Pc has been running fine for about 18 months. Left it on this morning, in the evening found it shut down and turn on.

When I turn the PSU on, motherboard lights up (white light blinking). I hear a click when I press the power button on the case but nothing helps. Dr. debug lights are off. I haven't made any change in the PC or even moved it. Any suggestions?

Appreciate any help. thanks

Dear Drpencilcase,

Thank you for posting your query to the ASRock forum.

Please try the suggestions below:
1. Please try to clear the CMOS.
2. Please install only one RAM to a different slots and try.
3. Please try with a different power supply, RAM, CPU.

With thanks,
