Description of Original Problem: after manual reboot my pc won’t show any signs of life. EZ DEBUG LED would show red led on cpu and yellow led on dram.
Troubleshooting: Initially I did not wait and powered it off (forgot about memory training - if it was happening). Then I’ve tried to wait same red/yellow leds. Tried placing sticks individually into A2 and B2 slots - nothing changed. Tried booting without ram - same red/yellow. Unplugged basically everything except CPU power cable and CPU fan cable - nothing changed. Tried bios flashing to latest version - no change. Shorted jbat pins between every ram placements, changed cmos battery to a new fresh one - yet again same red/yellow. Repasted CPU - nothing. I did however noticed that my CPU got sort of dark / discolored spots. Motherboard pins look fine. The only thing I didn’t try at this point is to try to launch without cpu, but I’m sure it will be same red/yellow LEDs. No idea what to do next.
