PC Won't Resume From Sleep!

[bjiddle]

Hey everybody,

I have an FX-6350 (OC) in a Sabertooth 990fx Asus board, with 2x 4gb Hynix 1866mhz RAM, Asus CD/DVD+rw drive, NZXT Sentry 2 Fan controller (reigning over 2x 140mm and 3x 120mm Cougar case fans), a Corsair CX750M power supply, a Sapphire OC Radeon 7850 2gb, an Asus N15 wireless adapter, all in an NZXT Gamma mid tower.

The problem occurred after my rig had been assembled for about eight months. I was running Windows 7 (64 bit), and suddenly my PC would not resume from sleep. HDD turns on, disc drive whirrs, fans go, but no signal is sent to the screen (evidenced by an orange light, turns blue when receiving signal).

I did a fresh install of Windows 8.1 (64 bit) and the issue still occurs. I am basically at my wits end.

I have fiddled with the USB and PCI Express power settings in the control panel, I have updated every possible driver (BIOS too) and even tried different graphics cards and disabling the sound.

Does anyone have any kind of idea or possible solution? I'm a little bit O.C.D. about stuff like this, I'm on the verge of chucking everything and starting fresh.

I had a similar problem after installing an SSD and two things that helped for me were Clearing the CMOS and re-entering my settings and checking that the 24-pin and 8-pin power connectors on the motherboard were in properly.

I don't know why these worked for me, or if they'll work for you, but as shots in the dark, they might be of some use to you. In any case, probably can't hurt.

Hi
If you read the motherboard user guide there is usually a section on bios Uefi settings
One is sleep settings
If fully asleep more difficult to wake up
Try both settings ( usually 2 settings)


The bios reset might do this for you if you changed this from default

Another thought run memtest86 to test Ram as sleep depends on ram

Remove any over clocking of ram in bios settings
