I recently bought a new set of hardware (except PSU, which is from an old rig that had not a single issue in its lifetime), but every time I turn the computer on the CPU fan twitches, the PSU clicks, and the rig powers down.
The motherboard power light LED is on, so the board is getting power, but whenever I power the rig itself the CPU LED flashes for a split second, the CPU fan attempts to spin for a split second, and then the PSU clicks and the rig powers down. The motherboard LED stays on, but using the power button has no subsequent effect unless I turn the entire unit off at the plug.
I have spent the past few hours reading over various websites and forums for assistance but nothing I have tried appears to work:
- I have tried using a different (more powerful) PSU. No effect.
- I have changed the standoff positions and even had the motherboard resting on a non-conductive material (just in case there was a short in the case).
- I have tried with various sticks of RAM in the various motherboard slots.
- I have re-pasted the CPU in case it wasn't connected property to the heatsink.
- I have checked every connection to ensure there aren't any broken or disconnected pins (including CPU and all motherboard connections).
- I have run the system on the bare minimum (just a CPU and its fan and a single stick of RAM) in case the PSU wasn't providing enough power.
- I have shorted the power-up manually in case it was an issue with the power button.
- CMOS reset via jumper.
The whole computer was put together with utmost care, so I highly doubt I've damaged a component myself. Much of the advice online suggests a dead motherboard but I really don't want to have to provide proof and send it back. Does anybody have a suggestion that might aid in troubleshooting?
Rig specs:
PSU: 750w (24A on 12V1 and 12V2, 30A on 3.3V, 33A on 5V).
Motherboard: Asus M5A97 PRO 970 Socket AM3+ 8 Channel HD Audio ATX
CPU: AMD FX-4 4100 Black Edition 4 Core 3.6Ghz Socket AM3+ 8MB L3 Cache
RAM: Corsair XMS3 DDR3 1333MHz 4x4GB
