Stand by keeps waking up

[NathanMates]

I've got a system that's exhibiting somewhat odd behavior. First, a few HW & SW specs:

MB: Abit AN8 Ultra (using onboard NIC, firewire, PS/2 keyboard port, etc)
CPU: 3800x2
Mem: 2GB (two sticks)
HD, DVD reader, DVD Burner: SATA
Gfx card: ATI x1300
PCI card: Koutech PCI to USB2.0 Card Model IO-PU520. Most USB devices are connected to this

OS: WinXP Home SP2 + all updates.

Symptoms:
When I hit stand by on the system, 10-30 minutes later, it decides to wake up and go to the login screen. It keeps doing this; no human interaction is done. When shut down, it stays that way, but stand by doesn't.

What I've tried:
- Went into BIOS, and I believe I forbade all devices to bring system out of standby
- In device manager, went into keyboard, mouse, and uncheck the 'allow this device to bring computer out of standby'.
- Pinged & tried telnetting to the machine when in standby to verify that the NIC isn't causing a wakeup. It stayed in standby thru these tests.
- Convincing wife to just turn the thing off, rather than wander off and hope it stands by. No success.

Any more places to try looking? Thanks.

Just for giggles, try going to msconfig (start > run > msconfig) and doing a safe start (no services, no start-up items).

Could be some wierd app running that has a wake-up timer set. I've seen wierder things

Nathan,

Go to Control Panel, Power Options and see what your settings are. Windows seems to re-set these for itself... EDIT: Set all the settings the way you want them and save as something like "Nathan's Power" Should help...
