My PC randomly wakes up from sleep mode to no signal and no input affects it. The keyboard and mouse don’t light up as they do usually during use and nothing has any impact on it’s functionally. When I turn it off with the power button and turn it back on the same issue persists. While this happens the CPU light on the motherboard also turns on red. This CPU and GPU were previously in an older pc and worked fine so I can rule them out. The RAM is also replaced and working fine. I tried a different CPU after turning off my PC to test if it’s that but the same process still happens. The only way to boot the PC is to take the graphics card out along with the CMOS battery, unattach the power supply from the power cord and leave the pc for a few hours, then putting it back together it manages to boot. However, as soon as it’s put into sleep or turned off the same issue persists and cycle repeats. I suspect it’s either the motherboard or power supply, which would be more likely?
