New GPU/PSU Sleep Issues

I installed a new GPU (R9 270) and PSU (Cosair 500w) last night. When I wake the PC from sleep it starts and sleeps again (it does this twice) before firing up all the way. It still saves all the open webpages etc.

What might be causing this?

Thank you

    When you send a motherboard in to sleep mode it suspends devices, or puts them into low power mode.
    The working operating system does this through the motherboard bios and its various power state modes.

    If the settings in the bios of the motherboard in the power related section related so sleep modes ect are not set right.
    Then a part or device connected to the motherboard fails to receive a wake up signal for the hardware and driver to resume normal power state.

    Most people never touch this section in the bios, but the right set of modes, can resolve a problem of a device connected to a motherboard where it fails to wake up or resume from a sleep sate, or hibernation mode through windows. Sometimes a manual setting in the bios is needed, based on hardware.

    Yes, I was having problems once I installed the new PSU with the PC not booting from the correct drive. It would only want to boot from the CD drive and HDD, not the SSD (which has the OS). So, I only connected the SSD and it then booted up fine... I then turned off the PC... reconnected the HDD and CD drive. This makes the PC at least boot from the correct drive.

    So, do you think when I was trying to change the boot order in the BIOS I did something wrong? Literally, the only thing I touched was boot 1 and boot 2 trying to get it to find the SSD.

    Update (10Jan2013): Fixed by putting the SSD and HDD on different power cords originating from the PSU. If they were on the same chain there was problems. Novice!
