I bought the motherboard in August with all the other components. Only, the GTX1060 was from the previous system. The problem I had since the beginning, I just did not notice because the BIOS 3601 led to idle crashes. Since BIOS 3801, the idle crashes no longer occurred, but regularly I can not turn on the system. I have to turn off the power supply every time, wait 30 seconds and then the PC starts. Exactly as many describe it here in the thread.
BIOS 3601 > 3801= always the same behavior.
Power supply replaced = always the same behavior.
3 different RAM kits tested = always the same behavior.
1060 to 3080Ti = always the same behavior.
CMOS reset = always the same behavior.
BIOS set to default = always the same behavior.
CPU swap to 3700x = did not occur but could only test for 20h
My CPU 5950x in a MSI B450-A PRO MAX B450 = ran 9x weeks without problems.
During the 9 weeks the board was at ASUS and came back with "In the responsible service center the described error could not be reproduced.
Now on the weekend, I installed the ASUS again and the problem is back.
After I have now read everything here and tested everything that was suggested, this setting seems to fix the startup problem but at the expense of WakeOnLAN which is not a solution for me! (no long term experience yet, only about 2x days and 3x shutdowns/restarts) enabled S4 + S5
@ ASUS, The problem is very unpleasant and is in no relation to the value of the motherboard of over 450Euro. A 60Euro motherboard from MSI does not have this problem and yes it is slower but it is reliable. When will the problem be solved?
