I recently fixed an issue with my computer randomly rebooting, and now, although it was working again, I started encountering this issue where if I turn my monitor off for a few hours, then come back and turn it on, there will be no input, and moving the mouse, or pressing keys does nothing. I know the computer is working, because I have a server running on it and I can still get a ping, but no matter what I do, it won't display any video. I've tried using different cables, a different monitor, and tired plugging the cable into my on-board graphics output instead of my video card, but still nothing. The last time this happened, I turned my computer off by pressing the power button, and then it wouldn't start up again. I had to fix this by starting the computer without the video card, and then putting the video card back in.

 

Here are my system specs:

 

Operating System: Windows 7 Ultimate (Currently not activated)

Processor: Intel Core i5-6500

Motherboard: MSI Z170-A PRO

Memory: G.SKILL Trident Z DDR4-3200 (2x8GB)

Video Card: EVGA GeForce GTX 970 SSC

Power Supply: EVGA 750 BQ

Sounds to me like hardware issues, not relating to monitor if you really tried a working monitor.

 

Failure of both onboard and discrete graphics...would seem to point to motherboard, IMO.

I reset my CMOS and updated my BIOS, and for a while, I wasn't having any problems with this computer, but this morning when I went to turn it on, nothing happened. Unlike the first time, there were no lights coming on in the motherboard, nothing at all is happening. I would think this would suggest you're right and it is a problem with the motherboard, so I'm going to get it replaced.

Well...hardware covers everything from CMOS battery to motherboard to RAM/hard drive.

 

I thnk that I would try to narrow it down...before pumping any dollars into PC components that may not yield any resolution.

 

New CMOS battery would be first on my list.
