Hardware Image disappears from monitors but backlight is still on

[Phil Smith]

Hi guys,

Last week I've started getting very annoying PC behaviour - when you load the GPU even slightly (watching youtube videos, opening new windows, working in CAD programs, etc.) an image just disappears from monitors, but back light is still on. The PC itself freezes almost instantly (sometimes it's right away, sometimes it takes several seconds, I can tell it by pressing either capslock or numlock and looking at them corresponding lights on the keyboard).
The only way to get images back is to reboot the machine by holding power button for 5 sec.

I've taken a look at the Event Viewer and there is nothing related to that issue whatsoever.
I've tied to update the GPU driver and rolled back to earlier versions - nothing changed.
I've changed GPU's thermal paste - nothing changed.
I've installed a fresh copy of Win10 on another hard drive, but after installing a GPU driver I had the same problem again.
The only thing that works is to uninstall graphics drivers altogether - it's very limited (e.g. I cant extend image between 2no screens, etc.), but at least it doesn't freezes all of the sudden..

PC specs are as follows:
AS Rock X99 OC formula mobo.
Intel i7 CPU
32 GB RAM
AMD Sapphire Nitro R9 390 8Gb GPU
OS is Win10 pro x64.

Has anyone encountered that issue?
Any help will be much appreciated..

I only remember such an issue from a really old Geforce 2 GPU, and thats likely a hardware fault then.

After all those unsuccessful attempts to find a solution I'm starting thinking the same thing.. too bad I had tossed all my old pc components, I would've been able to swap the GPU just to verify it is indeed the culprit.

You might also check your monitor with something else, if its maybe the culprit, like a short circuit in the cable. But I doubt that and if thats the case, you at least prevent your next GPU from the same fate.

Good shout, but my setup has 2x monitors and both of them blank out in the same time. I'll check them with my laptop anyway, just in case. BTW, I've tried to swap cables and ports, but the issue still appears.
I've ordered a new GPU (GeForce 4060), it should arrive tomorrow, will see.
Anyway, thank you, Urwumpe
