So after welding the new electrolytic capacitors, I tried to see if one of the motherboards works.

As we will see, the replacement work was successful, for the moment I have not completed the work on the ASUS P4SDX, while the BIOSTAR is waiting to be verified and subsequently tested.

But what motherboard is on the bench?

An Intel D845GEBV2, with CPU P4 2400/533, in this board I replaced three swollen electrolytic capacitors, with three others the same but from Nichicon, definitely better than the ones that were installed.

As soon as I started the power supply, the motherboard started without pressing the power button, soon enough the sequence of post codes stopped, I think the RAM was not compatible, however without RAM the PC beeps, a sign that both the BIOS and the CPU are working.

I summarize briefly, avoiding commenting on the various steps and startup attempts, after many attempts, I found a perfect combination that made the PC work, but unfortunately there remained a tendency of the PC to crash quite soon, so I decide to connect the usual IDE CF adapter with DOS, to run the bench, after some startup attempts, a fatal error (DMA) appeared, after that screen, nothing appeared on video anymore, and the post codes stop quite soon, in short, try and try again, but nothing no progress, and since before it was practically unusable though Starting out, I decided not to waste any more time, and I brought it back among the motherboards to be repaired.
