[Shamon]

Hey guys.  I've been having this problem ever since I got my Pc and it happens at least once a month. i press the power button on my pc case and it won't turn on. So I have to unplug the pc, take the CMOS out and put it back in, then if I turn on  the PC it turns on and boots up normally. I don't really know what the problem is and i hope you guys could help me out because I know there are a lot of people who are WAY smarter than me when it comes to PC's. My PC specs are 3900X with the stock cooler, RTX 2070 super from EVGA, 32 GB of G Skill Trident Z DDR4 ram, 500 GB NVME SSD and a 1 TB SSD. My motherboard is a Aorus B550 Master.

Are you making any changes to the BIOS after you get the system to POST?
