    VIA P4PA-UL Bad Caps

    Hey folks, I bought the subject mentioned mobo about a year and a half ago. It was fine for a while, but then it started rebooting itself. I thought it may be a voltage issue so I turned the voltage down. But it didn't make any difference.

    Then about two months ago it wouldn't do a proper restart. Sometimes it wouldn't restart at all, other time it would start the process at post but then it would just sit there spinning the hard-drive, at which point i'd have to hit my reset switch to boot it properly.

    Then just last month I looked at my mobo and discovered two bulged and leaking capacitors right next to the CPU. So I imediately dismantled my machine and i've been searching for new/better capacitors to replace them with ever since, believe me, around here they're hard to find.

    Anyway, I was just wondering if the caps on my board have been blacklisted. They are manufactured by a company called GSC, the whole mobo uses this companies caps.

    GSC is a very commonly known crappy cap! MANY companies used them, and I'm sure that now they wish they didn't. If you plan to recap your board, replace all caps 680uF and up.

      Yeah, the two that went were 3300uF. I'm just gonna bye a new board though, since the P4PA is a pretty old board now. I'll hang onto it though for a future project or something.

      I just wanted to know if GSC was blacklisted. Thanks for the help.

        Me too
        Not only it's full of bad caps (GSC)

        Someone tried to replace some of them with totally unsuitable caps (1500uF/16V -> 1000uF/10V on 12V, 3300uF/6.3V -> 1000uF/10V...)

        Someone also scratched the PCB, breaking 3 traces

        And even inserted memory backwards, destroying this diode


        After fixing the traces and replacing the diode and caps, it works. Sometimes - depending on CPU heatsink movement. There's probably a bad solder joint under the CPU socket (SMD)...
