Still No Banana After Recapping

[dubois928]

Hey all. I have a FIC AM35 motherboard that had bad 1000uf 10v caps. I replaced all eleven with chemi-cons and I am still getting the same exact BSOD I was getting before the recapping. What could be wrong here? Weak contacts?

Thanks,
Ken

Re: Still No Banana After Recapping

Did you replace the _other_ caps that were 470uF and higher?

Re: Still No Banana After Recapping

below low is really just some possible trouble areas you can explore or check

Yes recheck your work...is a good option
have you done recapping before? (know how to solder etc or is this a first attempt)
did you reset the Cmos?

were you reinstalling windows or are you just trying to boot off the old install
Depending window can be corrupted from bad caps.

Perhaps try booting in safe mode.

Sound like you have some knowledge
(as in you must have done some research on it at lest)
to know your caps were Bad

What specific type series of caps did you replace with?
(you probably used the right ones but posting would help people know for sure)

Another possibility is the PSU try switching for a known working one.


BSOD does not necessarily mean badcaps

write down those "gobbly gook" numbers and either post or google them

This should hopefully give you an area to look at

To me

same "exact" BSOD

before and after the recap points more to the same exact issue.
(granted it my just relate to very similar issue with the same area)

lastly if the MB had bad caps (depending and I dont know the MB) it is possible for other damaged to have occurred from them too

Memory (Ram) for instance has been known to be damaged from them.

Was the system just freezzing or rebooting somewhat randomly before this
or was it this "exact BSOD" that sent on the quest to fix the problem and you found badcaps?

did you change update anything before the BSOD?

(chipsets have been known to die and VIA chip sets I believe can be problematic with drivers etc)

sounds like I am asking heaps of questions but there can be lots of area were things can go wrong so the more detailed information is can sometimes nail a fault quicker.

Hope this is of some help Ken and welcome too

Cheers

Re: Still No Banana After Recapping

I've had 2 of these boards. The 2nd one was fairly recent and had bad 1000uF caps. The 3300uF caps were Sanyos, surprisingly. That board is still no POST after recap. I noticed the clock generator was running hotter than anything else, so maybe that was it.

The first one was a long time ago, it had bad 3300uF Vcore caps. That one ran after recap (I also did the 1000's) but only at 100MHz bus, and even then it has stability problems. The voltages were pretty bad as I recall. I noticed the stability improved when I blew a fan on the mosfets. I'd like to try swapping the mosfets sometime but I don't know when I'll want to take the time. I also may have ruined that one, I wasn't very good at soldering back then.

On both of my boards, I noticed that the busted caps were widespread. It wasn't just a few caps here and there. It was like something catastrophic happened... like an eMachines PSU exploded or something.

So for whatever it's worth, we're a combined 0/3 on AM35 boards. Maybe it's a coincidence, or maybe these boards just don't survive cap failures very well.

How are your voltages?

Re: Still No Banana After Recapping

This the MB here ?
Just so I know what your talking about


Thanks for the feedback gdement, really hoping for Ken,s sake its not a damaged MB

Emachines I have noticed a few posts on around the forums
(speaking of that 754 post here )
0/3 isn't a hopeful sign thought

be interesting to see what our regulars here think of the situation
those that do it day in day out.

Re: Still No Banana After Recapping

i see a ton of the am37 killed by bestec so if these came from evilmachines they might have had both feet in the grave before you started.
of the ones that make it all have s.i. 1000@6.3 popped like they hatched.

Re: Still No Banana After Recapping

Thanks everyone! I'll try and answer some of your questions.

+Did you replace the other caps that were 470uF and higher?
-No, the other caps seemed fine, the 1000uf ones were the only ones leaking or bulging.

+Have you done recapping before?
-No, this is a first attempt.

+Did you reset the Cmos?
-There was no battery in the motherboard for quite some time before and after the recapping.

+Were you reinstalling windows or are you just trying to boot off the old install?
-I actually just grabbed a hard drive that I had pulled out of another computer. Driver conflicts?

+Perhaps try booting in safe mode.
-Did not work.

+Sounds like you have some knowledge to know your caps were Bad.
-I have been researching the topic and reading tutorials for quite a while.

+What specific type series of caps did you replace with?
-The original caps said "S.I." on them. The new caps are chemi-con kzg series low-esr. Both are 105+ degrees tolerable. Bought new caps here .

+Another possibility is the PSU try switching for a known working one.
-I'm pretty sure the PSU works.

+Memory (Ram) for instance has been known to be damaged from them.
-I'll try some new ram later.

+Was the system just freezing or rebooting somewhat randomly before this
or was it this "exact BSOD" that sent on the quest to fix the problem and you found badcaps?
-Actually, I had was stripping an older computer for parts and I noticed that the motherboard had bad caps so I thought I would replace them and build a new computer out of it. I tested the board before the recapping and got a BSOD. After I recapped it, I tested it again with the same parts and got the same BSOD.

+This the MB here?
-Yes.

The other capacitors on the board are 6.3v 3300uf rubycon mbz.

Thanks,
Ken

That's your BSOD right there. Happens 9/10 times when swapping drives without reinstalling windows.

Re: Still No Banana After Recapping

BSOD 0x7B is storage driver problem.

Another problem is when a different chipset is on the installed Windows version, vs. the actual chipset in the board. For example, replacing a dead SiS chipset board with an Intel board will BSOD every time.

Re: Still No Banana After Recapping

get the ubcd.
http://www.ultimatebootcd.com/download.html
run memtest,mprime.
if it passes both run insert which is a live distro on the cd.
any board that passes those tests and gets to the insert desktop is 99.99999% ok.

Re: Still No Banana After Recapping

Gee go a way for a few hours and look what happens "thanks Guys"

Keep use posted how you go on the above advice

Re: Still No Banana After Recapping

You could try booting an operating system from CD/DVD such as Kanotix or Knoppix they are free to d/load (google them). This would rule out if its the hard drive or operating system - if they run ok, its not your mobo thats at fault, if they crash lots, it is!

Re: Still No Banana After Recapping

The Bestec 250 watt some emachines used back then is a known chipset blower.

Dear Friend,
My past experience tells to replace all the capacitors of your motherboard instead of replacing only those seen to have problem.

Re: Still No Banana After Recapping

Dear Friend,
After replacing the majority of the capacitors of this mainboard, it was found to reboot once for about two months. This persist until all the remaining capacitors were replaced.
