Uh Oh

[TwoBills]

Check me out here before I ship this mobo back to Tiger.

Chaintech 7vif4 mobo w/2500+ Barton, (2) 256mb ram, Fortron 200w psu, (1) hdd, (1) cd/rw. New build, system was up and running fine for 4 or 5 days (using a Knoppex live cd for os). Then bam! Nothing. Uh oh. Total crash. Not even a psu fan.

Pulled the power connector, jumpered the pins and the psu fan comes on. Metered all the power sources and they read ok. But I get nothing, no cpu or case fans, nothing, when I plug it back into the mobo. Any thing else I can check before I send this thing back?


Poly fuse opened up. After it cooled down the cpu and case fans came back, but that's all. Still won't boot, cd won't eject, power switch lites up, but doesn't work (shuts down with psu switch only).

Here's my thinking: Spiked the board (maybe with a new el cheapo keyboard), popped a poly fuse (but not soon enough), and crapped the mobo.

My next (best) move: RMA the Chaintech to Tiger, buy a higher quality board from NE (will start a new thread, in mobos, on that), and use the new/repaired Chaintech for a bu/troubleshooting tool. Take the suspect keyboard back and get my $9.

Am I thinking right or still poed re: the 3am crash and missing something?

Trying another PSU would be where I would start, along with booting barebones out of the case. If it still doesn't play nice RMA.

This is my 1st build, so I was extra careful: Booted it barebones before it went together, added peripherals one at a time, etc. The system was running fine for 4 or 5 days when the poly fuse popped.

As far as the psu, I've got readings of 12.10, 5.10, and 3.10vdc. Seems like this should be OK. I don't have another psu, running a Fortron 200w now. May be worth the $ to step up to one of the new Fortron 270w, just for piece of mind. Hm, I do have a 300w el cheapo, in this machine, that I could test it with. Nah, better to just give up the $30 for a 270w and be done with it. Worst case scenerio I end up with a 270w in my case, with a new, quality, mobo, and a Fortron 200w and an elcheapo Chaintech for troubleshooting, testing, or kid's machine.


OK, here's the new plan: Buy a 270w Fortron, was looking for an excuse anyway, and see if that's the problem. Kinda doubt it, but what the hey. Pull the mobo and try to get it to boot, 1st w/the 200w and again w/the new 270w, when it comes. Gonna do that now, before I order the new psu. Go from there. Oh, yeah. Return the suspect, el cheapo, keyboard.

Thanks for the feedback, Dapun. Anybody else got any suggestions?

Does the mobo have an AMD CPU protection feature? If so, maybe you need to clear the CMOS. (IMO, folks that buy from Tiger Direct should be left to stew in their own juices... )
.bh.

There's the :sun: !

Hah, knew I was gonna hear it about Tiger. Finally solved the problem, but took the thing apart before I found it, including the psu.

Got some positive stuff out of the whole thing:

---Hey, I got to build my machine again. I posted in another thread that I was "savoring" the build. Well, enough of that. Time to go forward.

---Dressed my power harness while I was at it. Improved the air flow a bit.

-Now the goodie. I had an intellisense T-1000 (digital temperature sensor) just laying around, so while I had the mobo on the table, figured I'd adapt this thing. Glued the remoted sensor to the outside of the cpu heat sink, out of the air flow, and tapped some power from the unused 12vdc cable.
35ma. draw. Works like a charm. 41 degrees C on the outside of my heatsink. Digital readout looks good, too.

OK, OK. Stuck with me this far, I guess it's time for the noob to fess up. My imput power selector switch was centered. Set it to 115vac and every thing was cool. Didn't notice it until I had the box gutted and the psu was in my hand. Whatda ya gonna do? Just another adventure in noob land. Oh, yeah, I switched the elcheapo, suspect, keyboard w/my old box, just to see. Something caused the poly to pop.
