Hi everyone!
I've been dealing with a frustrating issue for the past few months, and no matter what I try, I can't seem to fix it.
The problem:
Randomly, both of my monitors lose signal and go black, but my GPU (6700 XT) is still running (fans spinning). The only way to fix this is to hard reboot, then manually enable my GPU drivers in Device Manager, and reboot again to get AMD Adrenaline and the drivers working properly.
This happens unpredictably—whether I'm alt-tabbing from CS2, watching a YouTube video, or viewing a Discord screen share. It's not a GPU crash due to high load, as I’ve run multiple stress tests without any crashes.
Things I've tried (but the issue persists):
- Disabled hardware acceleration in Discord and Chrome
- Swapped PSU cables connected to the GPU (PSU is solid, no issues)
- Changed RAM slots, even tested with one stick at a time
- Reinstalled Windows 11 (twice)
- Updated BIOS
- Tried different undervolt settings
- Downgraded drivers and even tested preview Adrenalin versions (always using DDU for clean installs)
- Checked Event Viewer, but the only error is a Kernel Critical error (since I have to force reboot)
- Pressing Ctrl+Shift+Win+B while screens are black does trigger a beep sound (like plugging in a device), but the displays don’t come back—though this seems to skip the step where I need to re-enable the GPU in Device Manager after rebooting.
PC Specs:
- CPU: Ryzen 7 5700X3D (temps are fine)
- GPU: Radeon RX 6700 XT PULSE
- RAM: 2x16GB Corsair LPX 3200MHz (XMP enabled)
- Motherboard: Gigabyte B550M DS3H
- PSU: Seasonic G-12 GC 850W 80+ Gold
- Storage:
- NVMe: Samsung 980 1TB
- SSD: Kingston A400 960GB
- HDD: Seagate Barracuda 1TB
- Monitors:
- Main: Gigabyte M27Q
- Secondary: BenQ XL2411P
Any ideas on what else I could try? I ran out of ideas and would really appreciate any help!
