i have some new groundig problems when i touch floppydrive removing disk. this is new since i have had this pc out of the case lying freely.
maybe there are some interconnections because i use a multiplexer(several pcs, one monitor etc.)
floppy lies on cd-rom-drive seperated with rubber.
maybe i must disconnect the cable and reconnect. on my main pc-which now has a rubber-base on the table, i tried to use different grounding solutions without any clear answer. at the moment i have no groundig at all on pc1. i tried out groundig the board to the supply, ps to the heating(metallic surface), all kind of versions without success.the problem discussed above concerns pc2 without rubber-surface only sort of plastic-material around wooden-plate, the material with air-bubbles inside used in packagings.
