If the fan in the PSU is AC powered, rather than DC, then the fan is still going to turn. Is the +5V present ?I insert the card into the middle ISA slot with no CF card and I no longer get the beeps, nor does it do anything else, but it is not shorting as the fan is still going.
I agree. And if the poor socket-pin-to-solder-pad alignment is not the problem cause, it may be a problem down the track.From that picture I wouldn't be surprised if you've got a short between pins on the CF socket.
With the camera at this angle the soldering and alignment looks good.Uhmm, well I thought I had done quite well with the soldering, perhaps the camera wasn't showing the pads clearly so I took some magnifier/microscope pictures. Perhaps those with better eyes than I now have can see an issue. I did resolder the left most pin25 and clearly not a great job, but it is nc and not shorted. I have checked for shorts,not easy and can't find any. About to go and check the 5v and get the scope out. Thanks for showing interest, it's really appreciated. Oh and the fan is dc.
