PC working fine last night when it was turned off. This morning, fans come on and the little blue LED indicating disk activity turns on, but nothing else. Monitor acts as if in stand-by (LED blinks slowly). Turned PC off (hard off) and on, seemed like it was going to start, then shut down, then came back up on its own as just described.
My first guess (hope) is that it is power supply, and the supply-good signal is not getting sent.
Do you agree that is the most probable fault? What can I easily test to pin-point that fault? I hate blindly swapping components, as that can get expensive.
What are the second and third most probable faults? All heat sinks, including the CPU seem to be in place. The machine is about 4 years old, but has had very low usage until the past 2 weeks when it became my primary PC at the farm. In other words, this is the first time it has been left on continuously throughout most of the day.
PC was built from decent components from a local DIY PC center on Ohio (MicroCenter). It has an Asus MoBo P5QC, Intel CPU, power supply is a "Silencer" from PC Power and Cooling (OCZ Group),
disks are WD, display is NVIDIA Quadro (installed to run SolidWorks), memory is PC2 8500 (also OCZ) .
Thanks, John
