A Mysterious Incident with My PC: Seeking Guidance

In an unexpected turn of events, I recently experienced a bizarre incident with my computer that left me both perplexed and anxious. Allow me to share my story in the hopes that someone can provide clarity or advice.

While engaged in a session of Battlefield 4, I attempted to record some gameplay using my NVIDIA software. In the process, I pressed a series of key combinations to save the footage.
