I put my PC to sleep and it stayed like that for about 3-4 hours. When I turned it on, there was a strange sound coming off it. I immediately turned it off and then back on and the sound went away. So I wasn't sure exactly what the source (MB, CPU, RAM, GPU, SSD, HDD) was. I am thinking of replicating the scenario so that I can check the source of the sound and if/ if not the sound will be there again.
What should I do?
