Wasn't sure where to ask this general question. My computer is a basic box type machine, relatively new, windows 8 I do believe. I have screensaver setting completely off.
Every few days, sometimes more, sometimes less, the computer freezes up. Once in awhile I go into the shop and the machine <syil x5> spindle is running but it's not in motion and the computer is not locked up but will not stop or control the machine in any way. I have to turn off machine, unplug it and then reboot the computer. More often though, the machine will be spinning and not moving and possibly has even finished it's task, but the computer is frozen up. Might go for 2 days, might go for 5 days, I've had it freeze up in only several hours or less but that's less often. I can't figure out why the computer locks up or loses signal with the machine. I did try changing the parrallel cable, and I also tried doing a defrag on the computer but the defrag was at 0% so it wouldn't even do it..no doubt since the computer only is used to run the mill.
