Basically, whenever the workstation needs to be restarted, the monitors will blink in power saving mode for 10+ minutes and then suddenly, there's the splash screen and we're up and running without any sort of issues.
I've tried various monitors and cables, ran complete hardware diagnostics, reset bios back to default. updated all drivers and bios, reviewed and applied the appropriate solutions to any and all event log error ids. Not sure where to go from here.
