Monitor won't wake up when PC does

I have this same topic up in the motherboard section. I'm not trying to be a jerk; I just have a hunch that the problem is related and I'm just trying to give myself the best chance at an answer I can.

Just upgraded-these are my core components, before I get any further.

Motherboard: ASRock 990FX Extreme3
CPU: AMD FX 8350 8-core, 4.0 GHz, 16.0 MB Total Cache
Video Card: Gigabyte HD 7850
RAM: 2x8 GB DDR3-1600 Ballistix
Operating system: Windows 7

Anywhere, here's the problem. When my computer goes into sleep mode, the monitor won't wake up with the rest of the system. Every now and then I can get it to, but it never works consistently. Usually I have to power the computer off and on before it works. Even with sleep mode disengaged, it auto-updated WIn7 last night, but the monitor never powered up and I had to turn the thing off then on again.

It's not the monitor, it worked fine on my previous setup about two weeks ago.

I'm honestly not sure what the problem is, but I'm posting it here because most of the people with the same problems I've found online have traced it back to the motherboard, and it's usually fixed by changing "sleep mode" settings or "overvoltage." I'm not new to bios settings but my new one does not have easy to understand settings in those categories, there's nothing called "overvoltage" that I can find and I don't want to randomly change voltage settings also.

Can anyone help? I really need to be able to use the sleep mode setting.

Simple but effective methods , 1.show it to a technician (some problems could not be solve online , better refering an expert). 2- Try to test another monitor with that setup , if it works perfectly then the problem is with your monitor . 3- If the 2nd monitor not working then problem may have been with ur gf card , motherboard or windows(it may have been corrupted) . Also update the Amd driver . 4- if everything fails and the monitor is in warranty replace it.

I had similar problem. When wake up my monitor, the screen stay black. Just enable ''AMD External Events Utility'' in ''services'' and problems gone. My video is 7850
