Today after I finished playing I put my pc on sleep mode like I usually do and then about 10min later it turned on by itself so I put it on sleep mode again and the same thing happened it turned on but after I turned it off the 2nd time it did not turn back on but then I realised it logged me out of steam and I never log out of steam on my pc anyone know what this could be?
