recognize a high resistance arcing fault such as
those commonly associated with extention cord fires
by its electronic 'signature').
The thermal portion of the trip sensor is for overloads.
If that panel is being externally heated, the breakers may
well trip at lower than rated currents.
I'd suggest shading that panel.
Don't restrict air circulation though."
This is a complete guess but try running the computer through a UPS.

In my experience with the arc fault breakers and the laser printer I had that would trip it, an electrician showed me a trick. It can actually happen because the hot wire is too close to the grounded receptacle box (I believe that was his explanation). He shut the breaker off, pulled the receptacle out of the box, neatly fed the wires back in, and the problem was solved. Someone with more electrical background than me can probably explain why that happens, but in my case, simply removing (not disconnecting) the plug and then neatly reinstalling it in the receptacle box was all it took, and the circuit on that breaker has been flawless ever since.
Also - the bathroom outlet is a GFI, so if in fact there was a ground fault (short circuit) in your PC at the power supply level, the GFI would have tripped right away. If the machine POSTS (gets to the BIOS screen) without beeps in the bathroom, there's probably nothing wrong with the PC.
