When I walk next to my PC to take a seat in front of it Ubuntu regularly crashes and the screen begins to blink with all colours of the rainbow. I've already seen this around 25-30 times and it first started happening after I had installed a PCI wifi card (TP-LINK TL-WN851ND) and continues to happen after I replaced the wifi card with another one (TP-LINK TL-WN881ND v.1.0). It seems ridiculous but I can only come to think this is caused by myself interfering the radio signal, especially that when I approach the PC I more or less intersect the straight line between the PC and the wifi router.
Here is what the screen looks like after everything crashes.
Is it even possible that radio signal interference can lead to this kind of behaviour? Would that be a problem with the card driver? How to debug this further? Right now I don't know if I should get a different wifi card or dongle, buy an antenna to get better signal reception or if it's a different component malfunctioning.

That looks to me like video card crash, which has little to do with wifi...unless perhaps your installation introduced an electrical short inside the case, or unless the wifi hardware is defective. WiFi interference and network drops happen many millions of times each day for millions of folks without any crashes....
