Question Screen Blackouts on My PC – Need Help Diagnosing the Issue

[br0_ken]

Hi everyone,

I'm facing a recurring issue with my PC where the screen goes black for 1-2 seconds and then comes back. This happens continuously, making it quite frustrating to use. The issue occurs randomly and isn’t tied to specific tasks (gaming, browsing, etc.).

My Current Setup:​

• CPU: Intel Core i5-12600KF
• GPU: Zotac Gaming RTX 3060 Twin Edge OC 12GB
• RAM: 16GB single-channel DDR4 3200 MHz
• Monitor: MSI G255F
• Power Supply: CORSAIR CX650 80 PLUS Bronze
• OS: Windows 11 Pro 23H2

Things I’ve Tried So Far:​

1. Updating GPU drivers (used DDU and clean-installed the latest drivers).
2. Checked HDMI cables to ensure they are securely connected.
3. Tried different ports on both the GPU and monitor.
4. Ensured no overheating issues (GPU and CPU temps seem normal).

Despite these steps, the issue persists. I’m starting to wonder if it could be:

• A faulty GPU or PSU?
• Driver conflicts?
• An issue with the monitor itself?

Any advice on how to diagnose this further or fix the issue would be greatly appreciated. Let me know if more details are needed!

Thanks in advance!

Do you have access to another display (or even TV) that you can test with? This would isolate whether the display itself is the issue.

Understood. Same question regarding the GPU, do you have access to one (or another PC to test your GPU in) that you could swap in to test with?

Looks like your CPU lacks an integrated GPU so that isn't an option.
