So I decided to build my own computer about 3 weeks ago. Everything went smooth however I noticed a pretty nasty issue when the computer goes to sleep. Indeed when it goes to sleep for more than something like 3 hours, trying to awake it through a mouse move or a keyboard press doesn't seem to work. Actually it's starting to awake (I can see the fans' leds flashing) but about one second later it shut down and the only way to restart my computer is by rebooting it through a five second press on the power button. I updated all my divices drivers and got all available windows update but it's still doing the same thing. So I really don't know what's going on.
My computer :
- Case : Antec DF-35
- PSU : Corsair Enthusiast Series TX850 V2 80PLUS Bronze Certified 850W
- Motherboard : Asus SABERTOOTH P67
- CPU : Intel Core i7-2600
- Graphic card : Sapphire AMD Radeon HD 6970 2GB GDDR5
- DVD reader/writer : LG GH24NS50 24xDVD+R/-R 8xDVD+RW/6xDVD-RW 16xDVD+R
- HDD : Western Digital Caviar Green (WD20EARS) 2000GB (2TB) SATA 3 Gb/s 64MB
- RAM : G.SKILL Ripjaws X Series DDR3 1600MHz (PC3-12800) 8GB (2x4GB)
- Keyboard : Logitech K350 (wireless)
- Mouse : Logitech Mx Revolution (wireless)
- Screens : 2x DELL ST2320L (1 in HDMI and 1 in DVI)
- OS : Windows 7 Ultimate (Service Pack 1)
What I've tried so far :
- Updated all devices drivers and OS
- Enabling the EPU power saving mode in the bios (EFI)
- Enabling the PLL internal overvoltage in the bios (EFI)
- Disabling the hybrid sleep in "power options" under windows
- Disabling the hibernate after in "power options" under windows
And right now, I don't know what to do...
