Hello, I was wondering if I could get a bit of help with my motherboard.
I've got an issue extremely similar to this one here, except that my CPU_LED won't turn off.
My motherboard is a ASUS Crosshair V Formula AM3+ AMD 990FX, which I believe is running the default BIOS 1102. It was purchased through Newegg, arrived undamaged, was installed as I was grounded, and was installed as guided.
The motherboard appears to be working normally at first glance, as it powers all of the fans normally, lights up, and is startable using the power button on the case's front I/O. However, when I power it on, the red CPU_LED light remains on and nothing is displayed to my monitor no matter what I do.
The red CPU_LED light remains on even after I remove or reposition the CPU, empty all but one DIMM slot, remove the GPU, reset the CMOS, turn ROG Connect on/off, and disconnect my hard drive. All of the pins on the CPU are unbent, the board's LEDs indicate that everything is receiving normal voltage, and everything on the board appears normal.
This is a brand new build, so I can't swap any pieces out to determine other issues which could cause this problem, but the issue seems to me to definitely be the board itself.
If there's anything I could do to avoid having to submit an RMA, that would be wonderful. I want to get this working ASAP.
Here are my build's specs-
