Computer turns back on 3-5 seconds after pressing sleep

A few days ago, my computer stopped sleeping. When I press the sleep button, my screens will fade to black, and then just turn back on again after a few seconds. I can't think of anything that changed to cause this. I have tried:

• Sleeping from the command line (same result as button)
• Closing amp WinOFF (had this for a while, but just to be sure)
• Disabling Wake-On-Lan
• Unplugging nonessential devices
• System restore - Failed
• Unplugging my DP monitor, in case it was that weird power issue I've heard about

The only think I can think of that might have caused it is a system update. Does anyone either know how to fix this, or a place I could find an error log? I couldn't find anything myself in Event Viewer, but I'm not an expert at it. Also I doubt this is worth noting, but it sets my Skype to offline. System specs are relevant. Any ideas?

This is almost always the display adapter. Try upgrading it or rolling back to another that worked.

Other Power Options and Sleep Mode Problems

Lastwake and the event log turned up nothing for me. I'm guessing it's the graphics drivers, AMD recently released new ones: Previous

Should I downgrade to 14.4 then, or try reinstalling 14.9? I had some sort of error during the last install.

I'd try the lastest display driver. See if you can find it without the ATI software package.

Ah, thanks maxie. There was a message saying drivers are interfering from Windows entering sleep mode and one message saying programs are preventing Windows from entering sleep mode. The program was AMP WinOFF, however, after uninstalling it, it still wouldn't sleep. The drivers were AMD multi-vendor Miniport Driver and VirtualBox Bridged Networking Drivers. Also, if it's relevent, there were 3 drivers that were slowing down resume from sleep, two of which were "Etrom eXtensible Hub Driver, whatever that is. Last was Windows Driver Foundation - User-mode Driver Framework Reflector. Here is the pop-up boxes.

Ok, don't ask me how, but I managed to downgrade my display drivers and I can sleep again. The (un)installers didn't exactly work, but after rebooting I somehow managed to be on CCC 14.4. Now, my computer randomly wakes up. Power-Troubleshooter shows various times such as 3:00 AM, 3:31AM, 6:12AM, 6:20AM, etc. All lastwake is telling me is that the "Power Button" turned on my computer, which is definently a lie. I think I'll try to apply that bios update, unless you guys have any better ideas. Is there somewhere that will tell me what actually turned on my computer?

Uninstall CCC bloatware and install only the display driver.
