Just built a new system
Just built a new system, with new motherboard, new hard drive,
new CPU, etc. and keep having this wierd glitch. Only happens once every morning! I turn on the computer, the moterboard gets powered, but there's no video signal, and the drives are silent. I disconnect one of the drives (both power & IDE, just power is not enough!) and then the system boots up normally, from the second drive. I power it down, reconnect the first drive, and it still boots OK, until the next morning. wtf? Motherboard: FIC KT-748 CPU: Athlon XP 2400+ HD: two WDs 80gb Memory: 1gb |

What make/model/capacity power supply? Dave |

Try a good name-brand like Sparkle/Fortron, Antec, Delta, etc. Can't guarantee it's the power supply but unless you have another available to swap in for testing, that's the first part I'd replace. Does your motherboard BIOS or WIndows utility show good voltage levels? If you can check the voltage on the power supply leads with a voltage meter that'd be good to do too, especially when it's in the on-but-no-POST state. Dave |

After ~hour: VCORE 1.61v VCCVID 1.84v 3.3v 3.28v +5v 4.94v +12v 11.71v -12v -11.78v voltage battery 3.26v CPU 49C system 36C CPU fan 2960rpm Is this ok? == GZ |

That would be when read with a voltage meter, the 12V reading is often low in the motherboards' BIOS or windows utility when the level coming from the power supply is correct. If the system were in front of me I'd swap in a different power supply, and even if it didn't work still I'd leave the other power supply in it because the original isn't very good. Dave |
