Siemens S2000 systems shuts off intermittently sometime operating for 3 weeks before shutting down. I replaced 3 power supplies the PC, The Digital and the Analog. Only supply left is the AC supply or Motherboard. There are no errors in the S2000 service log, and it passes all test, however im concerned about errors in the windows error log. Looking for someone with extensive knowledge in this system software. I have photos of the errors ?
