I have an ASUS A7N8X-X motherboard that wont start up at all, when you power up the PSU the green led on the MB lights up but when you hit the power button the CPU fan starts to spin then stops. The PSU works properly on another MB, I have tried this with and without memory, HD, video card. I am wondering if someone has attempted a bios upgrade and failed? I have looked over the MB for damage and found nothing IE: bad caps etc. The CPU from this MB works properly on another MB. This is a used MB I picked up recently so I don’t know it history.
Has anyone ever jump-started a PSU while it is connected to the MB with this kind of no start problem?
