Computer won't sleep
I recently installed Windows 7 on my old Asus P4C800-E system. The CPU is a P4 Prescott 3.2 gHz. Video card is a Gigabyte Radeon HD 4650. Sound is USB Turtle Beach Audio Advantage. 2 GB memory.
The system is set to sleep after 30 minutes. It doesn't go to sleep. My keyboard has a sleep button. When I press it, the computer sleeps and them immediately wakes. I've checked that everything has been set correctly. Any ideas why it won't sleep?
