Hello! I'm new here forgive me but I have a weird problem with my PC. It all started when I had just finished building my new PC yesterday and tried to turn it on. Immediately as I turned on the PSU the fans in the PC lit up and were spinning very slowly. The AIO pump was audible too but the system wasn't running. I then turned on the PC with the power button and the fans started spinning faster and pc booted to the bios and I installed windows normally. After that however I noticed if I tried to turn off the PC either from windows or the power button it would start up right after again. It has been like that ever since and I cannot figure out why it won't shut off and why do the fans light up and spin slowly just from turning on the PSU.
