    Do I Have Bad Caps?

    Hello, I'm new to this site and have found much of the material to be very informative. I came across two threads which were particularly interesting: 'Only old boards have badcaps....Right?' and 'Intel D865GBF has bad caps'. The reason for my search is because my primary computer (I'm on my wife's now) has given up working.

    Here's the story:

    (apologies for the large images--I'd specify a max-size if I knew how)


    Initially, I got a STOP: c000021a with winlogon, and after restarting, was given a Stop: c0000221 checksum failed on mpr.dll. At this point, I ran DFT,Memtest and both utilities reported no problems with either of my hdds or RAM. 'Last known good config' did nothing, though I was able to get into safe mode.

    I expanded the mpr.dll file from the XP setup disk and checked the event viewer. Nothing out of the ordinary as far as errors, but the most recent events posted were dated 2038 (or some outrageous date). I don't recall having changed the Year in Date and time properties to "12006", but that's what it had stored.

    After rebooting again and still running into the stop on mpr.dll, I decided it was time for a repair install. I restarted, but was given an error message about the cmos checksum failing. I shut the computer off, shut off the power supply and tested the cmos battery, which gave a reading of ~3V-- no problems there.

    After putting the battery back in, flipping the psu switch and turning the PC on, it gets no video. The keyboard also seems to be nonresponsive (hitting caps doesn't toggle the led). I put one of my monitors on the onboard vga port in the event bios defaults were restored, but no luck.

    I powered off the system again and upon further inspection, noticed some caps that were bulging.









    I have a few reasons I'm seeking the lowest cost solution that are not particularly of self-interest (see: family). I saw Intel offers a 3-year warranty on their boards, though I believe I'm just outside that window.

    My question: Are these caps causing the problem? I know it can't be said for sure, but what do you think?

    I appreciate any input offered.

    TIA

    yup those HN(M) are bad.
    try outside warranty replacement with intel they are aware of this problem. you will have to be pushy though.

    dont bother any more troubleshooting until the board or those caps are replaced

      Thanks for the advice.

      I was a little wary of continuing any troubleshooting as I've seen some of the terrifying images from exploded caps here, ie This is Why You NEVER Ignore Bad Capacitors!

      I'll see what Intel can do and post a follow-up.

          Classic case of bad caps. Shoot me a PM if you want it recapped.

            Big Pope: Yep, we've got the same caps. Our boards look very similar as well--the d865 series.

            Topcat: I appreciate the offer. I will definitely take you up on it if Intel shafts me, as I don't trust my soldering experience to something so important.

            I'm trying to get through to Intel by email and will give them a few more days for a non-automated response.

              Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
              by momaka
              I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

              For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

              https://www.badcaps.net/filedata/fetch?id=3591772

              It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

              Heathkit IO-4205 Power Supply Caps
              by eryjus
              Hello,

              First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

              I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

              I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

              Identifying caps on an old Zoom 9000
              by Paxman_Swede
              Hello!

              I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

              The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

              I have studied the board and...

              Help with switching power supply caps
              by captain150
              I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
              I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

              Gigabyte GA-6OXT :: caps question
              by Foetuss
              Good evening

              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

              But I was also suprised about the bigger boys, which are 330µF 25V.
              Could it be they used 25V caps because they were cheaper / available at that time?...
