Hi, there
Recently, I built my new pc with the MAG Z690 TOMAHAWK WIFI DDR4 mb about 6 months ago and it has been working perfectly till now. Yesterday I was using it all afternoon, took a break for dinner, came back and it would not wake up - monitors blank (normally have images showing after timeout). I rebooted, nothing would happen. Checking the MB, all the fans came on, led strip on RAM lit up, BIOS debug LED flashed red, then the RAM debug LED flashed yellow, and then nothing. The white VGA debug LED never comes on, green BOOT degub led never comes on, and there it sits, nothing happens.
I have tried clearing the CMOS, no change. Changed the video card, no change. Unplugged everything, took out RAM, booted, got the expected yellow debug led light on and beeping because of no ram. Put RAM back in, yellow debug light went on and off as expected, but then hung. Also removed the GPU, booted, expected to get the white debug LED light on, but no, nothing. And when it hangs there are no debug LEDs on.
Any thoughts? As I said, this has all been working great for 6 months.
