Hello dear users again. Really appreciate it for helping.
So.
First my pc:
10850K stock 4800mhz with Kraken X73 fans
2x16 GB DDR4 GSKILL 3000mhz XMP
Seasonic Tx-850 Ultra Titanium
Gigabyte Rtx 3090 Gaming OC
Aorus Z490 Pro Gaming
1 TB SSD
Cooler Master Cosmos C700P case


I have an question about my ceiling bulb in room. Weather is normal,no storm etc. Today first time it flickered for 1 second. It happened when i close door in my room ( no more air )
Bulb looking like that:

Is this problem with electric in my house or it was bulb? It flickered ( black ) for 1 second and its fine. Should i worry? All deviced and pc working ok.
My mother turned oven 2 hours before bulb flicker. Maybe because of oven or it was coincedence?

A bulb flickering once is not an issue, likely just a small power change. Not even sure why you listed the computer specs you have since the issue is not with the computer.

So no reason to be worried?
