    Gateway GT5411E mobo D945GCLG1

    I just received another customer PC that powers up, fans run at full speed but it will not POST. I opened the case, blew out lots of dust an found just one cap a United Chemi-Con cap with a swollen top. The capacitor reference is C6H1, 3300uF, 6.3vdc It is a KCG series. From reading the boards, this one is flagged as a crap cap. This cap sits right next to the memory stick.

    Past experience has shown me that a PC that powers on with the fans running at full speed but will not POST is usually related to a memory issue. In this case the cap that is faulty is used to filter power to the memory sticks.

    The last board I re-caped still did not POST after the re-cap job. I found that one of the memory sticks had failed as a result of the faulty capacitor. Once that part was replaced the board POSTed with out issues.
