A black screen during a game does not automatically mean the GPU is overheating or that the power supply is too weak. If audio continues, Windows may still be running while the graphics driver, GPU, display link, monitor handshake, or GPU power delivery has failed. First try to recover the display and determine whether the PC is alive; then test one cause at a time.
This article uses the Tom’s Hardware case titled PC Screen Randomly Goes Black During Gaming as a case study. Its marked reply suggested a Windows update or NVIDIA driver issue, but it was not a confirmed, reproducible repair—and the responder said rolling back their own driver did not solve the problem.
What a black screen can actually mean
“The screen went black” describes several different failures. Identify which one you have before replacing hardware.
| What you observe | Most useful areas to investigate |
|---|---|
| Monitor says “No signal,” but audio continues | Graphics driver, GPU hang, cable or port, monitor handshake, or GPU power |
| Black screen with a visible cursor | Explorer, an application, HDR/VRR, display mode, or the Windows compositor |
Win + Ctrl + Shift + B restores video |
Graphics-driver or Windows display-stack failure |
| Audio continues and Caps Lock responds, but video never returns | Display path, driver, GPU, or GPU power fault |
| Sound loops, keyboard stops responding, and reset is required | Full system lockup, RAM/CPU/GPU instability, motherboard, PSU, or firmware |
| The PC powers off or reboots | PSU, protection shutdown, thermal protection, motherboard, or severe hardware fault |
| Only one game triggers it | Game bug, overlay, graphics API, shader compilation, anti-cheat, or game profile |
| It also happens at the desktop | Driver, hardware, Windows, monitor link, power, or broader system instability |
Continuing audio and a Windows device-disconnect sound are useful clues, but neither proves that the driver is at fault. The original case included both symptoms, occurred during games and occasionally light use, and involved an RTX 3070, Ryzen 5 3600X, 32 GB of DDR4, and a Cooler Master MWE 750 White 230V PSU. The poster had already replaced DisplayPort and HDMI cables, clean-installed graphics drivers, and observed normal CPU/GPU temperatures. Read the original case details.

What to do during the next failure
- Reset the graphics driver: press
Win + Ctrl + Shift + Bonce. Windows may beep or flicker. If video returns, record the exact time and continue diagnostics. - Test keyboard response: press Caps Lock or Num Lock and watch the indicator.
- Try another Windows path: use
Alt + Tab,Ctrl + Alt + Delete, orWin + P. - Listen: note whether game audio continues normally, loops, stops, or produces a device-disconnect sound. Also note whether fans ramp up or stop.
- Check the monitor: if it reports “No signal,” power-cycle the monitor once and verify its selected input.
- Hard-reset only if necessary: hold the PC power button when nothing responds. This can lose unsaved data and may obscure the original failure.
Collect evidence after rebooting
Reliability Monitor
Press Win + R, enter perfmon /rel, and inspect the failure time. Look for hardware errors, Windows failures, display-driver failures, game crashes, and driver or Windows updates installed shortly before the event.
Event Viewer
Open Win + X → Event Viewer → Windows Logs → System. Inspect events around the exact timestamp, including display-driver recovery or timeout messages, WHEA hardware errors, PCIe or device-reset errors, unexpected shutdowns, and Kernel-Power Event ID 41.
Event 41 normally means Windows did not shut down cleanly; it does not identify the failed component or prove that the PSU is defective. Record the source, event ID, timestamp, and message instead of treating any generic “critical” label as a verdict. Microsoft’s Event Viewer documentation explains the tool’s role.
Also record the GPU driver version and installation date, Windows version and recent updates, GPU and CPU clocks, GPU core/hotspot/memory temperatures where available, power readings, whether the monitor says “No signal,” and whether the failure occurs at a consistent load.

1. Test the display path
- Use only the primary monitor and disconnect the second display completely.
- Try another output on the GPU.
- Test HDMI instead of DisplayPort, or vice versa.
- Temporarily reduce refresh rate and disable HDR and variable refresh.
- Remove docks, KVM switches, adapters, risers, extension cables, and capture devices.
- Test the monitor with another computer, or test the PC with another monitor or television.
- Confirm the cable is connected to the graphics card, not the motherboard video output.
Replacing cables alone does not eliminate a faulty monitor, GPU port, refresh-rate negotiation, multi-monitor conflict, adapter, or signal-handshake problem.

