Hi All, Really hoping someone can help as this is driving me crazy. I was messing around swapping out the PSU in my system and now I find the red HDD activity light stays on permanenent upon shut down and the blue power button LED no longer pulsates as it used to. I actually ended up putting the same PSU back in as I took out and haven't changed anything else in the system. Any ideas what could be causing the HDD light to stay on? I run a Maximus Hero X motherboard and have an M.2 and SSD plus two other older hard drives in the machine.

Hi All I have a thermaltake case which has a blue power light which used to pulsate when shut down. I ended up swapping out the PSU and every since doing that, the blue light no longer pulsates and the HDD red light stays on when the PC is shut down. Any thoughts on what is causing this? I am also running a Coolermaster ML240R twin fan water cooler with an RGB controller and I'm unsure if this is interfering or if it's a bios setting?
