Just built my third computer on 12/29/12. Everything is awesome except for shutting it down.
Check my specs below then read after for more info please.

No grapics card as of now. Playing WoW on good settings on a 42" 1080p flatscreen with about 25-55 FPS.


When I click shutdown, the computer tries and the screen goes black. It doesn't though follow through though. Case fans stay lit and it just reboots back to desktop after POST.

BUT, after the first attempt to shutdown (which ends in restart to desktop), my mouse turns off and becomes unresponsive. So, I tab through with my keyboard until I get to the shutdown button and try again a second time. This time, since the mouse is off, it shuts down properly.

Is my mouse the problem? I have tried different ports on the motherboard. All USB 3.0.
Here's the thing though, sometimes when I try to shutdown and it just reboots, it will fully reboot with the mouse active. I will have to try 2-3 times before mouse "shuts-off" then navigate through windows with my keyboard and shutdown properly.

Possibilities that I already checked and don't think are the problem:
1. "Wake On" settings in BIOS are all off. LAN, Mouse, Keyboard etc.
2. RAM timings and voltage are correct though BIOS.
3. This was happening for two days even before I overclocked the CPU.
4. BIOS updated to newest firmware.

Please give me your thoughts and advice.

I will select a best answer.

same thing happened to me after a bios update. the fix is to unplug the pc from the wall let the mb drain and then clear your cmos. most times it a glich in the cmos that causes the no shutdown issue.

Ok. I will try that. Should I also remove my motherboard battery?

Tried what you said. No improvement. I figured out what it was. Steel Series Sensei mouse keeping computer awake. Wasn't playing well with my computer. Traded it in for a Razer Naga and it's all perfect. Shutsdown and boots perfectly.

Thanks for the input.
