Computer Died - Won't Boot

Helloooooooooooooooooooo Short Media. How have you all been?

My computer died. Overheated or something, I'm not sure. I put it together a few years ago - it's an AMD 2100 system with a Soyo Dragon motherboard, a couple of optical drives, and a couple of hard drives. It has a generic case & PSU, and I always felt that was my achilles heel.

Yesterday, my girlfriend was playing The Sims and it rebooted. This had happened before, and we followed the instructions on Maxis' website, shutting down unneccessary processes and it fixed the problem.

But yesterday, no matter what she did, it would shut down after a while. Since it rebooted itself, she just kept on going from where she left off (she was installing things in the Body Shop and almost done).

Then it just shut down and died completely. Pushing the ON button does nothing, there's no reaction.

At first I thought it was the PSU. Like I said, I always felt that was a weak point, and it felt hot to the touch. But later, I saw that it was supplying power to the motherboard - the ethernet light is on, as well as a few other lights.

Then I opened the case and thought it might be the CPU - the CPU is strangely close to the PSU (bad case), and who knows if maybe a fan somewhere died.

But then I realized that when I was building the computer, the motherboard would boot even if there were problems with the CPU, and it would spit an error message at me.

So here I am. Something seems burned out. Or maybe the power button just got disconnected somehow. I really don't know.

I'd like to, first of all, fix what's wrong so I can get my computer back. I'd like to do this with a minimum of cost/annoyance. If I can isolate the problem now, it will eliminate unecessary trips to the store, or days of waiting for parts.

Secondly, I'd like to fix the "real problem" so it never does this again. While this is of secondary importance, I realize that it may make more sense to buy a few more components up front to safeguard myself in the future.

Third, and somewhat off topic - why don't they make external power supplies? It seems that this would fix a lot of problems for a lot of computers.

Thanks!

    Is there a power connector loose?

    I just double checked every connection I cound find, and everything looks solid.

    I also removed the front of the case and double checked the wires going to the power lights and switches.

    What Soyo Dragon? Early-revision nForce2 chipset?

    Have you checked the board for bulging and/or leaking capacitors? That motherboard is certainly from that era.

    Oh yeah, I've RMAed two soyo dragon boards with burst and leaking caps.

    Soyo is really crappy about their RMAs - they charge a $5.00 "handling fee" :shakehead

    total crap... All the other manufacturers replace it for the cost of shipping.

    When I got it, I'd seen a lot of great reviews for them.

    Any way I can test the MoBo to see if it is the problem?

    Checking for bad caps is a visual inspection. In the attached pic is a sample of bad caps. The two caps top left are the bad caps as one has started leaking and one is starting to bulge. The rest of the caps are fine.

    If your PSU is hot to the touch, there is a possibility that your PSU fan has dead. So, when your PSU overheats, it shutdown down your system without warning.

    Thanks for the pic. I checked my caps & they all look fine - silver, flat, still sealed.

    Ah... there's a switch on the back of the PSU. When I turn it off, the lights on the MoBo go out.

    When I turn it on it makes a buzzing noise.

    I stuck a pen in the fan & tried moving it. It was hard to move, and it creaked - the buzzing noise.

    The fan in the PSU did die, a horrible miserable death. WTF could do that?

    So, I know I need a new PSU. Any recommendations? Case/PSU recommendations also accepted.

    Sounds like the fan's bearing ran out of lubrication and seized up.

    As for a recommended case+PSU, I like the Antec SLK3700 case. Others may have better recommendations for a PSU or a case+PSU.

    Fans die. It runs in the hottest environment in your computer, and rarely has dust removed from it -- if any fan is going to bite it, it's going to be the PSU fan.

    In order of price, I suggest:

    Antec True series.
    Antec NeoPower series.

    Pick the one that your wallet likes.

    My wallet likes cheap.

    In 3 years you guys aren't going to be saying "What did you buy an Antec for?" Just kidding.

    Thanks for the advice, I'll keep you updated.

    is there a way to actually save a clogged-bearing fan? ive tried soaking them in alcohol but it didnt do anythging. Is there a method besides replacing for all you smart asses, of cleaning the bearings of a fan?

    Fan maintenance

    Edit: I use sewing machine oil to oil my fan bearings.

    Armo, that has to be the biggest sig I've ever seen. WOW.

    Fans are cheap.... Is it really worth it to try to rescue them? This thing is so stiff, I almost think some of the plastic melted.

    Reviving a seized fan is not worth your time. The bearings are shot and are now useless.
    Fans are cheap and easy to replace.

    The buzzing sound is ur psu's induser
    to solve that u can put wax over the induser or save time and get a new psu if u want a good psu get an antec or enermax

    I flipped the switch on my PSU and heard a sort of SNAP sound and smelled burned circuitry.. mmm. I thought it was on and I was turning it off, but it seems that it was the other way around.

    I removed the PSU and was about to attempt testing another PSU in with the computer, but it's not compatible. The MoBo connectors aren't the same.

    I'm going to go to the local computer store tomorrow and see what they have. I'd like to get an Antec, but might settle for something less if they don't have it. Remind me to print a few pages from Amazon for price references - they include a pretty big store that's not too far from here and I'll try to get a price match.

    Got a new power supply... a few days ago. Plugged it in and the computer booted right up. It's an Antec True Power 380. Set me back around $86 (including tax) from the local computer store.

    One of the nice things about it is that it's quieter than the older PSU, and all the quiet fans I got for my computer when I was putting it together are finally paying off, the whole system is very quiet now.

    Thanks everybody for your suggestions. :thumbsup:

    Once again, Antec saves the day. Same PSU you have there saved my rig.
