(bad) trip report
Gents:
Trying my first buildout from mobo/CPU combo and separate case. 'Pre-tested' Ga-7VT600/Barton2600+ , and ANTEC400. Legacy CT-mx400 Vidcard and Samsung 256 DDR333 RAMstick. For initial test no drives etc were connected. Ground_strap used consistently while assembling components. After assembling combo & case, and connecting surge_suppressor, monitor, mouse, kboard & sound I turned it on. Got a quiet POP! No smoke or smell. All fans started turning then quickly stopped. No display or boot. Retrys give no display or fans. I am not feeling good about this. Comments appreciated. My first idea is to remove RAM & Vidcard to see if CPU/case fans work. Then recheck F-panel pins ... I did take some care initially to get them right. If no positive result from these checks, maybe I damaged the mobo during install, though the (6) brass (case) spacers lined up perfectly with mobo screw-holes |

Have bad experience with ANTEC TruePOWER. One failure was attended by a
quiet snap. JPS "ray hartman" wrote in message newsan.2004.01.08.21.05.49.413057@SPAMBEGONEqwes t.net... Gents: Trying my first buildout from mobo/CPU combo and separate case.

If you need to check a power supply there are several websites showing
voltages off of each pin of the various plugs of the power supply. You'll need a voltmeter. An ATX power supply has to have a load on it before it will start. Directions on testing the voltages generally tells one to use a resistor of a certain ohm and wattage rating. Instead, I just hook up an old hard drive and grounded the pin necessary to start the power supply. Worked great. Was able to test voltages without a problem. jpsga wrote: Have bad experience with ANTEC TruePOWER. One failure was attended by a quiet snap. JPS |

The ANTEC can't push 400W into the mobo no matter WHAT the shorting-test shows. I don't happen to have a voltmeter: maybe it's time to see if NewEGG.coms RMA policy is as good as its reputation. |

Bought a new GA-7N400 Pro 2, put in my existing XP2400+, etc. Got Win2K Pro loaded up on the RAID array, then shut down to connect my data drive to the IDE controller. Put the power cord back in my power supply, tried to turn it back on, nothing. No POST beeps, nothing. Only thing that happened when pushing the power button was the fans in the system would briefly spin up, then quit. Pulled everything out, tried it in my wifes PC, CPU, RAM, video, all good. Figured the board died. Took the board back to the store I got it from (only paid about $10 more than Newegg), they only exchange. They took the board in back to test. Came back a few minutes later, the board was working!?!? Even took me back to show me. Took it home, set it on the static bag, put in the CPU, video, ram, and connected up the power supply. Same problem. Hooked it up to the PS in my wifes box, powered right up. Power supply that failed? An Antec TruePower 550. Luckily I tracked down the reciept, and Antec offers a 3 year warranty, so I shipped it back to them. Right now I'm using the 350w PS from my wifes PC. Seriously peeved me off too.

I did have one other problem in regards to this symptom. On a cheap case the
cheap ON/OFF switch would get stuck closed. The power would come up then turn off. JPS "ray hartman" wrote in message newsan.2004.01.09.04.36.36.506660@SPAMBEGONEqwes t.net...

My power supply had one of the voltages higher than it was suppose to
be. While the machine would boot, it had problems with constant crashing. Check the voltages and make sure each is within the +/- parameters for each voltage.

BigT: Don't have a voltmeter, but wish I did. I'm more hep now, to the equipment needed to build-out from parts. I had figured that several successful build-outs from supplied "barebones" units [ and THAT was getting to be a bore ] was a fair preparation, but that assumption is just not so. Even a prudent choice of supplier and quality parts is NO assurance stuff will just work when plugged together. I'm wondering now whether the initial failure rate for a parts-built computer is more like 50% than 5% ? |
