Computer Turns On by Itself - Windows 7 x64
I never use sleep or hibernate mode, I always shut down. Sometime between 10 minutes and one hour after shutting down the computer starts up again.
Computer:
Intel i5-2500k
ASRock Z68 Extreme4 Gen3 (Bios P2.20 Latest)
16GB 1600 RAM
OCZ Vertex 3 120GB
Hitachi 1TB drive
HD6850 Graphics
Built the machine 6 months ago, recently had an issue of the system locking up. Isolated the issue as OS corruption. I restored from a Windows backup from one month prior, issue went away, but this new issue showed up. While I was debugging that issue I flashed the latest firmware to the Motherboard. Also, I doubt it's the power button since the issue started after a software change.
BIOS Settings:
CPU Configuration
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Enabled
CPU C6 State Support: Enabled
Package C State Support: Auto
Southbridge Configuration
Deep Sleep: Enabled in S5 (I have tried disabling this also)
Restore on AC Power Loss: Power Off
ACPI Configuration
Suspend to RAM: Disabled
Boot
Boot from onboard Lan: Disabled
Windows Settings:
Device Manager -> Network Card -> Power Management
Allow this device to wake computer: Unchecked
I saw this post and tried to follow as many suggestions as possible before starting a new thread. One thing is the task scheduler. I'm not sure what to look for in the scheduler which would allow a task to wake the machine. At least I've never heard of a task doing that before.
Any suggestions what else to look at?
Thanks in advance
