My pc won't boot when I press the power button, no fans are spinning but my rgb mouse is lighting up. I had been using my system the previous night and I kind of fell asleep and left the system on, so when I woke up the next morning I didn't bother to turn it off I just kept using it so in all the system kept running for about 16 hours consistently, then a power outage happened and my system went off. When I tried to turn it on after it won't boot, so I bought a new power supply and installed it, however it still won't boot. Is it possible that it may be the motherboard? I don't want to go out and buy another part without being certain. Can you guys give some advice? And thank you in advance for any help.
