    Hercules 3D Prophet II MX 32MB

    I just fixed this video card which had been in my junk pile for a few months. Symptoms were hugely corrupted video even in BIOS text mode when cold, flashing coloured characters over the whole screen. This got gradually better after the card warmed up, until it was almost usable. Eventually the image still flickered even when hot, and I thought it was dead, so junk piled it. I tried to get it working today because I need a video card, and just by chance really I changed the 3 Wendell Electrolytics (680uf, 16v) on the card. Image was rock stable and card worked from cold. Once I'd fixed the damaged PCB traces I clumsied with the soldering iron, the card works like new and I'm very chuffed! These caps had no external signs of damage at all. The card had been in use 24/7 for about 2 and a half years. If it wasn't for this forum that card would certainly have been chucked. Thanks.

          I will post pics if u like, maybe not for a week or so as the graphics card is in my work system, and I'll have to find some time when it's not doing something! Card is still working great, with a really nice picture.

              Plz, I live in a poor country and I cannot buy another card, that might be funny, but i need to fix this card.

              Well, almost exactly symptoms in my Hercules Prophet II mx400 (exactly the same same one), and those 3 "big" wendells just looks like new, I'm gonna change them, but guys, will you change all the caps of the card? the others ones are little, but all are Wendell :

              Will destroy the card using a little bigger (30%+ uf) replacement? I cannot find so little caps.

              THANKS A LOT

                  The smaller ones will be probably OK - so replace the big ones first and test if that helped.

                              by Christos Tsiligiannis
                              Hello to the forum.

                              My name is Christos, I am new to the forum here and i am posting from Greece.

                              So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

                              To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

                              So i tried asking for a schematic from the company and they would not give me one. Instead they...

                              Graphics Card mounting frame
                              by Kemer
                              Hello, I removed the graphics card from my laptop and I want to heat it in the oven. What I want to ask is, is it okay to heat the card without removing the metal mounting frame on it?

                              As you can see in the photo, there is a plastic (black) gasket between the metal frame and the card. It sticks the frame tightly to the card.

                              I previously removed the metal frame while heating it, but it is quite difficult to separate it from the surface it is attached to. If there is no problem, I do not want to remove it.

                              What worries me right now is the possibility that...

                              EVGA Nu Audio Sound Card - Not Working
                              by FZG
                              I have an EVGA Nu Audio sound card that is not working properly and I need some help diagnosing the fault (preferably by someone who owns this card and is willing to take some measurements).

                              The card sort of powers up (LED lights are coming on and the relais is clicking, some voltages are present) but it is not detected in Windows. I tried installing in two different PCs and tried several driver versions but the card was never detected anyway. So I thought this is probably not a driver / software-issue and then disassembled the card to take some measurements.

                              I found...

                              Gigabyte Aorus 1080ti - card not initialising
                              by benwaterson
                              Hi there.

                              Have searched various forums but haven't come across the exact issue I am having.

                              Bought the 1080ti with a fault (randomly shutting down, black screen , fans full speed etc). Previous owner had replaced thermal pads but many were too thick on inspection.

                              I tested the card in windows, all loaded up ok. Put some load on the card and it crashed. GPU was reporting 92 degrees C at the time.

                              Switched the stock cooler out for an AIO water cooler from my 1080 FE, booted the card back up - temps were much better and allowed some load to be applied...
