Just installed my B580 yesterday. After shutting down the PC I changed the gpu and booted the PC. At first it was not posting anything, just light and fan spinning in the PC. I pressed the restart button on my case and after a bit it showed an image and I was able to log in windows. I installed Intel software for downloading the driver and used it to get the drivers up to date. The gpu was landed correctly in task manager. I then shut down the PC to get rebar switched on. Once it was done I booted the PC and it all worked correctly. Today I went to start my PC and it didn't wanna post anything. The screen went into sleep mode. I switched the gpu and windows booted normally. I downloaded ddu and removed the old drivers. I reinstalled the B580 and it worked normally. I shutdown my PC and went away for the day. When I came back the same issue when I started my PC. No post just light and fan spinning. I tried pressing the restart button multiple times but it didn't change anything and the card doesn't wanna post anything. I am confused by this problem since it works but then doesn't. Is there any info on such a problem?
