Pc shutting down weirdly!

[FranoM]

A month ago i installed a ssd in my pc as a boot drive. So i had an hdd and ssd. Everything was fine untill i needed to reinstall windows again. After the reinstall my pc turning off time became around 5 times longer. The windows shuts down fast ( in 4 seconds or so) but the actual pc stays on for another half a minute ( fans spunning, lights working, power button lit). When i restart windows it works fine (windows turns off, than it starts to boot up again emidietly). I tried updating ssd firmware and i checked if the ssd is in AHCI. Nothing worked. Whats wrong with my pc? Thank you for your answers in advanced.

Sounds like there was a hidden boot partition on the hdd from prior to installing windows on the ssd. I'd remove the HDD from the system, do a clean install of windows, and then return the HDD to the system. You should also check the HDD in disk management to see if there is a boot or system partition, and delete it if there is and if that drive is for storage and backup only.

Also, make sure UEFI or UEFI with Legacy mode is enabled in the bios and you may need to enable or disable CSM in the bios. (Compatibility support module)

Furthermore, you might just try removing the CMOS battery from the motherboard for about five minutes, then putting it back and rebooting. This should reset the EFI hardware tables and may resolve SOME issues that can occur after a hardware change.
