In Basic terms the conditions that come into play are:
Faraday Cage (shield surrounding most desktop computers usually a metal case and limits radio interference and susceptance int the US its to meet FCC requirements other countries have equivalents) .
Wavelength of transmission and antenna performance. Basically to transmit or receive you need an antenna. The minimum size of an optimum antenna is 1/4 wavelength of the signal frequency. For a PCB circuit board at 1GHz this would be around 2-4 cm. In silicon oxide this reduces by around 65% but its still large when compared to chip-scale dimensions. Increasing the transmission frequency will reduce the size of the antenna needed, but comes with other equally degrading issues such as receiver sensitivity degradation with frequency and propagation length reduction due to atmospheric effects, and many more)
Interference for example a cpu clock running at 1GHz will have specific harmonics at 1GHz,3GHz,5GHz, 7GHz..etc. But data is a different story, due to the random nature it will have a spectral content that will fill in the frequencies between the clock harmonics.
Most of these degradation's can be can be overcome by increasing the transmission power and/or transmitting at a close range. So if the transmitted power to your PC was high enough, it may be enough to get a signal through and cause a strange operation. But this would make it easy to locate the transmitter and catch the spy.
There are far easier ways to explain this problem.
I have an HPpavilion 6000 laptop I bought from Costco after a year the display started acting weird so I looked to the internet and woa and behold others where experiencing the same thing. Its clearly a design flaw, but what if there was a bad batch of connectors that were installed on a batch of motherboards at around the same time and we were the unlucky population that experienced the same issue after around a year of regular use.
Incorrectly written software drivers can cause the same set of issues. Thermally hardware can reset or act strange and degrade with time.
Finally improperly written software or software that operates on one platform acts differently on another. This is the big headache Microsoft has to deal with, while Apple doesn't because of the limited hardware platforms. Complex systems such as computers do strange things and usually have to be corrected when the bug is reported to the developer and thus corrected.
You may be being hacked by some one who wants to do you in, or you may be experiencing some kind of more likely problem. Don't let the excitement of a clandestine operation interfere with root-causing the real issue.
