Computer does not power down properly

focusbob · 07-18-2009, 01:11 PM

Hello Forum,

I recently built a computer around the Asus P6T Deluxe V2; other components include i7 920, 12gb corsair ddr3 1600, pc power and cooling 910w psu, 4 hdd in raid 0 and 1 arrays, floppy drive plus card reader, and plextor dvdr.

I am dual-booting xp pro sp3 and vista business 64 sp2, and for both OSes when I click "shut down" in the OS, the OS shuts down, the monitor goes into a rest state, but the fans still run and the power is still on. Strangely enough, when I press the default "shut down" button in vista (which isn't designed to power off the system but to put it into deep sleep), the system powers down. In other words, the fans shut off, and the system appears powered down. Because the power does "shut off" when I press the sleep button in Vista, I feel it is not a hardware problem; I'm very open to suggestions though. Every thing else appears stable. The system, at stock settings, has passed 24 hours of memtest86+ and 20 runs of intelburntest.

What's going on? How can I properly shut down my system?

Thanks!
Jim

Most problems that I've had with my P6T Deluxe revolve around the Asus utilities that are installed. As a first step, I'd recommend uninstalling them.

Thanks for your reply.

I havent installed any of the asus software. However I did install the asus acpi driver on both OS installs because the "found new hardware" dialog demanded it. I tried to uninstall the driver in device manager but it wouldn't take. Do you know how to uninstall the driver successfully?

My next step was to reinstall one of the OSes without the acpi driver. But if i can avoid that I would be happy to.
