When I left the system last night it was running fine after some Windows updates. Come in this morning and it is turned off. I pushed the power button to turn it on and got a quick amber light on the power button, the CPU and PS fans come on for about 1 second and then stop and then system never powers up. I removed/reseated memory, disconnected all cables internally and externally, tried 2 other PS (although not sure if they are compatible), tried different power outlets in UPS and directly in wall, and all get the same results. Only light on the motherboard is a solid green LED in the top right next to the rear USB ports, but the silk screening is difficult to tell what it is.
Any thoughts, suggestions, or ideas from anyone?
Thx.
