Came home to find out my son kicked a soccer ball into the front of my PC. Now it won't start.
It'll turn on for a few seconds, then 1-Long Beep 4-Short Beeps and power down.
I've disconnected the hard drive, DVD, taken out the sound card and video card. Same thing.
I thought it might be the reset button on the front, disconnected it and same thing.
I'm d-loading the MB manual to see what the MB codes mean. Hopefully something I can fix.

here's a guide that's helped me before:

check to make sure your CPU fan is still working, if yes, then check the power supply to make sure thats still working if yes, then Kick your Kid and see if he is still working.
-
Discon'd everything. Fans all work, at least for about 5 seconds.
I took all RAM out and same thing. Checked both the Power and Reset switches and both seem to work fine. I even discon'd the front stuff (USB, IEEE, MIC) and same thing.
Waiting to post on ABITs forum.

ya I was just about to say one long and 3 shorts is a memory problem.
did you put them back in order? I dunno how old or new your computer is.. make sure you put the memory in the first slot. if you have more than two then, add the next one to the next slot. sorry I duno how much you know about computers my knowledge is very basic.
-
Well, remember, this has been working great for a long while.
I'll swap the 1G chips around and see if it's a change.
I'll also try my son's PS connected to my MB to rule out the PS. If it's MB problem then I'll have to replace it.
-
Read two things....
First was that 1 long 4 short means a fan RPM, so I'll discon the fans and ensure they are all connected up right. Second was Power Supply, so I'll try this PC's PS and see if it works.
-
Well your definitally on the right track i tseems, hopefully you can get it resolved otherwise you will just have to let me spec out a new computer for you ;)
-
Well if it isn't the PS or the FANS then I'll probably be looking for another MB.
The CPU I have is an AMD 3700+ (San Diego)
Motherboard is an ABIT AN8 32X
RAM is Corsair PC3200 DDR (2?) Premium (1G x 2)
OCZ EL DDR PC-3200 Dual Channel Platinum
I'd really like to go cheap, so a MB that could support the CPU (939) and ram would be what I'd be looking for.
I'm hopeful that it'll turn out to be a power supply or fan, even though I have a really good PS now. I have NO PROBLEM with getting another one.
-
Yikes, not much made in the 939 socket anymore as that is 3 generations old for AMD.
-
Couldnt find anything on newegg so I checked out pricewatch and they have a couple of boards. Not a whole lot to choose from especially if you have a video card in it as your Abit is a pci express board and alot of the socket 939s on the following link are AGP, some don't even support operation in dual channel :(
Let me know what you find out and I will look at them all in more depth to make sure you get what you need ;)

Crap forgot the link, here it is.

Have you checked to see if it jamed the switch in the on position? Most are momentary switches and if stuck could cause this problem.

One of the first things I thought it might be. I actually discon'd each switch and used them one at a time on the Power header. Both worked the same, powered the pc on for 5 seconds, 1 long 4 short beeps and power off.
Right now is just a tight time of the year, son's b-day is actually today (the ONLY thing that kept him out of trouble for all this), and of course X-Mas coming up. Just don't have the liquid assets to spend on a new MB+CPU+FAN+RAM.
-
Did you swap that power supply yet?
-
Are the switches, by chance connected too a small circuit board? If so i'ld recomend metering the switches if you know how. The area of impact is usually where the problem is found, if not that, did it fall or was it just a hard hit that jostled the chasis?
-
I'll do the PS later this evening after everyone's asleep. The switches are just push button -> header on the mother board, the only circuit board in the front is for the audio, and I discon'd it early on.
After everyone's out, I'll try the fans. Putting a known good fan on the CPU FAN header and see if it's an RPM issue. I kinda doubt that. Then I'll open up this PC and just plug in my MB to this PS and see if it's my PS that failed.
The impact might have jarred something loose in the PS. I remember it going into alarm a couple times in the middle of the night, but it reset just fine each time. It could be that the PS was faulting then and the soccer ball just finished the job.
-
Fans were no change.
PS was no change.
Looks like I'll be needing a new MB for sure, and hopefully I can find a 939, else I'll have to get a full array of gear.
-
I just bought a spare 939 motherboard at www.geeks.com for $29.99

I goto the Geeks here just because I can drive to Oceanside to pick stuff up. ;)

Well.... as a last ditch, and to check a suspicion I had...
I pulled the MB. I knew I'd have to anyways and with everything disconnected it was a snap.
I put it on a cardboard box and took out the power switch, connected it and the power supply and fired it up.
It ran through a ton of numbers NOT STOPPING AND BEEPING!
I had a last hunch that maybe the shock to the case moved the MB enough to short/ground something. I noticed that all the standoffs except one were loose.
I'll get some small rubber washers tomorrow and isolate the standoffs. I also have to make sure the back side isn't coming in contact with anything there. Then I'll fire it back up in the case and see what happens.
-
Hmm, methinks desperation has set in. :)
-
Typing this from my PC.
I put a double level of electrical tape on all the standoffs and put a strip of tape along the back edge (where the MB is close to the back) just in case there was something touching there. I also taped the bottom side of the metal "frame" where the USB, sound, LAN stuff goes.
Put the MB back in and it ran through a BUNCH of codes, not stopping and beeping at the beginning.
Reassembled everything, rerouted some stuff, taped some stuff together, and put it all back in and it's working great.
I figure the MB slipped enough to short against the back someplace. I don't think it's a standoff, but to be sure I taped them anyways. Why do they make metal standoffs anyways?
SO... dodged a bullet this time. I need to keep my eyes open on a new MB/CPU/FAN/RAM set though, never know when the next GOAL might go astray. :P
-
Glad you got it fixed, at least you don't have to buy something new unexpectedly this time ;)
-
Wow, sometimes desperate measures are required! You did miss the golden excuse for a new computer, though! I woulda taken that one all the way to the bank. heh.
-
The metal standoffs are for grounding of cetain points on the MB. It does not need all metal standoffs just certain ones, but the manufacturer instead of making a few metal and a few plastic makes all them the same :)
