My PC which is also recently built and pretty new, at first had faulty RAM which caused many issues. After replacing that it's been running fine however, I never turn my PC off instead I put it to sleep and boot in from that each time I use it. Recently, about once every few days my PC will randomly wake up from Sleep Mode by itself without any input and post no signal on my monitor. My keyboard and mouse also don't light up like they usually do when the pc turns on. Clicking or typing along with any input does nothing to help, hard resetting it with the power button just restarts the issue with the PC turning back on to no response with the CPU light on the motherboard going red. The only fix is to take out the CMOS battery for a few hours at a time to clear the CMOS which then clears the issue. I turned off the XMP profile and overclock to see if that was the issue however it still persists regardless of me doing that. I have no idea what could be causing my pc to do this and whether its software or a hardware error.
