Q: Hi, this is my first post here, happy to talk to you,
I an old P3 500, Asus P3B-F mobo, Ive used for 5 years. I recently re-post Win 98SE, . I was browsing on my desktop, I was posting some icons . and then everything got frozen . I have my computer off Ans that was the last time I saw it live. I
When the start, fans start to push, I can hear my hard drive scratch a bit and this is it., . The monitor never turns on and nothing is booting. I can not see anything.
here is what I have done / tested
Fisrt power: with a tester, I checked the voltage and it was fine
Hard disk, processor, graphics card, I tried with another, and it has changed my bios with nothing.
I jumper, unpluged the connector, pulled the battery let it sit for hours . nothing . black screen and fan noise (I mean no power from the screen to the computer)
is a sign that my motherboard burned. . but why after 5 years. This is only my battery? usually there would be at least a message telling something about my poor battery . Do you agree with my conclusion . I have on my motherboard . I change nothing I try?
thanks
Best Answer: Wow. Such a temper.
Did you try removing and reseating your RAM?
Did you try removing and reseating your Video Card?
Did you try removing and reseating all of your other add on cards?
One loose card, one loose stick of RAM, and by loose, I mean improperly seated, could cause the machine to not want to boot.
Your power supply itself could be an issue. I doubt you have a power supply tester handy though.
Yeah, sure, you could just throw it away…. in which case, email me so I can give you my address and you can ship it to me instead of throwing it in the trash….
or..
You can take it down to a local repair shop and have them take a loo at it. I mean, come on… if it is something small that is causing your problem, is it really worth getting a whole new machine? And again, if you are just on the new machine kick, I'll take the old one.
Re:Take a look at your capacitors on the motherboard. There was a period of time a few years ago when almost the entire MB industry was plagued by bad capacitors. You can often times see bad ones by the fact that they look like they have exploded internally, so instead of having a smooth cylindrical shape with flat tops, they might instead of tops that are elevated and rounded, like a hill. Or, they might show leakage at the bottom or anywhere else.
Use a magnifying glass to take a good look at them.
http://www.badcaps.net has some pics of examples of this problem.
Re:the only thing i have'nt tried swaping is my mobo and psu. I have swaped with another brandnew harddrive, videocard and even another P3 500… always end up with no signals…but agp video fan is working, harddrive scratchs, psu fan working light on my motherboard is on…there is only one green led on it which i could'nt find what it means. There is no beep…nothing strange…just no signal.
(it's not my monitor, cause i have it working right now on my other system…which everything is almost incompatible with my old one)
So after all you've said, my best guess would be to try with another PSU and then if not working again, i'll change my motherboard… since i have already tried to disconnect everything as guy mentionned.
I am looking with my neibour shop to get a PSU i'll let you know if something will bring back this thing alive….then if someone get another good idea to help
thanks folks
Re:Do you have a spare video card to try? At least do this:
Reseat all your cards and cables. I would pull them out and put them back in, to be sure.
I'm thinking a video issue, given what you've described. Does the video card have a fan built in? Is the fan working?
Re:Trouble with a tester is that it tests averages – no way you could read a voltage every 10 milliseconds.
If the power is dropping for just 20 milliseconds, you will have probs [1/50 second]. Maybe even less tolerance than that.
I personally would DISCONNECT EVERYTHING from mobo except psu/cpu+fan/case spkr/pwr switch header.
Switch on and see what happens.
If same, then you know it is either mobo/cpu/psu. – You will have to swap parts to see what is happening, unless you have a pci post card diagnostic tool to hand.- highly recommended.
If you hear beeps, then add RAM.
carry on till nothing responds.
Re:When a PSU fail…Does it still produce voltage? Cause i ve checked it with a tester, and i could read all of them ( 5v,12v,3v… on every cables)
Re:Well.. as far as computer components with finite lifetimes.. I'd have to rate mobos close to the top, under HDs and mice/keyboards (and cheap PSUs), they often do fail somewhere in that timeframe, although generally they fail gradually, as the capacitor eletrolytes dry out, and other components degrade with time. Although, board flex/connector-failure is a semi-common cause of death of well-used boards too.
I killed my BX6-r2 due to an "accident", but then the BH6 I was using for some time afterwards, running a PIII 1Ghz Coppermine, finally gave up the ghost after slowly, occasionally, flaking out. The VRMs on the BH6 were pretty severely taxed by the PIII 1Ghz chip though. No matter how much higher I boosted the volts in the BIOS, I couldn't get much above 1.65-1.7v, which is the minimum it needed to be stable.
The fact that your system failed suddenly and catastrophically, and didn't boot again, sounds like some component simply finally gave up the ghost, although it's not obvious whether it was the PSU, the mobo, or something else, although the mobo is probably highly suspect at that age. (Unless the PSU is of similar age – PSUs usually fail before mobos do, due to the higher heat that the components are exposed to.)
Re:I dont have a second PSU in my hand to check with.. but i am really confident that it works.
Do you think it could be my motherboard? Is it possible for a motherboard to just go away after 5 years of exellent work?
I have never overclocked it…
Thanks for your answers
Re:Yes, but if you have another one, try it anyway.
Re:I 've checked it already and it produce some juice…i got all the voltage necessary……..
??
Re:Welcome to the Forums
If you have another power supply available (in another computer, maybe?), try it next.
