    1st mobo recap - CC KZG for Nich HN

    This HP board has CC KZG. 1000uf * 4 (8mm*20mm) total near the backplate and 1800uf (only a single cap showed psychical signs of leakage) near the CPU of 10.

    Would the Nich HN's be a good fit for replacements? I have pulled the bad (leaking) caps. The board did POST with "bad" caps.

    I tested the bad cap's capacitance with an arduino based cap meter. They were in a reasonable range with this device, 20% I came across an esr arduino meter, but don't have the parts to further test. I understand the limitation of this, the arduino esr should give good same cap to cap rating.

    ...from what I've read the 8mm*20mm seem to be the same across mfg.

    1) Is it okay to only replace a single cap in a group (we would all like in circuit measurements, but we do what we can) In my case, the 1800uf lined with the CPU?

    Thanks in advance.

    thats the input VRM. Nichi HN's are fine

    if it posts with them all bad, you can just replace the one with the worse reading, they're all in parallel so the quality of the power can only go up

    if I were you I would replace them all

      ASUS P5GC-MX motherboard recap
      by momaka
      Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
      This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

      So here is what the motherboard looked like with its original caps:

      Mobo MSI B550-A PRO password popup
      by Cerberuska
      Hello guys,
      I have interesting problem. My MoBo MSI running on Ryzen 7 w/o graphics just good. I swapped to Ryzen 5 5600G and on the boot I stuck with screen on picture. Enter Password. I checked BIOS setting with Ryzen 7, no security is enabled, BIOS password or TPM.
      BIOS I updated to last one.
      any suggestions?
      And same thing for two different 5600G, and yes, MoBo supposed to support it.
      Thank you...

      Dell G3 17 3779 - no display after mobo replacement
      by mrsith
      Hi guys,

      I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.

      Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,...

      no-name Radeon 9600 XT recap and cooler
      by momaka
      I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.

      This one was actually suggested to me by ChaosLegionnaire....

      Corsair cx600 psu & ASRock B450Pro4 mobo wont start
      by Ibod
      HI I have a PC using a Corsair cx600 psu & ASRock B450 Pro4 mother board that won't power on after a shutdown (replaced a dead drive in a raid array) Not the boot drive.

      With most things unplugged, including the 24 pin ATX connector, but not the ATX12v to cpu, I have +5.01V on the +5vsb pin 9 from the PSU. When I plug the 24 pin back in to the mobo, the +5vsb fluctuates between 1.1v & 1.9v.

      Not sure where to go from here ?

      Is the PSU at fault or is the mobo causing the problem

      Look forward to any help :-)

      If I plug the 24...
