Right. This has me completely stumped. Firstly some context:
I have searched online and have not found someone with the same series of oddities. The fact it works elsewhere tells me it must be something to do with power or how the computer is delivering the power to the components, but why it works here with the CPU disconnected confuses me! Could there be some checks the motherboard does that are failing (poor quality power?) that when i'm in another house it passes as the power is better quality OR because i'm disconnecting the CPU it doesn't do those checks and is able to start in my house?
Has anyone had this happen before and have any ideas how to resolve? Do you think a UPS may be a good next step to debug if it is the house's power quality or grounding? Or could this be a sign of motherboard failure or grounding of the case (which was knocked when travelling to the shop?).
Really appreciate the help, i imagine this may help others who may face a similar thing in the future!

- This computer has been working for 5 years. In that time i have replaced the PSU and CPU fan (less than 3 years ago). Otherwise, i have never had any issues.
- The computer has been working fine without any issues until the past week when it was unable to be switched back on (it switched off over-night at some point)
- When i start the computer (with either the button on the motherboard or the case), a red light comes on near the 24 pin connector called JPW01. OK, so it's a power issue.
- However, here's the odd part:
- When i take out the CPU power it starts fine
- When i took it to the repair shop it started fine without any changes - just straight up worked after i brought it in, even witht he CPU power connected
- I've narrowed it down to the motherboard failing (i hope not, i don't think they make them anymore in Aus/NZ), CPU fan failing, CPU failing OR (what i suspect) power quality issues in the house. However, everything else works fine in the house...
- I've tried on different sockets and have the same issues throughout the house regardless of the circuit i am on. I've even tripped the mains breaker for a minute and flicked it back on to see if that would fix the issues.
