I have MSI Z270 Gaming M6 AC, MSI R9 290 Gaming, CORSAIR DDR4 2133MHZ (8X2),INTEL I5 7600K. My computer doesn't post anything on the screen and the error code goes between 62,30,31,A2 and like that i think the 30,31's are the temperature because the pc is opening but doesn't post. I solve this solution by shutting down completely or using it with 1 ram slots. But it gets worse and worse and I have to do this pretty much everyday. Its like if I don't open it a single day, the next day it doesn't post. Thank you for your answers.
