So a couple weeks ago, I put my PC to sleep with a game running in the background. As I turned it back on, I got a no-signal message on my monitor. It turns out that my driver was corrupted. To resolve my issue, I had to repeatedly reset my PC, re-seat the GPU, and reinstall my known working NVIDIA driver. The thing is, I manage to get my PC working again flawlessly without black screens. I will play most of my games fine (under full load) for 2-5 days...that is, until I turn off the computer or put it to sleep mode. It is ONLY when I turn back on my PC that there is a 20-30% chance of a "no-signal" message. Otherwise, PC is fine for days at a time. At first, I noticed that some Windows updates would coincide with the no-signal incidents. However, I have since disabled automatic driver updates and uninstalled those mentioned updates.
Well it turns out that my PC keeps randomly switching between motherboard and GPU graphics. I know this because when I switch the output cable back and forth between the onboard and GPU slots, the video output comes in, although it is usually my onboard graphics that it is being set to. 90% of the time, my PC seems to be using the onboard graphics. The other 10%, my single GPU. By the way, BIOS is always set to PEG rather than integrated graphics. In BIOS, I have noticed that the motherboard will not detect the GPU (with updated drivers) while running on onboard graphics, although Display Driver Uninstaller is able to detect it.
Also, for some reason, Event Viewer shows a few errors repeating throughout each day (e.g. metadata staging failed, Access to drivers on Windows Update was blocked by policy, Windows failed to resume from hibernate with error status 0xC0000411). My RAM also shows 2.0/7.9GB as opposed to X.X/8.0GB prior to my problem.
Things I have tried to diagnose the problem:
1. Ruled out monitor or cable problem by using back-up cable.
2. Opened case to re-seat GPU and power connector.
3. Ruled out any loose motherboard connections.
4. Placed GPU in 2nd back-up PCIe slot.
5. Used DDU to do a clean install of graphics driver.
6. Completed a re-install of Windows 10 using the "reset Windows" option.
7. Made sure power options were at default, similar to prior to issue.
8. Ran Windows OS diagnostic tools.
9. Checked hard drive for errors.
10. Reset motherboard.
The only thing I have left to do is a complete reinstall of windows, although I doubt this would resolve the problem. As of now, I can fix my problem, and when it returns I have to repeatedly reboot, reconnect output cable, and switch between onboard graphics and GPU.
