Greetings,

I hope this message finds you well. I am seeking assistance with a perplexing issue I have encountered on my modern HP Pavilion desktop computer.

In recent weeks, I have observed an unusual occurrence where an unidentified character, consistently in the shape of a rectangular bracket, appears unbidden and begins populating text boxes across various programs. This phenomenon transpires intermittently, seemingly at random intervals, and persists despite my attempts to mitigate it through the use of different keyboards, both wired and wireless.

My mouse, which operates wirelessly using what I believe to be Bluetooth technology, functions without issue during these episodes. The situation only arises sporadically, and when it does, it disrupts the normal functioning of my desktop.

I am uncertain whether this anomaly is attributable to electrical disturbances, interface irregularities, or perhaps an underlying hardware fault within the computer system. Any insights or recommendations you could provide would be greatly valued.

Thank you for your time and consideration.
