Just last night when I went to shutdown my PC something odd happened that's never happened before. The PC appears to shutdown normally (monitor goes black/turns off, keyboard and mouse turn off) however, the fans and LEDs kept running. The only way to completely halt the fans/LEDs was to put the power supply switch in the off position.
The specs of the pc are:
Asrock z77 extreme4 mobo
Corsair TX 650W PSU
Nvidia GTX 970
Intel i5 - 3570k CPU
I've tried a couple things by reading other forums and what not online. First I tried resetting the BIOS because apparently the BIOS may have had some sort of issue that kept the fans running. This did nothing, instead for whatever reason it caused the two USB 3.0 ports next to the PS/2 port on the motherboard to stop working. Then I checked all of the other ports because it was kind of concerning to all of a sudden have two ports stop working. Every other audio/USB/HDMI/DVI ports work other than those 2. Now, I'm confused as to what's going on.
The next thing I saw online was how windows 10 apparently has a weird issue with the way it handles power and that disabling the fast startup option may fix the issue. I tried this, and still no luck.
Something else that's incredibly odd is that when the power is turned back on (the switch on the PSU is put into the on position) the fans and LEDS automatically start going before I even touch the power button on the PC.
At this point I believe it is one of two problems: 1) the mobo is dying or is somehow requesting power from the PSU even though the power button was never initially hit. or 2) the PSU is going bad and isnt regulating the power throughout the pc properly. However, I've never come across an issue like this and am very confused. Any ideas on what is going on, or what part(s) I need to replace?
