Freezes and blackscreen with no errors

Hi everyone,

A few weeks ago (I believe right after a Windows update), I started noticing brief mouse "stutters" during the first minutes after startup — it would happen once or twice, then stop, with no crash. I had never experienced this before.

A few days ago, this escalated: the mouse stuttered, then both my monitors went completely black and the system became fully unresponsive — mouse frozen, no input at all. I had to force a shutdown via the power button.

I checked Event Viewer afterward and found a Kernel-Power Event ID 41 (Critical) with BugcheckCode 0, meaning no clean BSOD or crash dump was written — just a full hard freeze. I also ran a complete hardware diagnostic (UserDiag) right after: 0 WHEA errors, 0 incidents, everything nominal on temps/voltages/components. So the hardware looks completely healthy.

I'm on Windows 11 25H2, using a Razer DeathAdder with Synapse. I just did a full clean uninstall/reinstall of Synapse (using the official CleanupRazerDrivers tool) to see if it resolves the issue — I'll report back in a few days once I've had time to observe.

Hi Rynnh,

 

Based on what you shared, our graphics driver timeout/display subsystem crash or a low-level USB/power state conflict rather than failing hardware. If it’s still not resolved, PM me your Razer DeathAdder’s SN: (Follow steps here: https://mysupport.razer.com/app/answers/detail/a_id/548/~/how-to-find-the-serial%2C-product%2C-or-part-number-on-a-razer-device) and link of your receipt in a PDF format: (Save the shareable files via any online drive account listed here: https://mysupport.razer.com/app/answers/detail/a_id/4011?_ga=2.197232171.544708261.1744067200-1885068520.1744067200&_gl=1*vo487o*_ga_3TRK53PM75*MTc0NDA2NzE5OS4xLjEuMTc0NDA2NzM0My4yNC4wLjA).
