Try Re-seating the card that connects the ISA slot from the computer mother board to the I/O Dpram card. It may be worth checking the ISA card for bad solder joints. The computer mother board could be going bad. Check for vented electrolytic caps. Ho

In those cases where we have a 3.2mm thick, 16-layer board with several GND layers, do we still need ground connection to each and every layer (with thermal relief) or, skip part of the ground patterns? Will it help soldeing rising. I can't reach mor
