I built this new computer a few months ago and have been having this on going issue. When I shutdown windows the computer will act like it is shutting down, hard drives power down and the monitor goes into standby but the fans keep running. I have to manually hold the power button for it to shut all the way off. Any help would be great.
Asus P8Z77-v 8 GB Corsair Vengeance Intel I5 3570k EVGA 670 superclocked 128GB M4 Crucial SSD Older-PC Power and Cooling 550w Power Supply.
Drill through BIOS to see if anything is enabled that might explain the behavior.
Does the same issue occur in Windows safe mode? (If not this could indicate some driver or application causing the issue).
BIOS updated on the motherboard to the latest version?
If issue occurs in Windows safe mode, download & run a free bootable / live OS like Knoppix, Ubuntu, or some pre-builder environment (Bart, etc). This will take the OS entirely out of the equation and answer the question "Is the hardware itself at fault?".
Some ideas to get you going - makes for a fun Sunday.
Edit: My first thought: your power supply is not receiving the proper signal to shutdown operations for whatever reason. It continues supplying power to the motherboard thus the fans still run. Troubleshooting will help confirm. If you have another PSU laying around that you can quick plug in to confirm that'd be the easiest to rule out the PSU itself.
reply to psafux I have a copy of Knoppix laying around, Ill give that a try. My Bios is up to date, Yes it still seems to happen in safe mode. Really annoying. Ill give some of those ideas a try. Thanks.
reply to Hypnotics If you have a powered USB hub hooked to the PC try unplugging it and see if your system will then power down properly.
I have seen a few cases where USB hubs were sending the 5 volt from the external power supply back to the PC and not just to the usable USB ports. The PC's motherboard would see the 5 volts from the hub and refuse to completely power down.
