We need some help with a workstation at one of our outside bars. It began by slowing down considerably until it would freeze up. It now will boot to contrast up/contrast down screen 90% of the time. If we can get it to boot completely it'll last only a few minutes until it slows and freezes again. We've ran a new wire out to it, swapped workstations, switched bar drawers, printers, and wires, but to no avail. We have the Micros POS 8700 and all other workstations and bar terminals inside the restaurant, and at the outside tiki bar are operational. It seems more like a problem with the location. Sometimes when stopping the workstation and restarting from our micros pc in the office we get a system closed message at the contrast up/contrast down screen on the workstation. Our local micros tech is stumped as well. Any help regarding this issue would be greatly appreciated.
