherboard use standard motherboard troubleshooting procedures. (erase CMOS if that does not work remove battery and unplug power for 15 min, if that does not work do over but boot without battery to see if it will boot that way). I deal with substandard equipment all the time so send me an email (the address is valid). |

Cant see any link to email you! |
