Hi all! I know it's an old card but I managed to grab it cheap recently for my little brother who loves playing Minecraft and a bit of Fallout/Skyrim... and so this card will be ideal for the older games for now (teamed with his E7400 Core2Duo and 4GB DDR3 Ram...)
I got it knowingly that it was faulty with the hope that I could repair it...
I've managed to track the fault down to one of the 2x 6 Pin PCI-E Power Connectors, (SEE ATTACHED IMAGE) when I plug this in it doesn't allow my machine to even try to start and so it seems it's got that much of a fault on the power circuitry that it's cutting the PC's power circuitry out too... What I've tried so far is (with my little knowledge): -
I'm getting continuity across all the pins on the socket, I'm also getting continuity right through the 2 capacitors I've marked in the image also, I have de-soldered these capacitors to see if they were the issue but the continuity remains... I've done a lot of reading regarding the Mosfets and whilst the issue really does seem to point at that being the problem, I've checked all the Mosfets (Marked in the image) with just basic Continuity from my Digital Multimeter and they all give the same reading so it doesn't seem that one of them is broken..?
(How am I supposed to be testing them? I'm getting all the same figures from them???)
1.480 from Drain to Gate (- on the Drain and + on the Gate)
Then I get continuity from Drain to Source (Multimeter beeps)
Am I doing this wrong?
Any help will be most appreciated!
Thanks, Adam.
