My computer will not go into sleep mode, turn off the hard disk, or even go to a screen saver. I manually put it to sleep and it ethier wakes right back up or it waits 5 minutes and comes right back on. I dont have any programs running that should affect it sleeping. I went into the bios and made sure all the wake-up-on settings were off. I tried different power options and settings, and nothing is working. I never had an issue before, the change being that I have a new motherboard and reinstalled windows 7 on a SSD