2. Disable overlays and background utilities
Temporarily disable the NVIDIA App or GeForce overlay, AMD Adrenalin overlay, Steam and Discord overlays, Xbox Game Bar, MSI Afterburner/RivaTuner overlays, browser hardware acceleration, RGB and motherboard-control utilities, recording software, capture tools, streaming software, and remote-control software. If the problem stops, re-enable them individually to find the conflict.
3. Return everything to stock
Disable GPU overclocking, undervolting, custom fan curves, and power-limit changes. Temporarily disable CPU overclocking and return XMP, EXPO, or DOCP memory settings to default. If many BIOS changes have accumulated, load optimized defaults. Change one variable at a time and test the same game for a comparable period.
Normal temperatures do not prove stability. Memory timings, GPU voltage, hotspot or memory temperature, transient load, firmware, and power delivery can cause failures even when average CPU and GPU temperatures look normal.
4. Perform a controlled graphics-driver reinstall
- Download the current driver directly from NVIDIA, AMD, or Intel.
- Download the appropriate motherboard chipset driver from the platform or motherboard vendor.
- Create a restore point or backup.
- Temporarily disconnect from the internet if Windows keeps replacing the driver during testing.
- Uninstall the existing graphics package, then reinstall using the vendor’s clean-install or factory-reset option.
- Install only necessary driver components initially.
- Test before reinstalling overlays, tuning tools, recording software, RGB utilities, and third-party monitors.
If ordinary cleanup fails, Display Driver Uninstaller can be used as an escalation step. It is not required for every black-screen case. Do not treat the 2021-era NVIDIA 466.77 rollback discussed in the forum thread as a current universal fix; the responder said it did not solve their own system.
5. Check Windows and platform integrity

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannowThese can repair Windows component or system-file corruption, but they are unlikely to repair a defective GPU, PSU, monitor, or cable. Check Windows Update history when correlating a failure with a recent update, and update or roll back BIOS and chipset software only according to the motherboard vendor’s instructions.
6. Reseat the GPU and inspect power delivery
Shut down, unplug the PC, and press the power button briefly before working inside it. Reseat the graphics card and confirm the retention latch is engaged. Reconnect GPU power plugs firmly, use separate PCIe power cables where the GPU requires multiple connectors, and inspect connectors for looseness, discoloration, heat damage, or melting. Never substitute modular PSU cables from another unit. Check the motherboard’s 24-pin and CPU EPS connectors as well. If using a vertical mount or riser, test without it.
A “750 W” label is not enough to establish PSU suitability. Model, revision, age, condition, cabling, GPU transients, and system configuration matter. The exact Cooler Master MWE 750 White 230V model in the case was therefore worth investigating—not merely its wattage.
7. Test temperature and stability by component
Use a sensor tool such as HWiNFO to log GPU core, hotspot, and memory temperatures where exposed; CPU package temperature; GPU power, clock, voltage, and fan behavior. Note whether readings stop updating when the screen fails.
Run tests separately: GPU-only, CPU-only, combined CPU/GPU, and memory. OCCT can help with component-specific load testing, while MemTest86 provides bootable memory testing. A quick synthetic failure is meaningful evidence. A passing test does not prove the PC is healthy in every game, because games exercise different APIs, shaders, memory patterns, overlays, and power transients. Do not run every stress test simultaneously.

8. Check RAM and platform stability
Run a bootable memory test. If errors appear, test one DIMM at a time, verify the modules occupy the motherboard’s recommended slots, and leave XMP/EXPO/DOCP disabled. WHEA errors can indicate hardware or PCIe instability. Clearing CMOS may return settings to default, but it does not repair defective hardware or identify the cause.
9. Test the PSU by substitution
A PSU becomes more suspicious when the PC powers off or reboots, failure occurs during combined CPU/GPU load, the unit is old or damaged, connectors show heat damage, or a known-good PSU makes the problem disappear. Substitute a known-good, appropriately rated PSU with native connectors and suitable regional voltage—not simply a larger wattage number. Never open a PSU.
10. Consider GPU failure or RMA
GPU failure becomes more likely when the problem persists across games and at the desktop, survives a second monitor and cable, continues at stock settings after a clean driver installation, appears during GPU-only testing, or is accompanied by artifacts, repeated driver resets, WHEA errors, or PCIe errors.
The strongest evidence comes from substitution: if the fault follows the GPU to another compatible system, or a known-good GPU works normally in the affected PC, stop endlessly tweaking and pursue repair or warranty service.
Use this decision tree
- The shortcut restores video: prioritize a clean driver test, another driver version, disabled overlays and tuning tools, stock GPU/RAM settings, and single-monitor testing.
- Audio continues but the shortcut does nothing: prioritize single-monitor and alternate-port tests, GPU reseating, power inspection, stock settings, and known-good PSU or GPU substitution.
- The whole PC freezes: prioritize memory testing, BIOS/chipset checks, removal of overclocks and memory profiles, WHEA review, and individual component testing.
- The PC turns off or reboots: prioritize PSU and power cabling, temperatures and hotspots, motherboard power delivery, and known-good PSU substitution.
- Only one game fails: verify game files, update the game, try another graphics API, cap the frame rate, reset graphics settings, test borderless/windowed mode, disable that game’s integrations, and check its official support channels.
What not to do
- Do not disable Windows TDR through registry changes such as
TdrLevel = 0as a first-line fix. That can remove the recovery mechanism and turn a recoverable driver hang into a longer freeze. - Do not assume normal average temperatures rule out hotspot, memory, VRM, transient-load, RAM, driver, or firmware problems.
- Do not interpret Event 41 as proof of a bad PSU.
- Do not buy a larger PSU solely because its wattage number is higher.
- Do not flash BIOS or firmware without following the manufacturer’s recovery procedure.
- Do not replace an expensive GPU after one failure or a single driver timeout.
When to stop troubleshooting
Move to RMA, repair, or professional diagnosis after repeated failures at stock settings; failure with multiple displays, ports, and cables; a clean driver installation; confirmed GPU, RAM, PCIe, or WHEA errors; a fault that follows the GPU; or a problem that disappears with a known-good PSU. Stop immediately if there is a burning smell, visible connector damage, melting, or repeated power cutout.

Before contacting a manufacturer or repair shop, document the GPU serial number, driver and Windows versions, reproduction steps, temperatures and power readings, timestamps, Event Viewer and Reliability Monitor evidence, and every substitution test. This makes the diagnosis faster and reduces the chance of replacing the wrong component.
The forum case: useful clue, not a confirmed solution
The original poster’s RTX 3070/Ryzen 5 3600X system had continuing audio, a disconnect sound, black screens during games and occasional light use, replaced cables, clean-installed drivers, normal observed temperatures, and a Cooler Master MWE 750 White 230V PSU. The marked reply suggested checking for a display-driver recovery message and suspected a Windows update or NVIDIA driver issue. However, it did not establish that the original poster confirmed that diagnosis, and the responder reported that rolling back their own driver did not fix their system. The thread is better treated as an unresolved troubleshooting report than as a universal solved fix.
Frequently Asked Questions
Does continuing audio prove that the GPU driver crashed?
No. It shows that at least part of the system may still be running, but the cause could be the driver, GPU, monitor link, cable, port, or GPU power delivery.
Does Kernel-Power Event 41 prove the PSU is bad?
No. It generally records that Windows did not shut down cleanly. Use it with timestamps and other evidence; confirm a PSU fault with proper substitution testing.
Free tools Windows power users keep installed
One-click scans. No signup required.
Should I use Display Driver Uninstaller for every black screen?
No. Start with the vendor’s normal clean-install process. Use DDU only when repeated driver installations or remnants appear to be involved.
When should I RMA the graphics card?
After stock-setting tests, clean driver installation, display-path checks, memory testing, and appropriate PSU substitution still reproduce the failure—especially if the fault follows the GPU.
The Bottom Line
Start by determining whether Windows is still responsive, then test the display path, overlays, stock settings, driver installation, power connections, RAM, temperatures, and component substitutions in that order. The forum thread’s driver theory is plausible but unconfirmed; the evidence, not the marked label or a single Event Viewer entry, should determine whether the culprit is the GPU, PSU, monitor path, or another component.
